DETAILED DESCRIPTION

[0028] The specific embodiments of the present application will be further described in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but not to limit the scope of the present application.

[0029] In the description of the present application, it should be understood that the terms "first", "second" and the like in the specification and claims of the present application and the above-described drawings are intended to distinguish similar objects and are not intended to describe a particular sequential or chronological order. It should be understood that such terms can be interchangeable under appropriate circumstances so that the embodiments of the present application can be practiced in other than the illustrated or described order. Furthermore, "include", "have", and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a list of components, steps, or units is not limited to those components, steps, or units explicitly listed, but can include additional components, steps, or units not expressly listed or inherent to such process, method, system, product, or apparatus.

[0030] As shown in FIGS. 1, 2, and 3, a gas reactor 10 according to an embodiment of the present application preferably comprises a kettle body 101, a kettle cover 102, a pedestal 103, a gas inlet end 104, a gas outlet end 105, a plurality of metal probes 106, and a plurality of signal lines 107. Figure 1 2 The kettle body 101 and the kettle cover 102 constitute a reaction cavity. The pedestal 103 is installed on the inner bottom of the kettle body 101, and the pedestal 103 is made of insulating material. The gas inlet end 104 is used to introduce external gas into the reaction cavity. The gas outlet end 105 is used to discharge gas in the reaction cavity. The metal probes 106 are detachably assembled on the bottom of the kettle body 101, and one end of the metal probes 106 abuts against the pedestal 103. The signal lines 107 are in conduction with the metal probes 106, and the signal lines 107 pass through the kettle body 101 to be in conduction with an electronic detector.

[0031] The kettle body 101 and the kettle cover 102 constitute a reaction cavity. The pedestal 103 is installed on the inner bottom of the kettle body 101, and the pedestal 103 is made of insulating material. The gas inlet end 104 is used to introduce external gas into the reaction cavity. The gas outlet end 105 is used to discharge gas in the reaction cavity. The metal probes 106 are detachably assembled on the bottom of the kettle body 101, and one end of the metal probes 106 abuts against the pedestal 103. The signal lines 107 are in conduction with the metal probes 106, and the signal lines 107 pass through the kettle body 101 to be in conduction with an electronic detector. ​

[0032] It can be understood that, in order to facilitate the observation of the structure in the reaction cavity, the kettle cover 102 is cut in the drawings. Figure 1 and Figure 2 The kettle cover 102 is cut in the drawings.

[0033] Through the above scheme, a plurality of metal probes 106 are arranged in the gas reactor 10, and the metal probes 106 are detachably assembled at the bottom of the kettle body 101, and one end of the metal probe 106 abuts against the support 103 made of insulating material. At the same time, the signal line 107 is in conduction with the metal probe 106, and is connected with the electronic detector through the kettle body 101.

[0034] The abutting structure enables the metal probe 106 to contact the material when the material is placed on the support 103. Through the connection of the signal line 107 and the electronic detector, the electrical parameters of the material in the gas reaction process can be detected in real time, such as the change of electrical conductivity, current-voltage characteristics, etc. Compared with the traditional gas analyzer which lacks the function of detecting electrical parameters, the blank of directly detecting the electrical parameters of the material in the gas reaction environment is filled.

[0035] It can be understood that the fixing structure can adopt various forms, such as clamping, screw fixing, elastic extrusion, etc.

[0036] In order to improve the stability of the electrical signal of the abutting connection, the metal probe 106 in the present application can adopt a metal material with a certain elasticity. In order to reduce the error of the collection of the electrical signal, a metal with strong conductivity can be used as the metal probe 106 in the present application, or a material with strong conductivity can be used as a coating for the metal probe 106.

[0037] In an embodiment, the metal probe 106 can adopt copper material as the base material and silver material as the metal coating, which can provide better chemical stability while ensuring high conductivity, so as to reduce the influence on the material and gas reaction process.

[0038] It can be understood that, in order to adapt to different gas reaction environments, the metal probe 106 in the present application can be detachable, so as to be replaced for different experiments.

[0039] The type of the electronic detector in the embodiment of the present application is not limited, and various common types of electronic detectors can be used in the present application. For example, a common multimeter can measure the basic electrical parameters of the material in the gas reaction process, such as resistance, current and voltage, etc. Through the connection with the metal probe 106 and the signal line 107 in the gas reactor 10, the changes of the electrical parameters of the material can be directly reflected.

[0040] There is also an electrochemical workstation, which is more powerful and can perform various electrochemical tests such as cyclic voltammetry and chronoamperometry. In the gas reactor 10, the electrochemical workstation can be used to deeply study the electrochemical reaction process of the material in the gas environment, obtain information such as reaction mechanism and electrode kinetics, and has important significance for analyzing the change mechanism of the electrical properties of the material when it interacts with the gas.

[0041] In addition, an impedance analyzer is also a viable option. It can accurately measure the impedance characteristics of the material, including the comprehensive changes of resistance, capacitance, and inductance parameters. When the material's electrical properties change due to the influence of the gas, especially when the dielectric properties change, the impedance analyzer can provide detailed and accurate data to help researchers fully understand the changes in the material's internal microstructure.

[0042] In summary, whether it is a simple multimeter or a complex electrochemical workstation, impedance analyzer, etc., it can be adapted to the gas reactor 10 in this application to meet the needs of detecting the electrical properties of materials under the action of gas in different scenarios.

[0043] In an embodiment, the gas reactor 10 can also include a light-transmitting piece 108, and a xenon lamp light source is suspended above the cover 102 and shines downward. The cover 102 is provided with a light-transmitting hole 1021, and the light-transmitting piece 108 is installed in the light-transmitting hole 1021, and the light-transmitting piece 108, the object table 103, and the xenon lamp light source are centrally aligned.

[0044] The above structure enables the reactor to simulate a photocatalytic reaction environment. In many material researches, photocatalytic reaction is an important research direction, such as in the fields of photocatalytic degradation of organic pollutants and hydrogen production by water photolysis. Through this reactor, researchers can study the changes in electrical properties and chemical reaction processes of materials under the combined action of gas atmosphere and light. It is beneficial to develop new photocatalytic materials and optimize photocatalytic reaction conditions.

[0045] At the same time, the xenon light source 14 can generate heat while providing light, and the heat of the light radiation has the characteristic of not needing to be in contact. The object table 103 is located below the light source, and the material placed on it can uniformly receive the heat radiated by the light source, while the gas is introduced into the reaction chamber through the gas inlet end 104.

[0046] Compared with the traditional contact heating method, radiation temperature adjustment avoids pollution or interference that may be caused by direct contact between the heating element and the material, ensuring the accuracy of the experimental results. Combined with precise control of the type, flow rate, and concentration of the gas, it can provide a stable and reliable experimental environment for the performance research of materials under different gas and temperature combinations, and help to deeply explore the influence mechanism of the synergistic effect of gas and temperature on material performance.

[0047] It can be understood that the metal probe 106, the xenon light source 14 or other structures do not need to be used at the same time, and the specific structures used are determined according to the purpose or requirement of the experiment currently performed, and the application does not limit this. The scheme formed by the cooperation of various structures should fall within the protection scope of the application.

[0048] In the application, the light-transmitting piece 108 can be fixed in a conventional manner, such as gluing, integral molding, bolt fixing, etc.

[0049] In order to improve the fixing effect, in an embodiment of the application, the gas reactor 10 can further include a ring nut 109, the light-transmitting hole 1021 is a threaded stepped hole, the light-transmitting piece 108 abuts against the stepped surface of the threaded stepped hole, and the ring nut 109 is threadedly matched with the threaded stepped hole to press the light-transmitting piece 108.

[0050] Through the cooperation of the ring nut 109 and the stepped threaded hole, the light-transmitting piece 108 can be uniformly pressed to reduce the probability of warping or deformation of the light-transmitting piece 108. At the same time, due to the structural characteristics of the ring nut 109, the middle part of the ring nut 109 is hollow, so it will not affect the transmission of light. And because the threaded cooperation has the property of being detachable, when it is necessary to clean or replace the light-transmitting piece 108, it can be more convenient to achieve. Therefore, the design of the ring nut 109 and the stepped threaded hole can not only achieve uniform fixing effect, but also does not affect the transmission of light, and is convenient for disassembly and replacement.

[0051] In the application, in order to facilitate the taking and placing of solid experimental materials, in an embodiment, the kettle body 101 and the kettle cover 102 are assembled by a plurality of hand-tightening bolts.

[0052] The assembly mode of the hand-tightening nut 110 makes the kettle body 101 and the kettle cover 102 more easily disassembled and assembled, so as to achieve the purpose of quickly opening to place solid experimental materials (such as catalysts, etc.).

[0053] Correspondingly, as shown in Figure 3 , Figure 4 and Figure 5 , Figure 6 , the application further provides a material evaluation device 1, which can include a first gas inlet channel 11, a second gas inlet channel 12, a first three-way joint 13, a gas reactor 10 and a first detection port 15.

[0054] The first three-way joint 13 is used to connect the first gas inlet channel 11 and the second gas inlet channel 12, and is also used to connect the gas inlet end 104 of the gas reactor 10, and the gas reactor 10 is used to provide a reaction space for the mixed gas or the catalyst.

[0055] The first detection port 15 is in communication with the gas outlet end 105 of the gas reactor 10, and is used to connect a chromatograph or to be vented.

[0056] It can be understood that, in the present application, since the material evaluation device 1 in any embodiment includes the gas reactor 10, the beneficial effects of the gas reactor 10 and the embodiments are used in the material evaluation device 1 in the present application.

[0057] In addition to the first gas inlet channel 11 and the second gas inlet channel 12, the material evaluation device 1 in the present application can also include other gas inlet channels, which can refer to the structure of the first gas inlet channel 11 or the second gas inlet channel 12, and the present application will not repeat it here. As shown in the drawings, different gas inlet channels can be connected by a three-way.

[0058] In an embodiment, the first gas inlet channel 11 or the second gas inlet channel 12 can also include a mass flow controller 16 for controlling the gas flow in the gas inlet channel according to an electrical control signal.

[0059] In a gas reaction experiment, the flow rate of the gas is a key factor affecting the progress and results of the reaction. The mass flow controller 16 can accurately control the gas flow in the gas inlet channel according to the electrical control signal, which allows researchers to accurately set the flow rate of different gases to a specific value according to the experimental requirements, thereby accurately adjusting the proportion of mixed gases.

[0060] For example, in some experiments that require a specific proportion of mixed gases for catalytic reactions, the mass flow controller 16 can accurately control the inflow of each gas, ensuring that each experiment can be performed under the same gas ratio conditions, greatly improving the accuracy and repeatability of the experiment.

[0061] In an embodiment, the material evaluation device 1 can also include a gas washing bottle 17 and a four-way ball valve 18.

[0062] The gas washing bottle 17 includes a storage part 171 that stores deionized water or volatile solution. The four-way ball valve 18 is installed between the first three-way 13 and the first gas inlet channel 11, and when two ends of the four-way ball valve 18 are in communication with the first gas inlet channel 11 and the inlet of the gas washing bottle 17, the other two ends of the four-way ball valve 18 are in communication with the outlet of the gas washing bottle 17 and the first three-way 13.

[0063] The four-way ball valve 18 is installed between the first three-way 13 and the first gas inlet channel 11, and through the ingenious conduction design, the flexible switching of the gas path is realized. When two ends of the four-way ball valve 18 are connected to the first gas inlet channel 11 and the inlet of the gas washing bottle 17, and the other two ends are connected to the outlet of the gas washing bottle 17 and the first three-way 13, the gas can be guided to the gas washing bottle 17 for purification or modification treatment before entering the gas reactor 10. When such treatment of the gas is not required, the conduction state of the four-way ball valve 18 can be switched to allow the gas to directly enter the first three-way 13 from the first gas inlet channel 11, thus conveniently and quickly meeting different experimental requirements and improving the flexibility and efficiency of experimental operation.

[0064] The storage part 171 in the gas washing bottle 17 stores deionized water or volatile solution. When the gas passes through the gas washing bottle 17, if the storage is deionized water, water-soluble impurities such as acidic gas and dust particles easily soluble in water in the gas can be effectively removed, the gas entering the reaction system is purified, the interference of impurities on the reaction result is reduced, and the accuracy of the experiment and the purity of the product are improved.

[0065] If it is a volatile solution, part of the volatile solute will be carried by the gas during the passing process, thereby modifying the gas, which provides a possibility for specific gas experiments and expands the research scope of the experiments.

[0066] For example, in the reaction experiment of ammonia gas and carbon dioxide carrying volatile acetic acid, the product and characteristics of the reaction of carbon dioxide carrying volatile acetic acid and ammonia gas are explored. In the experiment, carbon dioxide can be made to pass through the gas washing bottle 17 containing acetic acid solution, so as to carry acetic acid molecules, and then mixed with ammonia gas at the first three-way 13 and then enters the gas reactor 10. After the reaction is completed, the product is collected and analyzed by using an infrared spectrometer, so as to study the influence of volatile substances on the reaction of the two gases, and provide a basis for chemical production and reaction mechanism research.

[0067] On this basis, in an embodiment, the gas washing bottle 17 can further include a temperature control pipeline 172. The temperature control pipeline 172 is arranged around the storage part 171, and the temperature control pipeline 172 is used to pass in a liquid to heat or cool the liquid stored in the storage part 171.

[0068] When the gas washing bottle 17 is used to absorb gas, the temperature affects the solubility and absorption rate of the gas in the solution. The temperature control pipeline 172 can adjust the temperature of the solution to the optimal absorption range, improve the gas absorption efficiency, and make the gas purification or separation more thorough. For example, when sodium hydroxide solution is used to absorb carbon dioxide, controlling the appropriate temperature can enhance the absorption effect.

[0069] The solubility of the gas in the solution is different at different temperatures. By adjusting the temperature through the temperature control pipeline 172, the solubility of the gas can be accurately controlled to meet specific experimental requirements, such as controlling the amount of chlorine gas dissolved in the preparation of saturated chlorine water through temperature control.

[0070] When processing high-temperature gas or low-temperature environment, the temperature control pipeline 172 can prevent the gas from condensing in the gas washing bottle 17, avoid the condensate water from mixing with the solution to change the concentration of the solution, or cause the pipeline to be blocked due to condensation, and ensure the smooth progress of gas transmission and reaction.

[0071] The different gas inlet channels are connected together by the tee joint, and the mutual penetration of the materials themselves can achieve the purpose of mixing. However, this mixing method has low efficiency and poor mixing effect, so in an embodiment of the present application, the material evaluation device 1 can further include a gas mixing tank 19 installed between the first tee joint 13 and the gas reactor 10. The gas mixing tank 19 includes a stirrer for mixing the gas in different gas inlet channels and introducing the mixed gas into the gas reactor 10.

[0072] In the past, the gas was mixed by relying on the penetration of the materials themselves, which was inefficient. The stirrer in the gas mixing tank 19 can actively stir the gas from different gas inlet channels. The strong power generated by the high-speed rotation of the stirrer promotes the rapid and sufficient contact between gas molecules, greatly shortening the time required for gas mixing. For example, in the scenario of needing to quickly obtain uniformly mixed gas for continuous experiments, the stirrer can quickly complete the gas mixing work, improving the overall efficiency of the experiment.

[0073] In addition to improving efficiency, the stirrer continuously stirs in the gas mixing tank 19, which can uniformly disperse different gases and avoid local over-concentration or under-concentration, ensuring that the mixed gas entering the gas reactor 10 is uniform and stable in composition.

[0074] The arrangement of the gas mixing tank 19 and the stirrer enables the material evaluation device 1 to adapt to more types of gas mixing requirements. Whether it is a high-viscosity gas, a gas with large differences in reaction activity, or a special gas with extremely high mixing uniformity requirements, the stirrer can achieve good mixing, broaden the application range of the device, and improve its applicability in different experimental and industrial scenarios.

[0075] After being fully mixed in the gas mixing tank 19, the gas enters the gas reactor 10 to participate in the reaction, and different reactions often have specific requirements for the temperature of the gas. The previous device has solved the problem of gas mixing. In order to meet the precise control of the temperature of the gas for subsequent reactions and ensure that the mixed gas can enter the gas reactor 10 in the appropriate state, the material evaluation device 1 can further include a vaporization furnace 20 installed between the gas mixing tank 19 and the gas reactor 10. The vaporization furnace 20 is used to heat the mixed gas to a target temperature.

[0076] Precise control of the reaction temperature ensures that the reaction is carried out under optimal temperature conditions, improving the reaction rate and conversion rate. The device can simulate reactions under different temperature environments, expanding the scope of experimental research. Stable gas temperature helps maintain the stability of the reaction and reduces experimental errors caused by temperature fluctuations.

[0077] In one embodiment, the material evaluation device 1 can also include a xenon light source 14 fixed opposite the gas reactor 10, which is used to provide light to the gas in the gas reactor 10.

[0078] Some catalytic reactions require specific wavelengths and energies of light to initiate or accelerate. Xenon lamps can emit strong continuous spectrum light with a wide spectral range, including various wavelengths of light from ultraviolet to near-infrared. In the gas reactor 10, these lights can provide additional energy to the catalyst and reaction gas, making the catalyst more active, thereby reducing the activation energy of the reaction, accelerating the reaction rate, and promoting the occurrence of specific chemical reactions.

[0079] To accommodate the xenon lamp, the gas reactor 10 can be adapted to use a portion of light-transmitting material as the shell of the gas reactor 10, so that the light of the xenon lamp can more easily enter the gas reactor 10.

[0080] At the same time, a light shield 28 can be provided to reduce the probability of light leakage from the xenon light source 14 and to reduce the entry of stray light into the interior of the gas reactor 10.

[0081] After the gas completes the reaction in the gas reactor 10, various products and possibly residual catalysts and other substances will be produced. Therefore, in one embodiment, the material evaluation device 1 can also include a filter 21, a second three-way valve 22, a back pressure valve 23, and a second detection port 24.

[0082] The filter 21 is used to filter the catalyst from the gas reactor 10. The second three-way valve 22 is used to simultaneously connect the outlet of the gas reactor 10, the first detection port 15, and the filter 21. The first detection port 15 is connected to the outlet of the gas reactor 10 through the second three-way valve 22. The back pressure valve 23 is used to control the internal pressure of the gas reactor 10. The second detection port 24 is connected to the filter 21 through the back pressure valve 23, and is used to connect a chromatograph or for emptying.

[0083] The filter 21 effectively separates the catalyst to prevent it from entering the subsequent detection equipment, ensuring the accuracy of the detection. The second three-way valve 22 flexibly controls the flow of gas, making it convenient for product detection and catalyst recovery. The back pressure valve 23 precisely controls the internal pressure of the gas reactor 10, maintaining the stability of the reaction and ensuring the safety of the experiment. The second detection port 24 connects the chromatograph for accurate analysis of product composition, or is used for emptying to facilitate the cleaning of the gas after the reaction, ensuring the normal operation of the device.

[0084] In one embodiment, the material evaluation device 1 can also include a condenser 25. The condenser 25 is connected between the second three-way joint 22 and the filter 21, and is used to remove moisture from the gas discharged from the gas reactor 10.

[0085] In the gas treatment process after the reaction, the gas may contain moisture after being split through the second three-way joint 22, which will affect the subsequent detection and product recovery, etc. The pressure control, composition detection, etc. have been introduced before. Now the condenser 25 is added to further optimize the gas treatment process and ensure that the gas entering the subsequent link meets the requirements.

[0086] The gas in the first detection port 15 is not subjected to other operations, and can directly reflect the cost of the gas generated in the gas reactor 10. The gas in the second detection port 24 can be subjected to operations such as filtering and condensing through the filter 21 and the condenser 25, etc. Compared with the gas in the first detection port 15, it can be more convenient for quantitative analysis.

[0087] The untreated raw gas composition and properties are closest to the state when the reaction is generated. By directly analyzing it, the factors related to the cost such as the raw material input, reaction conditions, etc. required to generate these gases can be clearly understood.

[0088] The treated gas is more convenient for quantitative analysis. During the quantitative analysis process, impurities and moisture and other factors will seriously interfere with the accuracy of the test results. By removing solid particles and other impurities through the filter 21 and removing volatile components such as water vapor through the condenser 25, the gas composition can be made more pure and stable, thereby improving the accuracy of quantitative analysis.

[0089] Both the first detection port 15 can quickly understand the cost-related information of gas generation, and the second detection port 24 can obtain accurate quantitative data of gas composition. This synergistic effect helps to better understand the gas reaction process.

[0090] In addition to the above, the present application also adds other accessories in many pipelines to further enhance the function of the device.

[0091] As shown in Figure 6 In the present application, the number of gas inlet channels can be 2 or more, and 5 is shown as an example in the figure. In each different gas inlet channel, a filter structure can be provided, such as F-111, F112, F113, F-114, F115, etc. in Figure 6 , which is used to preliminarily filter the gas inlet.

[0092] At the same time, the intake passage can also be provided with a straight-through ball valve for controlling the on-off of the gas and adjusting the flow rate. BV-111, BV112, BV113, BV-114, BV115 in the figure are such straight-through ball valves.

[0093] In addition, one-way valves such as CV-111, CV112, CV113, CV-114, CV115, etc. can ensure that the gas can only pass in one direction. When abnormal situations such as system pressure fluctuations, equipment failures, etc. cause a tendency for the gas flow to flow in the opposite direction, the one-way valve will quickly close to prevent the reverse flow of gas, thereby protecting other components in the system from the impact and damage of reverse flow gas, and avoiding possible problems such as gas backflow and pollution.

[0094] Temperature controllers (TIC) and temperature measuring elements (TE) can also be installed before the gas mixing tank 19, between the vaporization furnace 20 and the gas reactor 10, at the vaporization furnace 20, and at the gas reactor 10.

[0095] In addition, a third detection port can also be introduced between the vaporization furnace 20 and the gas reactor 10.

[0096] The installed third detection port can be used to lead out the gas before the gas reactor 10, and the gas that has not passed through the gas reactor 10 can be used as a control group, providing a basis for the accuracy of subsequent gas analysis.

[0097] Any detection port can be equipped with a needle valve, such as NV-111, NV-112, NV-113 in the figure. The needle valve can precisely fine-tune the gas flow of the detection port. When detecting the composition of the gas, according to the requirements of the detection instrument, the gas flow into the detection instrument is precisely controlled to ensure the accuracy and stability of the detection data. Secondly, the needle valve can effectively control the gas pressure of the detection port. When the gas pressure has strict requirements for the equipment such as chromatograph connected to the detection port, the needle valve can adjust the gas to enter the equipment at an appropriate pressure, preventing the detection results from being affected by excessive or insufficient pressure, and also protecting the detection equipment and prolonging the service life of the equipment. Thirdly, during the gas emptying operation, the needle valve can slowly open and close to avoid the impact and noise caused by the rapid discharge of gas, making the emptying process more stable and safe.

[0098] In any embodiment of the present application, the material evaluation device 1 can also include a combustible gas alarm 27

[0099] The combustible gas alarm 27, as part of the material evaluation device 1, can monitor the combustible gas concentration in the reaction chamber and the surrounding environment in real time. It is independent of the reaction structure of the gas reactor 10, but closely cooperates with it, and always pays attention to the gas safety condition of the entire experimental space.

[0100] In the material research experiment, many reactions involve the use of combustible gas or may produce combustible gas byproducts. For example, in the reaction process of some organic materials and specific gases, combustible volatile organic compounds may be generated due to incomplete reaction or condition fluctuation. The combustible gas alarm 27 can timely issue a warning when the combustible gas concentration reaches a dangerous threshold, reminding the experimental personnel to take corresponding measures such as ventilation, stopping the reaction, etc., effectively avoiding serious safety accidents such as explosion or fire caused by the accumulation of combustible gas, and providing solid protection for the personal safety of the experimental personnel and the safe operation of the experimental equipment.

[0101] The material evaluation device 1 with the gas inlet structure according to the embodiment of the present application has the following beneficial effects compared with the prior art:

[0102] The reaction cavity is composed of a kettle body 101 and a kettle cover 102. The gas inlet end 104 can introduce external gas into the reaction cavity, and the gas outlet end 105 can discharge the gas in the reaction cavity. At the same time, the detection system composed of the metal probe 106, the signal line 107 and the electronic detector is always in working state. During the reaction of the material and the gas, with the introduction of the gas and the progress of the reaction, the electronic detector can synchronously monitor the dynamic change of the electrical properties of the material through the metal probe 106 and the signal line 107. This solves the problem that the traditional gas analyzer cannot synchronously monitor the gas reaction process and the change of the electrical properties of the material in real time, and helps to deeply study the mechanism of the interaction between the material and the gas, and provides a key means for accurately grasping the reaction process and the evolution of the material properties.

[0103] In summary, the material evaluation device 1 according to the embodiment of the present application integrates a plurality of key components including the gas inlet structure, the mass flow controller 16, the gas washing bottle 17, the four-way ball valve 18, the gas mixing tank 19, the vaporization furnace 20, the xenon light source 14, the filter 21, the second three-way 22, the back pressure valve 23, the second detection port 24, the condenser 25, etc. Through reasonable structural design and collaborative work of the components, the whole process fine control of the gas from the gas inlet, mixing, reaction condition control to the treatment and detection of the reaction products is realized.

[0104] From the perspective of gas mixing, the gas mixing tank 19 is matched with the stirrer to improve the mixing efficiency and effect; in terms of reaction condition control, the vaporization furnace 20 accurately controls the temperature, and the xenon light source 14 provides illumination conditions to meet the needs of different types of reactions; in the treatment link after the reaction, the filter 21 separates the catalyst, the condenser 25 removes moisture, the back pressure valve 23 controls the pressure, and the second detection port 24 cooperates with the first detection port 15 to realize the detection of product composition and gas emptying.

[0105] Overall, the material evaluation device 1 greatly improves the accuracy, repeatability and efficiency of the experiment, expands the depth and breadth of the research on gas materials and reactions, and provides a powerful and reliable experimental tool for related scientific research and industrial applications.

[0106] The above merely preferred embodiments of the present application, it should be noted that for those of ordinary skill in the art, without departing from the technical principles of the present application, can make several improvements and replacements, these improvements and replacements should also be considered as the protection scope of the present application.
