Abstract

The invention discloses a self-heating staggered-arrangement micro-boss array type alcohol reforming device. The self-heating staggered-arrangement micro-boss array type alcohol reforming device comprises a hydrogen purification component, a reforming hydrogen production plate and a catalytic combustion plate sequentially from top to bottom. A reforming hydrogen production cavity is arranged in the reforming hydrogen production plate and loaded with a hydrogen production catalyst which is used for alcohol reformation so as to produce hydrogen; a catalytic combustion cavity is arranged in the catalytic combustion plate and loaded with a combustion catalyst which is used for alcohol combustion and heat supply. Heat is supplied for the reforming hydrogen production through alcohol combustion, so that the natural operation of the alcohol reforming device can be realized. Staggered-arrangement micro-boss array structures are arranged in the reforming hydrogen production cavity and the catalytic combustion cavity, so that the specific area is large and the heat transfer and mass transfer efficiency is high. In addition, the alcohol reforming device comprises the hydrogen purification component, so that the fuel conversion efficiency of the reforming hydrogen production cavity can be improved, and hydrogen at an outlet can be directly used for a hydrogen fuel battery. The self-heating staggered-arrangement micro-boss array type alcohol reforming device is compact in structure, convenient for catalysts to load, easy for the whole structure to assemble, and capable of being used in intermediate and small flow alcohol reforming hydrogen production situations.

Description

technical field

[0001] The invention relates to a self-heating type alcohol reformer, in particular to a self-heating staggered micro-protrusion platform array type alcohol reformer. technical background

[0002] Hydrogen energy has the advantages of high fuel calorific value, clean and environmentally friendly, and has attracted widespread attention. Among them, hydrogen fuel cells have achieved rapid development in recent years due to their high efficiency and high power density. With the vigorous development of hydrogen fuel cells, the issue of hydrogen supply for fuel cells has become a research hotspot. In the way of fuel cell hydrogen supply, an effective way is to use high-energy-density liquid fuels, especially low-carbon alcohols (such as methanol) to generate hydrogen through on-site reforming of the hydrogen production reaction system.

[0003] At present, there are three main methods of hydrogen production from alcohol reforming: steam reforming, partial oxidat...
