Abstract

The invention discloses a self-heating laminated micro-channel reforming hydrogen production reactor, which comprises an upper cover board, an endothermic reaction substrate, an exothermic reaction substrate and a lower cover board, wherein the upper cover board is formed with a vapour reforming reactant inlet, a vapour reforming product outlet, an inlet of hydrocarbon in partial oxidation reforming reaction, and an inlet of oxygen in partial oxidation reforming reaction; the endothermic reaction substrate comprises a vaporization cavity, a vapour reforming reaction cavity, a vapour guide channel and hot circulation channels located on two sides of the endothermic reaction substrate; the exothermic reaction substrate comprises a catalytic combustion cavity, and a partial oxidation reforming reaction cavity, wherein the catalytic combustion cavity is connected with the partial oxidation reforming reaction cavity one another through a channel formed on the middle part of the exothermic reaction substrate. The reactor provided by the invention is characterized by that the whole micro-reactor can be started up and operated with self-heat without an external heat source, and the reactor can greatly improve the efficiency of methanol-vapour reforming hydrogen production reaction; the reactor provided by the invention further realizes recycling waste heat obtained by burning the reaction products and reduces loss of heat energy.

Description

technical field [0001] The invention relates to a methanol reforming hydrogen production reactor, in particular to a self-heating type laminated microchannel reforming hydrogen production reactor. Background technique [0002] The increasing energy crisis and environmental pollution force people to look for new environmentally friendly energy sources. Hydrogen energy has attracted widespread attention because of its high combustion calorific value, clean and environmental protection. However, direct hydrogen supply / storage has disadvantages such as low storage energy density, high risk, large volume, energy consumption, and huge investment. Therefore, the on-site production of hydrogen through related chemical reactions is the development direction to solve the above problems. [0003] Hydrogen production by reforming hydrocarbon fuels is a commonly used hydrogen production method at home and abroad; especially alcohols such as methanol and ethanol can be obtained from rene...
