Photocuring 3D printing manufacturing method of integral SiC-based microreactor

Abstract

The invention discloses a photocuring type 3D printing manufacturing method of an integral type SiC-based microreactor. The preparation method comprises the following steps: firstly, carrying out curing molding on a reactor by adopting integrated photocuring 3D printing, carrying out high-temperature treatment, and loading methanol reforming slurry and methanol combustion slurry by adopting a flow impregnation process, so as to obtain the SiC microreactor with self-heating starting performance; structurally, inlets and outlets of reformed gas and combustion gas are respectively located at the top and the bottom of the reactor main body, combustion chambers and reforming chambers in the reactor main body are alternately arranged, and power amplification can be realized through superposition of different layers. High-precision and short-period microreactor manufacturing can be realized, the problem of poor air tightness of the microreactor is solved, the microreactor has the characteristics of high catalyst loading strength, high temperature resistance, oxidation resistance, corrosion resistance and long service lifetime, meanwhile, no contact thermal resistance exists between a high-porosity carrier and the wall surface of the reaction chamber, the heat transfer performance is enhanced, and the hydrogen production performance is effectively improved.

Description

technical field [0001] The invention relates to a methanol reforming hydrogen production reactor and a printing manufacturing method thereof in the field of manufacturing a reforming hydrogen production reactor, in particular to a manufacturing process and structural design of a methanol reforming hydrogen production reactor. Background technique [0002] The "China Hydrogen Energy and Fuel Cell Industry White Paper 2020" issued by the China Hydrogen Energy Alliance indicates that under the scenario of my country's carbon neutrality in 2060, hydrogen energy will account for about 20% of my country's final energy consumption. At present, there are high compression energy consumption and leakage risks in the process of directly storing / transporting hydrogen in hydrogen storage tanks. The methanol mobile hydrogen production technology uses methanol as the fuel for hydrogen production. Methanol in a liquid state at room temperature is easy to transport, has a wide range of sourc...
