Description

Technical Field

[0001] The present invention specifically provides a dynamic tracking adsorption testing device and method that is adaptable to the adsorption performance of adsorbents with different carbon dioxide partial pressures in multiple scenarios. Background Art

[0002] With the rapid advancement of materials science, porous carbon capture materials have become a popular material. Demand for testing their adsorption properties is increasing, and equipment and technology are maturing. However, some shortcomings remain. For example, material pretreatment is insufficient: most equipment cannot achieve vacuum and high-temperature activation; detection is limited: relying on a single gas concentration sensor makes it difficult to determine the adsorption saturation point; and applicability is limited: traditional reactors are sensitive to sample morphology and are incompatible with bulk or heterogeneous materials. This incompatibility is primarily due to the reactor's design principles, operating conditions, and the inherent properties of the bulk or heterogeneous materials. This is primarily due to the fact that in homogeneous reactions, the reactants are in the same phase, eliminating interphase contact. In heterogeneous reactions, the reactants are in different phases, requiring consideration of interphase contact area and contact efficiency. Homogeneous reactors do not require interphase contact considerations, making their design relatively simple. Heterogeneous reactors, however, must ensure good interphase contact and are generally more complex to design. For example, gas-liquid reactors must address mixing and heat transfer between the gas and liquid phases.

[0003] However, bulk materials have large sizes and fixed shapes, which limit their fluidity and mixing properties in the reactor. There may be obstacles to heat and mass transfer inside the bulk materials, resulting in reduced reaction efficiency. In the reactor, bulk materials may form "hot spots" or "cold spots", affecting the uniformity and stability of the reaction. In addition, bulk materials may block the reactor pipes or stirring devices, causing operational difficulties. During long-term reactions, bulk materials may produce fragments due to wear, affecting the normal operation of the reactor. The composition and properties of non-uniform materials vary spatially, which may lead to non-uniformity and instability during the reaction process. Due to the differences in the composition and properties of non-uniform materials, the reaction rate and selectivity may vary in different locations, affecting the quality of the product. The reaction process of non-uniform materials is difficult to accurately predict and control, which increases the uncertainty and risk of production. In short, the reactor is incompatible with bulk or non-uniform materials mainly because these materials have limitations in the design principles, operating conditions and properties of the reactor itself. To ensure proper reactor operation and stable product quality, homogeneous materials are typically used or special mixing and heat transfer measures are implemented in heterogeneous reactions. Furthermore, the lack of an exhaust gas analysis module prevents a closed-loop data loop for the entire process. In short, there is no comprehensive approach to measuring the adsorption capacity and cycle stability of gases like carbon dioxide over a wide temperature range. Current devices are unable to dynamically track the adsorption process, and standardized processing equipment and methods for multi-parameter linkage analysis are lacking. Summary of the Invention

[0009] A dynamic tracking adsorption test method that is suitable for the adsorption performance of adsorbents with different carbon dioxide partial pressures in multiple scenarios is implemented using the above-mentioned dynamic tracking adsorption test device that is suitable for the adsorption performance of adsorbents with different carbon dioxide partial pressures in multiple scenarios. The dynamic tracking adsorption test method is to subject the test sample to vacuum activation pretreatment and then adsorption and desorption to obtain the mass change and import and export concentration data of the adsorption stage, establish a triple adsorption amount calculation model based on the mass change and import and export concentration data of the adsorption stage, and complete the adsorption cycle stability test process according to the triple adsorption amount calculation model after data analysis.

[0010] As a preferred solution: the test sample is inspected before vacuum activation pretreatment, and the inspection operation is to check the sealing performance and connection status of the reaction master control, the self-regulating gas supply system and the gas analysis system.

[0011] As a preferred solution: the process of subjecting the test sample to vacuum activation pretreatment is as follows: placing the test sample in a porcelain boat, ensuring that the test sample is evenly distributed in the porcelain boat with a thickness of 1 to 5 mm; placing the porcelain boat containing the test sample on a weight sensor in a vacuum tube furnace, ensuring that the porcelain boat and the weight sensor are on the same vertical central axis; closing the entrance of the vacuum tube furnace to ensure that the interior of the vacuum tube furnace is in a sealed state, then closing the three-way valve, starting the vacuum pump, and using the vacuum pump to ensure that the vacuum state inside the vacuum tube furnace reaches the predetermined requirements, then starting the vacuum tube furnace heating function to perform the vacuum activation treatment process; after the vacuum activation treatment process is completed, closing the three-way valve connected to the vacuum pump, and starting the gas analyzer to perform a test adsorption process for removing impurity gases adsorbed by the adsorbent in the early stage.

[0012] As a preferred solution, the process of obtaining the mass change and inlet and outlet concentration data of the test sample after vacuum activation pretreatment, adsorption, and desorption is as follows: Adsorption process: First, open the first valve at the inert gas supply bottle and the second valve at the test gas supply bottle, ensure that the inert gas supply bottle is connected to the vacuum tube furnace through the first vent pipe, and the test gas supply bottle is connected to the gas storage tank through the second vent pipe, adjust the weight sensor reading to zero, adjust the first mass flow controller according to the predetermined gas partial pressure requirement, and mix the gas at a flow rate of 0.1~0.5L / min in the corresponding proportion to form a mixed gas, which is then introduced into the gas storage tank; when there is a corresponding requirement to adjust the gas humidity in the predetermined requirement, turn on the humidity generator accordingly, and adjust the first mass flow controller to control the flow rate of saturated water vapor entering the gas storage tank to meet the predetermined requirement; when ensuring that the corresponding values ​​of the gas concentration detector and the humidity sensor meet the predetermined requirements, open the fourth valve to allow the gas flow in the gas storage tank to flow into the vacuum tube furnace at a flow rate of 0.5~1.0L / min, and after the mixed gas is filled into the vacuum tube furnace, simultaneously observe the reading change range of the weight sensor and the gas analyzer, and complete the adsorption process accompanied by the mixed gas within the predetermined time; The concentration of carbon dioxide gas filled into the vacuum tube furnace is measured by a gas concentration detector, and the concentration of carbon dioxide gas discharged from the vacuum tube furnace is measured by a gas analyzer. The adsorption capacity of the adsorbent is calculated based on the change in the carbon dioxide concentration in the inlet and outlet gases. When the weight sensor reading is stable and the gas concentration before and after the vacuum tube furnace test is consistent, it indicates that the adsorption capacity has reached a saturated state, that is, the test sample has reached the maximum adsorption capacity state; when the carbon dioxide concentration discharged from the vacuum tube furnace is 5% of the carbon dioxide concentration filled into the vacuum tube furnace, the carbon dioxide adsorption capacity of the test sample at this time is the breakthrough adsorption capacity; Desorption process: Open the first valve and the sixth valve at the same time, close the gas storage tank, and after the reading on the gas analyzer is zero, stabilize the flow rate of the inert gas supply bottle at 0.1~0.5L / min. Set the time and temperature corresponding to the desorption reaction according to the test requirements, start the vacuum tube furnace for heating, and obtain the real-time carbon dioxide content data displayed by the gas analyzer through the computer acquisition system and record it until the value returns to 0 and remains unchanged for a predetermined period of time, indicating that the desorption reaction is complete; Data analysis process: Based on the mass change in the adsorption stage and the integrated data of the import and export concentrations, a triple adsorption calculation model was established ( q 1. q 2. q 3), the corresponding formulas are Formula 1, Formula 2 and Formula 3: Formula 1 In the above formula, q1 is the gas adsorption amount measured in the adsorption stage, the unit is cm 3 / g; w is the weight of the adsorbent material, in g; t0 and t1 are the start and end times of the desorption display of the adsorbent material, in min; Q is the fixed flow rate during inert gas purge, in mL / min; C is the real-time reading of the gas analyzer at the outlet of the tube furnace, in %, C0 is the reading of the gas concentration tester at the inlet of the tube furnace, in %, V m is the gas molar volume of the adsorbed gas, in mL / mmol; Formula 2 In the above formula, q2 is the gas adsorption amount measured in the desorption stage, in cm 3 / g, w is the weight of the adsorbent material, in g, t0 and t1 are the start and end times of the desorption of the adsorbent material, in min, and Q is the fixed flow rate of the inert gas during purging, in mL / min; C t It is the real-time reading of the gas analyzer, in units of %; V m is the gas molar volume of the adsorbed gas, in mL / mmol; Formula 3 In the above formula, q3 is the gas adsorption amount measured in the adsorption stage, the unit is cm 3 / g; w is the weight of the adsorbent material, in g; ∆G is the change in reading before and after the weight sensor, in g; M is the molar mass of carbon dioxide, in g / mol; Based on three calculation models, until the final result is achieved When , it indicates that the acquired data is reliable and can be used for subsequent use.

[0013] As a preferred solution: the adsorption cycle stability test process is carried out according to the triple adsorption capacity calculation model after data analysis: after completing the adsorption experiment, open the first valve and the sixth valve at the same time, pass the inert gas through the vacuum tube furnace at a predetermined flow rate of 0.1~0.5L / min, set the temperature and time, and the desorption reaction begins. Observe the carbon dioxide concentration reading of the gas analyzer. After the value appears at the beginning and returns to 0 and remains unchanged for a predetermined time, it indicates that the desorption reaction has ended; at this time, after the temperature of the tube furnace is reduced to the adsorption temperature, open the second valve and close the sixth valve at the same time, adjust the flow rate according to the established gas partial pressure to pass into the gas storage tank, so that a mixed gas with a predetermined carbon dioxide concentration flows in, and the adsorption reaction begins. Repeat the above steps, and the cyclic stability of the adsorbent can be judged by the change in adsorption capacity with the number of times. When the adsorption capacity remains unchanged or slowly decreases with the increase in the number of times, the decrease does not exceed 10%, indicating that the cyclic stability of the adsorbent is in good condition. When the adsorption capacity decreases rapidly with the increase in the number of times and drops to 0 after at least three cycles, it indicates that the cyclic stability of the adsorbent is in failure.

[0014] As a preferred solution: when the adsorption capacity disappears to 0 within a few seconds as the number of times increases, it also indicates that the cyclic stability of the adsorbent is in a failure state.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The dynamic tracking adsorption test device for the different carbon dioxide partial pressure adsorption performance of the multi-scenario adsorbent in the present invention is constructed by the cooperation between the reaction master control, the gas analysis system and the inert gas supply cylinder, the test gas supply cylinder, the adsorption gas supply cylinder, the gas storage tank, the gas concentration detector, the humidity generator, the first mass flow controller and the humidity sensor in the self-regulating gas supply system to construct a set of high-precision, multi-scenario adaptive adsorption performance detection system, which can test the adsorption performance, desorption performance and cyclic stability of the solid adsorbent under different gas partial pressures, flow rates, humidity and temperature conditions, forming a continuous and accurate acquisition process of the three properties. The present invention can realize cross-validation of adsorption capacity through mass-concentration dual-mode sensing, providing comprehensive data support for material optimization and engineering applications.

[0016] The dynamic tracking adsorption test method adapted to the adsorption performance of adsorbents with different carbon dioxide partial pressures in multiple scenarios in the present invention can provide a more comprehensive, efficient and economical solution for testing the gas adsorption capacity of materials. By integrating the vacuum activation system, a standardized and continuous processing process can be formed, the vacuum high-temperature activation process can be completed in a standardized manner, and the measurement deviation caused by impurities adsorbed on the surface of the material can be removed. Through the mutual cooperation between the vacuum tube furnace, weight sensor, porcelain boat, gas analysis system and self-regulating gas supply system, the dynamic response of material quality changes and gas concentration can be monitored synchronously; the adsorption amount, adsorption rate and other data can be obtained through the flow meter and gas analyzer, and the adsorption efficiency can be accurately calculated, providing dynamic tracking adsorption test guidance for the standardized processing of the adsorption performance process of adsorbents with different carbon dioxide partial pressures in multiple scenarios.

After the mixed gas is filled into the vacuum tube furnace 1-3, the reading change range of the weight sensor 1-1 and the gas analyzer 14 is simultaneously observed, and the adsorption process accompanied by the mixed gas is completed within the predetermined time; The concentration of carbon dioxide gas filled into the vacuum tube furnace 1-3 is measured by a gas concentration detector 2-5, and the concentration of carbon dioxide gas discharged from the vacuum tube furnace 1-3 is measured by a gas analyzer 14. The adsorption capacity of the adsorbent is calculated based on the change in the carbon dioxide concentration in the inlet and outlet gases. When the reading of the weight sensor 1-1 is stable and the gas concentration before and after the test of the vacuum tube furnace 1-3 is consistent, it indicates that the adsorption capacity has reached a saturated state, that is, the test sample has reached a maximum adsorption capacity state; when the concentration of carbon dioxide discharged from the vacuum tube furnace 1-3 is 5% of the concentration of carbon dioxide filled into the vacuum tube furnace 1-3, it means that the carbon dioxide adsorption capacity of the test sample at this time is a breakthrough adsorption capacity; Desorption process: Open the first valve 9 and the sixth valve 20 at the same time, close the gas storage tank 2-4, and stabilize the flow rate of the gas supplied by the inert gas supply bottle 2-1 at 0.1~0.5L / min when the reading of the gas analyzer 14 is zero. Then set the time and temperature corresponding to the desorption reaction according to the test requirements, start the vacuum tube furnace 1-3 for heating, and the computer acquisition system 15 obtains the real-time carbon dioxide content data displayed by the gas analyzer 14 and records it until the value changes from the beginning to zero and remains unchanged for a predetermined period of time, indicating that the desorption reaction is completed; Among them, according to the test requirements, the corresponding desorption reaction time is set to 60 minutes, and the corresponding desorption reaction temperature is set to 130° C. The time and temperature can be determined according to the specific desorption requirements.

[0038] Data analysis process: Based on the mass change in the adsorption stage and the integrated data of the import and export concentrations, a triple adsorption calculation model was established q 1.q 2. q 3, the corresponding formulas are Formula 1, Formula 2 and Formula 3: Formula 1 In the above formula, q1 is the gas adsorption amount measured in the adsorption stage, the unit is cm 3 / g; w is the weight of the adsorption material, in g; t0 and t1 are the start and end times of the desorption of the adsorption material, in min; Q is the fixed flow rate of the inert gas during purging, in mL / min; C is the real-time reading of the gas analyzer 14 at the outlet of the tube furnace, in %, C0 is the reading of the gas concentration tester at the inlet of the tube furnace, in %, V m is the gas molar volume of the adsorbed gas, in mL / mmol; Formula 2 In the above formula, q2 is the gas adsorption amount measured in the desorption stage, in cm 3 / g, w is the weight of the adsorbent material, in g, t0 and t1 are the start and end times of the desorption of the adsorbent material, in min, and Q is the fixed flow rate of the inert gas during purging, in mL / min; C t It is the real-time reading of the gas analyzer 14, in units of %; V m is the gas molar volume of the adsorbed gas, in mL / mmol; Formula 3 In the above formula, q3 is the gas adsorption amount measured in the adsorption stage, the unit is cm 3 / g; w is the weight of the adsorbent material, in g; ∆G is the change in the reading of the weight sensor 1-1 before and after, in g; M is the molar mass of carbon dioxide, in g / mol; Based on three calculation models, until the final result is achieved When , it indicates that the acquired data is reliable and can be used for subsequent use.

[0039] Specific embodiment nine: This embodiment further limits specific embodiments five, six, seven, or eight. In this embodiment, the adsorption cycle stability test process is conducted based on a triple adsorption capacity calculation model after data analysis. After the adsorption experiment is completed, the first valve 9 and the sixth valve 20 are opened simultaneously, and an inert gas is passed through the vacuum tube furnace 1-3 at a predetermined flow rate of 0.1 to 0.5 L / min. The temperature and time are set, and the desorption reaction begins. The carbon dioxide concentration reading on the gas analyzer 14 is observed. After the value initially appears and returns to zero and remains unchanged for a predetermined time, it indicates that the desorption reaction has ended. At this time, after the tube furnace temperature is lowered to the adsorption temperature, the second valve 10 is opened while the sixth valve 20 is closed. The flow rate is adjusted according to the predetermined gas partial pressure to pass into the gas storage tank 2-4, so that a mixed gas with a predetermined carbon dioxide concentration flows in, and the adsorption reaction begins. Repeat the above steps and the cyclic stability of the adsorbent can be determined by the change in adsorption capacity with the number of times. When the adsorption capacity remains unchanged or slowly decreases with the increase in the number of times and the decrease does not exceed 10%, it indicates that the cyclic stability of the adsorbent is in good condition. When the adsorption capacity decreases rapidly with the increase in the number of times and drops to 0 after at least three cycles, it indicates that the cyclic stability of the adsorbent is in a failed state.

[0040] Another way to determine whether the cyclic stability of the adsorbent is in a failed state in this embodiment is that when the adsorption capacity disappears to 0 within a few seconds as the number of times increases, it also indicates that the cyclic stability of the adsorbent is in a failed state.

[0041] Specific embodiment ten: This embodiment is a further limitation of specific embodiments five, six, seven, eight or nine. In this embodiment, when harmful gases such as CO, CH4, etc. are involved in the process of advancing this method, an exhaust gas treatment device needs to be set at the outlet. The working principle of the exhaust gas treatment device is the same as that of the existing exhaust gas treatment device.
