Abstract

The invention relates to the field of methanol water steam hydrogen production by reforming, and discloses a micro-channel reactor. The micro-channel reactor comprises a reactor body, a U-shaped heat-insulation layer and a bottom plate, wherein a unit comprising a feeding channel, an evaporation cavity, a reforming cavity, a gas outlet channel and a microwave generation cavity is formed in the cavity of the reactor body; the tail end of the feeding channel successively communicates with the evaporation cavity and the reforming cavity; the gas outlet channel is formed in the top of the reforming cavity; a microwave generator is arranged in the microwave generation cavity, and is arranged on the lower portion of the reactor body; the U-shaped heat-insulation layer is arranged on the outsideof the reactor body to wrap the top surface and the two side surfaces of the reactor body; and the bottom plate is arranged on the bottom of the reactor body, and is connected with the U-shaped heat-insulation layer. The micro-channel reactor has the advantages of high energy utilization rate, low manufacturing cost and uniform heating.

Description

technical field [0001] The invention relates to the field of hydrogen production by steam reforming of methanol, in particular to a microchannel reactor. Background technique [0002] Microreactors have been widely used in various chemical processes due to their small size, large specific surface area, and excellent heat and mass transfer effects. [0003] At present, liquid alcohol hydrocarbons are used as fuels, which can be converted into hydrogen-rich gas instantaneously through the catalytic reaction of microchannel reactors under certain working conditions, providing a new solution for the hydrogen source problem of electronic power devices such as fuel cells. train of thought. Therefore, the new microchannel reactor for hydrogen production has aroused extensive interest of researchers. [0004] In terms of heat transfer, because the thickness of the fluid in the microreactor is reduced and the specific surface area is increased, the reactants in the microchannel can...
