Supported copper-based catalyst and application thereof

The invention provides a supported copper-based catalyst. The supported copper-based catalyst is prepared through a specific coprecipitation process. The invention also provides application of the supported copper-based catalyst and a method for hydrogen production by methanol steam reforming. The catalyst provided by the invention takes CuO and ZnO as active catalytic components and Al2O3 and MgAl2O4 spinel as a composite carrier, has an excellent catalytic effect, can resist water and heat, has good stability, and is very suitable for being used as a catalyst for hydrogen production by methanol steam reforming. According to the method for hydrogen production through methanol steam reforming, due to the fact that the catalyst is used, the reaction efficiency is obviously improved, the selectivity of a by-product CO is remarkably reduced, and the generation amount of carbonaceous organic matter impurities is reduced. 本发明提供了一种负载型铜基催化剂，通过特定的共沉淀工艺制备得到。本发明还提供了所述负载型铜基催化剂的用途以及一种甲醇水蒸汽重整制氢的方法。本发明所述的催化剂以CuO和ZnO作为活性催化成
