Description

Technical Field

[0001] The present invention relates to the technical field of tubular reactors, and in particular to a tubular multi-source energy coupled catalytic reactor and system. Background Art

[0002] In the field of catalytic reaction research, gas-solid phase catalytic reactions are one of the most common laboratory catalytic reactions studied. Activity tests for these reactions are typically conducted in fixed-bed reactors. Fixed-bed reactors typically utilize a high-temperature, electrically heated furnace equipped with a programmable temperature controller. The furnace is used to ensure the high reaction temperature required, while the programmable temperature controller allows for convenient, real-time adjustment of the reaction temperature based on the reaction requirements.

[0003] In recent years, a large number of studies have found that due to the synergistic effect of light and heat, when light sources are introduced into the thermal catalytic process, many reactions exhibit different phenomena, characteristics, and mechanisms that are different from those of thermal catalysis.

[0004] When reactions occur in existing catalytic tubular reactors, the energy utilization rate of light and heat is low. Due to different spatial distribution and energy transfer methods, the coupling loss of light and heat is relatively large. At the same time, due to the limited light penetration ability, the effect is relatively weak for large-scale reactions or reaction systems with low light absorption rates. Summary of the Invention

The second flange is provided with an exhaust port to form a vacuum insulation layer between the inner tube and the outer tube. The two ends of the pull rod are fixed on the second flange.

[0014] The present application also provides a tubular multi-source energy coupling catalytic system, which uses any of the tubular multi-source energy coupling catalytic reactors described above and also includes a columnar light source, a temperature-sensitive heating tube, a radio frequency transmitting device, and an absorbing material. The columnar light source is arranged on the pull rod, the position of the light-transmitting hole corresponds to the position of the columnar light source, and multiple light-transmitting holes can be provided.

[0015] The technical solution provided in this application document has the following beneficial effects:

[0016] The present invention provides a tubular multi-source energy coupling catalytic reactor and system. The reactor includes a transparent inner tube and outer tube, a first flange, a second flange, a radio frequency feed port, an inner sleeve, and a metal pull rod. The first flange and the second flange are respectively installed at the two ends of the inner tube and the outer tube to form a reaction space.

[0017] To facilitate illumination, a metal reflective surface is provided on the inner circumference of the outer tube. The metal reflective surface can also be provided in the space enclosed by the outer tube and the inner tube. A light-transmitting hole or light-transmitting window is provided on the metal reflective surface, so that light can pass through the light-transmitting hole or light-transmitting window to form a uniform light spot inside the inner tube.

[0031] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0032] This embodiment provides a tubular multi-source energy coupling catalytic reactor and system, which solves the technical problems of large energy loss, low energy utilization and long heating process time in the existing catalytic tubular reactor.

[0033] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the invention as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the invention as set forth in the claims.

[0034] Reference Figures 1-8 The present invention provides a tubular multi-source energy coupling catalytic reactor, comprising a transparent inner tube 10, a transparent outer tube 11, a first flange 1, a second flange 2, a radio frequency feed port 9, an inner sleeve 8, and a metal tie rod 3. The first flange 1 is mounted at both ends of the inner tube 10 to seal the inner tube 10, and the second flange 2 is mounted at both ends of the outer tube 11 to seal the outer tube 11. The ends of the inner tube 10 extend beyond the ends of the outer tube 11. Tie rods 3 are evenly arranged around the outer circumference of the outer tube 11, and the ends of the tie rods 3 are fixed to the second flange 2, i.e., the two second flanges 2 are arranged between the two first flanges 1. The inner tube 10 is used to place materials, and a certain distance exists between the outer wall of the inner tube 10 and the inner wall of the outer tube 11 to facilitate the formation of a vacuum. To facilitate the placement of materials, a material inlet 5 is provided on one of the first flanges 1, and a material outlet 7 is provided on the other first flange 1. Thus, the material enters the inner tube 10 from the material inlet 5 for reaction, and after the reaction is completed, the material is discharged from the material outlet 7.

[0035] To facilitate illumination, the inner circumference of the outer tube 11 is further provided with a metal reflective surface 20. The metal reflective surface 20 can also be provided in the space enclosed by the outer tube 11 and the inner tube 10. The metal reflective surface 20 is provided with a light-transmitting hole 21 or a light-transmitting window, so that light can pass through the light-transmitting hole 21 or the light-transmitting window to form a uniform light spot in the inner tube 10. The position of the light-transmitting hole 21 or the light-transmitting window corresponds to the position of the pull rod 3. The metal reflective surface 20 has three functions: (1) RF shielding to prevent RF from diffusing outward while reflecting RF into the inner tube 10; (2) reflecting infrared heat radiation to reduce energy consumption; and (3) reflecting secondary light to improve light efficiency. The material of the metal reflective surface 20 can be, but is not limited to, a mirror coating or mirror aluminum.

[0036] In order to increase the reaction speed, the RF feed port 9 is installed on the first flange 1 or the second flange 2 for installing the RF transmitting antenna 16; the first flange 1 is provided with an inner sleeve 8, which extends into the space of the inner tube 10 to facilitate installation for detecting temperature or providing heat energy. In this way, when the inner sleeve 8 can provide heat energy, the heat energy can be directly supplied to the inner tube 10. When used for temperature detection, the temperature in the inner tube 10 can be directly transferred to the inner sleeve 8, facilitating the exchange of heat energy.

[0037] In addition, an exhaust port 6 is provided on the second flange 2, and the space enclosed by the inner tube 10 and the outer tube 11 is connected to the exhaust port 6. In this way, people can evacuate the space enclosed by the inner tube 10 and the outer tube 11 to form a vacuum insulation layer 15, so that the heat energy is concentrated around the inner tube 10, reducing the diffusion of heat. At the same time, when high pressure is formed, in order to ensure the stability of the vacuum insulation layer 15, the pull rod 3 can ensure the stability of the pressure in the vacuum, avoid the outer tube 11 from moving toward each other under pressure, and ensure the safety of the experiment, wherein the number of pull rods 3 is three or more.

[0038] With this setup, people can choose different energy sources according to the requirements of the experiment, and can realize independent operation of light, heat, and radio frequency, as well as catalytic reaction systems such as light-heat, light-radio frequency, and light-heat-radio frequency coupling.

[0039] To further optimize the solution, in order to facilitate the feeding of radio frequency, the radio frequency feed port 9 is installed in the middle position of the first flange 1, so that the radio frequency can be injected into the inner tube 10, or the radio frequency feed port 9 is evenly arranged on the end face of the second flange 2 along the circumference of the first flange 1, and the radio frequency can penetrate the transparent inner tube 10, so that the radio frequency can be indirectly injected into the inner tube 10. In order to ensure the energy of the radio frequency, multiple radio frequency feed ports 9 are arranged circumferentially. With this arrangement, the position of the radio frequency feed port 9 can be selected according to actual conditions, which is convenient for people to use.

[0040] To further optimize the solution, in order to ensure the airtightness of the inner tube 10 and the outer tube 11, a second sealing ring 13 is designed between the inner tube 10 and the first flange 1, and a first sealing ring 12 is designed between the outer tube 11 and the second flange 2 to form a closed space.

[0041] In the prior art, metal tubes are required when reactors are used at high temperatures and high pressures. However, in certain catalytic reactions, such as hydrogenation / dehydrogenation reactions, oxidation reactions, and reforming reactions, the reaction gases may, under certain conditions, have a catalytic effect on the metal reactor, resulting in coking or contamination of the reactor, and even affecting the analysis of the reaction results.

[0042] In the present application, the inner tube 10 and the outer tube 11 are both made of inert materials, which may be quartz glass, sapphire, etc., which can prevent the inner tube 10 from coking or being contaminated, and avoid reacting with the material.

[0043] As a further optimization solution, an observation window is provided on the metal reflective surface 20, so that people can observe the reaction inside the inner tube conveniently.

[0044] The present application provides a tubular multi-source energy coupling catalytic system. Using any of the above-mentioned tubular multi-source energy coupling catalytic reactors, people can perform coupling according to the situation. There are many ways of coupling, including light-heat coupling, light-radio frequency coupling, light-heat-radio frequency coupling catalytic reaction system, etc.

[0045] When the reaction system is optical-radio frequency coupled, it also includes a cylindrical light source 17, a radio frequency transmitter, a temperature probe 19, and an absorbing material 14. The cylindrical light source 17 is arranged on the pull rod 3. The position of the light-transmitting hole 21 or the light-transmitting window corresponds to the position of the cylindrical light source 17, and multiple light sources can be provided. Since the pull rod 3 is arranged along the circumference of the outer tube 11, it is convenient to form a surround-type light source. At the same time, when people use it, they can flexibly adapt to different forms of light source modules without making special structural requirements for the reactor body. The radio frequency transmitter is installed in the radio frequency feed port 9, the absorbing material is placed in the inner tube 10, and the temperature probe 19 is inserted into the inner sleeve 8. The temperature probe 19 is a special thermal probe for the radio frequency field, which is used to accurately detect the temperature changes in the reaction zone in real time to ensure the study of the catalytic reaction mechanism and the evaluation of catalyst performance.

[0046] Among them, the columnar light source 17 is installed on the pull rod 3. The columnar light source 17 can be (1) LED + cylindrical mirror (different wavelengths or a certain range of waves can be set); (2) long tubular mercury lamp + reflector + cylindrical mirror (low-pressure mercury lamp or medium-pressure mercury lamp can be used); (3) long arc xenon lamp + reflector + cylindrical mirror; (4) line convergence laser light source, but the columnar light source 17 is not limited to these forms, and other light sources can be selected according to actual conditions. Since the inner circumference of the outer tube 11 is also provided with a metal reflective surface 20, and the metal reflective surface 20 is provided with a light-transmitting hole 21 or a light-transmitting window, the position of the light-transmitting hole 21 or the light-transmitting window corresponds to the position of the columnar light source 17. According to the principle of pinhole imaging, the light emitted by the cylindrical light source 17 forms a light spot through the light-transmitting hole 21 or the light-transmitting window. Since the light-transmitting hole 21 or the light-transmitting window is evenly arranged at a position on the metal reflective surface 20, a uniform light spot is formed, avoiding the use of a filter, thereby achieving continuous adjustment of the light distribution, which can match the absorption and reaction needs of different catalysts.

[0047] The RF transmitter is mounted at the RF feed port 9. The RF generated by the RF generator (RF source) is transmitted via a coaxial cable to the reactor's RF feed port. The RF is then efficiently transmitted to the reaction zone through a simulated port connection design. The RF source can be a magnetron or a solid-state RF source. An absorbing material 14 is provided within the inner tube 10 to absorb RF energy and increase the temperature within the inner tube 10. RF not only polarizes molecules, intensifying molecular motion and collisions, and promoting reactions at a microscopic level, but also alters the activation energy and reaction path, thereby increasing reaction selectivity, favoring the production of target products and minimizing the generation of byproducts. This method also offers advantages for substances with unique dielectric properties, offering broad application prospects in materials synthesis, organic reactions, and other fields.

[0048] In this way, the light-RF coupled catalytic reaction system is constructed and applied to the photocatalytic system to introduce RF energy to achieve light-RF synergy. Light provides photon energy to excite electrons, and the electromagnetic field of RF can change the distribution of electron clouds on the catalyst surface, promote molecular polarization, and increase the reaction activity of active sites. The light-RF coupled catalytic system provides energy for the reaction, makes full use of energy, and increases the selectivity of the catalytic reaction.

[0049] The present application also provides a tubular multi-source energy coupling catalytic system, which uses any of the above-mentioned tubular multi-source energy coupling catalytic reactors, and also includes a columnar light source 17, a temperature-sensitive heating tube 18, and a catalyst. The columnar light source 17 is arranged on the pull rod 3, and the position of the light-transmitting hole 21 or the light-transmitting window corresponds to the position of the columnar light source 17, and multiple temperature-sensitive heating tubes 18 are provided, which extend into the inner sleeve 8, so that the heat energy can be directly transferred to the inner tube 10, reducing the waste of heat energy.

[0050] The present application also provides a tubular multi-source energy coupling catalytic system, which uses any of the above-mentioned tubular multi-source energy coupling catalytic reactors and also includes a columnar light source 17, a temperature-sensitive heating tube 18, a radio frequency transmitting device, and an absorbing material. The columnar light source 17 is arranged on the pull rod 3, and the position of the light-transmitting hole 21 or the light-transmitting window corresponds to the position of the columnar light source 17, and multiple light-transmitting holes 21 or windows can be provided. The radio frequency transmitting device is installed in the radio frequency feed inlet 9 to provide radio frequency for the reactor, and the temperature-sensitive heating tube 18 extends into the inner sleeve 8 to provide heat energy for the reactor.

[0051] The construction of the photo-thermal-radiofrequency multi-field coupled catalytic system is primarily targeted at the application scenarios of multi-field catalytic coupling. In this multi-field synergistically coupled catalytic system, light provides photon energy to excite electrons, heat intensifies molecular motion and increases reaction rate, and the electromagnetic field of radio frequency changes the electron cloud distribution on the catalyst surface, promoting molecular polarization and increasing the reactivity of active sites. The photo-thermal-radiofrequency multi-field coupled catalytic reaction system supplies energy for the reaction from different pathways, fully utilizing energy and improving overall conversion efficiency.

[0052] Other forms of single-field catalysis and coupled catalysis can be freely combined and selected for operation in this system.

[0053] With this configuration, this application has the following advantages:

[0054] 1. Efficient internal heating: Fast response, rapid temperature rise, and high energy utilization. Conventional reactors utilize heating resistors within the heat-insulating furnace, resulting in large space, high heat capacity, slow heat transfer, and low energy utilization. This new technology avoids the additional energy consumption required by non-reactive systems, accelerates temperature rise and fall rates, improves reaction efficiency and production flexibility, and facilitates intermittent energy utilization.

[0055] 2. Vacuum barrier design: A vacuum barrier isolates the internal reaction temperature from dissipating outward, reducing the reaction system space, increasing the heating and cooling rates, and reducing unnecessary energy consumption. An infrared reflective film coating the inner wall of the vacuum tube (i.e., the outer metal reflective surface) further improves energy utilization.

[0056] 3. Optimized Light Field Coupling: This breakthrough in high-efficiency light field coupling technology utilizes a vacuum-insulated transparent quartz cylinder to achieve light transmission across the entire cylindrical surface. Existing furnace-type photothermal catalytic devices require light to pass through the thick insulation layer of the furnace wall, requiring complex processing such as focusing and transmitting light to the light-emitting device, resulting in significant irradiation power loss. By making the entire cylindrical surface light-transmissive, the present invention overcomes the limitations of the reaction site's light-receiving method, significantly expanding the range of applicable light-emitting devices or irradiation devices. This maximizes thermal and optical energy coupling and spatial coupling, optimizes the matching of the light spot with the catalyst, and improves photon absorption efficiency. Furthermore, it facilitates observation and monitoring of the reaction's internal conditions.

[0057] 4. Rich Light Source Options: A variety of light sources are available, including LEDs, long-tube mercury lamps, long-arc xenon lamps, and linear lasers. Cylindrical mirrors are also used to optimize light irradiation. Pulsed LEDs can also be used to observe reaction fluctuations under specific conditions.

[0058] 5. Multifunctional Heating Device: This device incorporates porous SiC material as a heating element, capable of both resistive heating and radio frequency (RF) modes. RF mode enables rapid heating and synergistic RF and catalytic processes. It can also superimpose external light sources to optimize multi-field reaction models.
