Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, and in particular to a catalyst reactor. Background Art

[0002] A fuel cell is an energy conversion device that can continuously convert chemical energy into electrical energy. It has the advantages of being clean and efficient, and is of great significance to improving the environment and achieving sustainable development of energy. At present, the hydrogen sources required for fuel cells are mostly obtained by hydrogen production from fossil fuels, hydrogen extraction from chemical byproducts, hydrogen production from biomethanol and methane, and hydrogen production from natural energy such as solar energy and wind energy. However, the storage and transportation of external hydrogen has problems such as high cost and great safety hazards, which restrict the supply of hydrogen sources for fuel cells. Hydrogen source technology has become one of the technical bottlenecks restricting the further commercial application of fuel cells.

[0003] At present, on-site hydrogen production technology using gasoline, diesel, natural gas, methanol and other hydrocarbons as raw materials through reforming reaction has become a hot topic of research at home and abroad. This method of hydrogen production has the advantages of high energy density and high energy conversion rate. In addition, liquid fuels are easy to store and transport, and have advantages over hydrogen in terms of economy and safety. A large amount of CO is inevitably generated during the process of reforming hydrocarbon fuels to produce hydrogen. In order to further increase the H2 content and eliminate the poisoning of CO to the platinum electrode in the fuel cell, it is necessary to perform a water vapor shift reaction on the gas after the reforming of hydrocarbon fuels.

[0004] Most existing reactors use magnesium oxide as an adsorbent to adsorb incoming raw materials, which are then discharged after treatment. After a period of action, the adsorbent's effectiveness decreases and requires heat treatment before regeneration. When restoring the adsorbent in the existing reactor, the adsorbent box needs to be taken out and then the adsorbent in the box needs to be replaced. This step is relatively cumbersome and causes a long reactor downtime. Summary of the invention

[0026] Reference Figure 1-Figure 4 A catalyst reactor comprises a reactor body, a multi-station turntable and an adsorbent bin 9. The reactor body is a split structure, comprising an upper reactor 1 and a lower reactor 5 that are fixedly connected. A space adapted to the adsorbent bin 9 is formed between the upper reactor 1 and the lower reactor 5. At least two groups of mounting holes 6 are arranged on the multi-station turntable, and the adsorbent bin 9 is arranged in the mounting holes 6. A heating seat 13 is arranged under the multi-station turntable, and the heating seat 13 is located on one side of the lower reactor 5.

[0027] When in use, the material is poured into the feed port at the bottom of the reactor body, and the material reacts from bottom to top. After passing through the adsorbent bin 9, the adsorbent adsorbs CO in the material, increases the H2 content, and eliminates the poisoning of CO to the platinum electrode in the fuel cell. After a period of action, the adsorbent has a reduced effect, and needs to be heat-treated before it can be regenerated to restore its original effect. The position of the adsorbent bin 9 can be changed by the multi-station turntable, and it can be heated by the heating seat 13 to restore its original function. After recovery, the multi-station turntable is rotated again to replace the adsorbent bin 9 in the reactor body, and the replaced adsorbent bin 9 is heated and regenerated. The heating seat 13 includes an upper heating tube and a lower ventilator, and the ventilator blows the heat generated by the heating tube into the adsorbent bin 9.

[0028] A multi-stage catalyst layer is arranged in the upper reactor 1 and / or the lower reactor 5, including a Ni-based catalyst layer (such as one or several combinations of Ni catalysts loaded on aluminum oxide, Ni-Fe composite oxide catalysts, Ni catalysts loaded on cerium oxide, and Ni catalysts loaded on zirconium oxide); a Fe-based catalyst layer (such as one or several combinations of Fe-Cr composite oxide catalysts, Fe-Ce-Al composite oxide catalysts, Fe-Ce-Zr composite oxide catalysts, and Fe-Zr-Al composite oxide catalysts); and a Cu-based catalyst layer (such as one or several combinations of Cu-Zn-Al composite oxide catalysts, precious metal-doped Cu / Al2O3 catalysts, and Ce, Zr-doped Cu / Al2O3 catalysts).

Through the provided spraying station, the effective ingredients can be sprayed on the surface of the adsorbent particles, and replenished in time when loss occurs (when the loss is reduced, spraying and replenishment can be performed after the multi-station turntable rotates multiple times).

[0033] Among them, the liquid storage hopper 12 has a built-in filter plate, and a liquid receiving cavity is formed on the top of the filter plate for receiving liquid dripping from the adsorbent bin 9.

[0035] In other preferred embodiments, the multi-station turntable includes a base, a drive motor 4 and a dividing plate. The drive motor 4 is fixedly connected to the base, and the dividing plate is driven by the drive motor.
