Abstract

The invention discloses a super-infrared air flotation shallow fluidized reactor. The reactor with a structure described in the invention is a novel fluidized reactor for ZIF pyrolysis. The super-infrared air flotation shallow fluidized reactor comprises a main gas inlet pipe, a lower gas inlet pipe of a porcelain boat, a tubular furnace, a collection target, an upper cover of the porcelain boat, a gas exchange hole, a porcelain boat main body, a silk screen, a magnetic ball, a lower gas inlet of the porcelain boat, a gas outlet pipe, a super-infrared control device and a super-infrared pulse transmitting device, According to the invention, on the basis of a traditional tube furnace reactor, a shallow fluidization technology and a super infrared magnetic suspension technology are applied to solve the problem that ferromagnetic ZIF materials are heated unevenly due to agglomeration in a pyrolysis process; the porcelain boat is improved and gas exchange holes are introduced to solve the problem that powder is easily blown away by shielding gas; meanwhile, a collection target is added, so zinc volatilized in a ZIF-8 pyrolysis process can be collected. The reactor is simple in structure, and various problems in the pyrolysis process can be solved.

Description

technical field [0001] The invention relates to the field of fluidized reactors, in particular to an ultra-infrared air flotation shallow layer fluidized reactor. Background technique [0002] The metal M-N-C material formed by pyrolysis of zeolite imidazole-based framework ZIF has attracted extensive attention in the field of heterogeneous catalysis because of its special shape, simple preparation process, relatively low price and efficient catalysis of various chemical reactions. ZIF-8, which is formed by the coordination of zinc ions and 2-methylimidazole, can prepare a variety of M-N-C catalysts due to the volatilization of Zn during the pyrolysis process to move other metal ions to the N-C site, so ZIF-8 has wider application. [0003] In the field of electrocatalysis, M-N-C catalysts with different atomic sites can catalyze a variety of reactions, such as: oxygen reduction reaction ORR, oxygen evolution reaction OER, hydrogen evolution reaction HER and carbon dioxide ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the ferromagnetic ZIF material is affected by uneven heating due to powder agglomeration during heat treatment, the problem that the product powder is easily blown away by the protective gas due to the unsealed upper cover of the porcelain boat, and the high temperature volatilization of ZIF-8 The zinc condenses at the cold end and causes the blockage of the gas path, so a new type of ultra-infrared air flotation shallow fluidized reactor is provided

By passing the protective gas from bottom to top in the vertical direction of the porcelain boat, the powder is suspended to form a shallow fluidized state, thereby solving the problem of local uneven heating and continuously updating the powder surface
