Novel methanol reformer

Abstract

The invention discloses a novel methanol reformer, and relates to the field of industrial equipment, and the methanol reformer comprises an alcohol water input port, a hydrogen-rich gas output port, a methanol air inlet, a reaction tail gas outlet, a cavity, a heat transfer plate and a catalyst layer. The cavity comprises three layers of runners, namely an upper-layer preheating treatment runner, a middle-layer methanol catalytic combustion runner and a lower-layer methanol catalytic reforming runner; the preheating treatment flow channel is used for receiving a methanol water solution conveyed through the methanol water input port and preheating the methanol water solution to generate methanol water vapor; the methanol catalytic combustion flow channel is used for providing heat for the preheating treatment flow channel and the methanol catalytic reforming flow channel; the methanol catalytic reforming flow channel is used for reforming methanol steam to produce hydrogen; each flow channel is of a snakelike flow channel structure, and the longitudinal direction of each flow channel is of a symmetrical increasing wave function. The problem of low utilization rate of the existing methanol reformer catalyst can be effectively solved, and the methanol steam reforming efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of industrial equipment, in particular to a novel methanol reformer. Background technique [0002] Energy is undoubtedly a major topic of common concern in the world today. Due to the continuous growth of global energy consumption and the climate problems caused by energy consumption, more and more people of insight believe that fuel cell stacks, as a real The "zero emission, pollution-free" clean energy has attracted the attention of countries all over the world. However, hydrogen fuel cells are subject to high hydrogen refueling station construction costs and hydrogen storage and transportation costs. Not only in China, but also in global promotion. Compared with the pure hydrogen route, methanol reforming fuel cell vehicles do not require high-pressure hydrogen storage tanks, nor do they need to build hydrogen refueling stations, so the promotion cost is low. Also compared with the methanol engine, the e...
