Abstract

The invention provides a novel methanol reformer comprising a guiding mixing plate and catalyst coatings. The guiding mixing plate is a honeycomb structure. The inner and outer sidewalls of the guiding mixing plate are provided with the catalyst coatings. The novel methanol reformer provided by the invention, by means of the catalyst coatings on the inner sidewall and the outer sidewall of the guiding mixing plate, enables a fluid to flow through honeycomb holes in the guiding mixing plate. Thus, the fluid can be sufficiently mixed and can be in well contact with the catalyst coatings, therebycompletely decomposing methanol, increasing hydrogen production, improving reforming efficiency and heat exchange efficiency, and make the reformer compact, efficient and good in vibration resistance.

Description

technical field [0001] The invention relates to the technical field of methanol water hydrogen production 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 th...
