Cu-Zr catalyst for steam reforming of methanol to prepare hydrogen and its prepn

Abstract

The present invention discloses one kind of Cu-Zr catalyst for steam reforming of methanol to prepare hydrogen and its preparation process. The catalyst without Zn and Al components contains CuO10-80 mol%, ZrO2 20-90 mol% and MOx 0-20 mol%, where M is one of Ce, La, Fe, Y and Mn. The Cu-Zr catalyst is used for steam reforming of methanol to prepare hydrogen, and has high activity, high hydrogen selectivity and very high stability. Specifically, it has conversion rate in steam reforming of methanol of 90-99 %, hydrogen selectivity of 95-99 % and CO content in the product lower than 0.5 %.

Description

technical field

[0001] The invention relates to methanol steam reforming hydrogen production technology, and in particular provides a zinc-aluminum component-free copper-zirconium-based multi-component methanol steam reforming hydrogen production catalyst and a preparation method thereof. technical background

[0002] Hydrogen is one of the ideal clean energy sources. The biggest obstacle to its utilization lies in the difficulty of storage and distribution. Methanol is considered to be the most promising high-energy-carrying fuel. It has the advantages of cheap and easy to obtain, high energy density, low carbon content, and convenient transportation and storage. It can be used to generate hydrogen instantly through catalytic conversion, which can effectively solve the problem of hydrogen energy. There are various problems in utilization (J. Power Source, 2002, 106, 249). Catalytic hydrogen production from methanol has good application prospects, such as directly supplying...
