Copper catalysts for the steam reforming of methanol. Analysis of the Preparation Variables

Methanol reforming takes place in the presence of copper supported on α-alumina, at atmospheric pressure and temperatures in the range of 280-300°C. In this work the effect of preparation variables, such as impregnation methods and calcination temperature, on the catalyst activity, selectivity and s...
