TECHNICAL FIELD
[0001] The present application relates to the technical field of chemical equipment, in particular to a catalyst reactor. BACKGROUND
[0002] Fuel cell is an energy conversion device that can continuously convert chemical energy into electrical energy, which has the advantages of clean and high efficiency, and has important significance for improving the environment and realizing the sustainable development of energy. At present, the hydrogen source required by fuel cells is obtained by hydrogen production from fossil fuels, hydrogen extraction from chemical byproducts, hydrogen production from biological methanol and methane, solar energy, wind energy and other natural energy. However, the storage and transportation of external hydrogen gas have problems such as high cost and great safety hazard, which restricts the supply of hydrogen source for fuel cells. Hydrogen source technology has become one of the technical bottlenecks restricting the further commercial application of fuel cells.
[0003] At present, hydrocarbon compounds such as gasoline, diesel, natural gas and methanol are used as raw materials to produce hydrogen on site through reforming reaction, which has become a research hotspot at home and abroad. This hydrogen production method has the advantages of high energy density and high energy conversion rate. In addition, liquid fuel is easy to store and transport, and has advantages in economy and safety compared with hydrogen. A large amount of CO is inevitably generated in the process of hydrogen production by reforming of carbon hydrogen fuel. In order to further improve the content of H2 and eliminate the poisoning of platinum electrode in fuel cell, water vapor shift reaction needs to be carried out on the gas after reforming of carbon hydrogen fuel.
[0004] Most of the existing reactors use magnesium oxide as adsorbent to adsorb the entering raw materials, and then discharge after treatment. The adsorbent reduces in effectiveness after a period of use and needs to be regenerated after heat treatment. The existing reactor needs to take out the adsorbent box and replace the adsorbent in the box when recovering the adsorbent, which is a relatively cumbersome process and makes the reactor have a long downtime.

[0026] Reference Figures 1-4 A catalyst reactor includes a reactor body, a multi-station turntable, and an adsorbent chamber 9. The reactor body has a split structure, including an upper reactor 1 and a lower reactor 5 that are fixedly connected. A space adapted to the adsorbent chamber 9 is formed between the upper reactor 1 and the lower reactor 5. The multi-station turntable is provided with at least two sets of mounting holes 6, and the adsorbent chamber 9 is disposed in the mounting holes 6. A heating seat 13 is provided below the multi-station turntable, and the heating seat 13 is located on one side of the lower reactor 5.
[0027] During operation, material is fed into the inlet at the bottom of the reactor body. The material reacts from bottom to top, passing through the adsorbent chamber 9. The adsorbent adsorbs CO from the material, increasing the H2 content and eliminating CO poisoning of the platinum electrode in the fuel cell. After a period of use, the adsorbent's effectiveness decreases, requiring heat treatment for regeneration to restore its original performance. The position of the adsorbent chamber 9 can be changed using a multi-station turntable, and it is heated by the heating seat 13 to restore its original function. After restoration, the multi-station turntable is rotated again to replace the adsorbent chamber 9 in the reactor body, and the replaced adsorbent chamber 9 is then regenerated by heating. The heating seat 13 includes an upper heating tube and a lower guide fan, with the guide fan blowing the heat generated by the heating tube into the adsorbent chamber 9.
[0028] The upper reactor 1 and / or the lower reactor 5 are provided with multiple catalyst layers, including a Ni-based catalyst layer (such as one or more combinations of alumina-supported Ni catalyst, Ni-Fe composite oxide catalyst, cerium oxide-supported Ni catalyst, and zirconium oxide-supported Ni catalyst); an Fe-based catalyst layer (such as one or more combinations of Fe-Cr composite oxide catalyst, Fe-Ce-Al composite oxide catalyst, Fe-Ce-Zr composite oxide catalyst, and Fe-Zr-Al composite oxide catalyst); and a Cu-based catalyst layer (such as one or more combinations of Cu-Zn-Al composite oxide catalyst, noble metal-doped Cu / Al2O3 catalyst, and Ce and Zr-doped Cu / Al2O3 catalyst).
[0029] In other preferred embodiments, the adsorbent chamber 9 has a cylindrical structure with permeable grids on both the upper and lower ends, and is filled with magnesium oxide-based particles.
[0030] In other preferred embodiments, the mounting hole 6 is an elongated hole, the adsorbent chamber 9 has a circular cross-section, and sliders 8 are fixedly connected to the outer walls on both sides of the adsorbent chamber 9. A limit rod is fixedly connected to the multi-station turntable, and the sliders 8 are slidably connected to the limit rod. A return spring rod 7 is provided on the side of the mounting hole 6 near the center of the multi-station turntable. One end of the return spring rod 7 is fixedly connected to the fixed base, and the other end abuts against the outer wall of the adsorbent chamber 9. A vibration frame is provided on the outside of the multi-station turntable, and the vibration frame is located on one side of the heating base 13. The return spring rod 7 can keep the adsorbent chamber 9 at the reaction station abutting against the edge of the mounting hole 6 to adapt to the operation of the reactor body. When the adsorbent chamber 9 moves to the heating station, the adsorbent particles in the adsorbent chamber 9 can be shaken by the action of the first vibration block and the return spring rod 7, so that the adsorbent particles inside are heated evenly.
[0031] Specifically, the vibration frame has a built-in first vibration motor, and the output end of the first vibration motor is equipped with a first vibration block, which abuts against the outer wall of the adsorbent chamber 9.
[0032] Specifically, three sets of mounting holes 6 are provided, with an included angle of 120°, corresponding to the reaction station, spraying station, and heating station on the multi-station turntable. The spraying station includes a liquid storage hopper 12, a liquid guide frame, and a spray head 10. The liquid storage hopper 12 is located below the spraying station, and the spray head 10 is located above the spraying station. The liquid storage hopper 12 and the spray head 10 are connected by the liquid guide frame. Through the set spraying station, the effective ingredients can be sprayed onto the surface of the adsorbent particles, and replenishment can be carried out in a timely manner when loss occurs (when loss decreases, spraying can be performed again after the multi-station turntable rotates multiple times).
[0033] The liquid storage tank 12 has a built-in filter plate. The top of the filter plate forms a liquid receiving cavity for receiving the liquid dripping from the adsorbent chamber 9. The bottom of the filter plate forms a liquid storage cavity, and a pump body is installed in the liquid storage cavity. The pump body is connected to the spray head 10 through the liquid outlet pipe 11.
[0034] The liquid guide frame incorporates a second vibration motor, and the output end of the second vibration motor is equipped with a second vibration block, which abuts against the outer wall of the adsorbent chamber 9. This structure utilizes the action of the second vibration block and the return spring rod 7 to cause the adsorbent particles within the adsorbent chamber 9 to vibrate, ensuring uniform spraying of the adsorbent particles.
[0035] In other preferred embodiments, the multi-station turntable includes a base, a drive motor 4, and an indexing plate. The drive motor 4 is fixedly connected to the base, and the indexing plate is driven by the drive motor.
[0036] In other preferred embodiments, a first lifting frame is provided on the outer wall of the upper reactor 1, and an upper sealing pipe 2 is provided at the free end of the first lifting frame. A second lifting frame is provided on the outer wall of the lower reactor 5, and a lower sealing pipe 3 is provided at the free end of the second lifting frame. The outer diameters of the upper reactor, the lower reactor, and the adsorbent chamber are the same. The inner diameter of the upper sealing pipe 2 is the same as the outer diameter of the upper reactor 1, and the inner diameter of the lower sealing pipe 3 is the same as the outer diameter of the lower reactor 5. This structure enhances the sealing effect between the reactor body and the adsorbent chamber 9, preventing gas leakage during the reaction process.
[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
