Abstract

The invention discloses an ultra-infrared air-floating shallow-layer fluidized reactor, which is a novel fluidized reactor for ZIF pyrolysis. Including the main air intake pipe, the air intake pipe under the porcelain boat, the tube furnace, the collection target, the upper cover of the porcelain boat, the gas exchange hole, the main body of the porcelain boat, the wire mesh, the magnetic ball, the air inlet under the porcelain boat, the air outlet pipe, and the ultra-infrared control device and ultra-infrared pulse emission device; the invention is based on the traditional tube furnace reactor, and designs a method of applying shallow fluidization technology and ultra-infrared magnetic levitation technology to solve the problem of uneven heating caused by agglomeration of ferromagnetic ZIF materials during the pyrolysis process To solve the problem, improve the porcelain boat and introduce gas exchange holes to solve the problem that the powder is easily blown away by the protective gas. At the same time, adding a collection target can collect the zinc volatilized during the pyrolysis of ZIF‑8. The device has a simple structure and can solve various problems in the pyrolysis process.

Description

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

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
