Abstract
A copper, zinc, aluminum and boron catalyst is used as a low temperature methanol synthesis catalyst. The proportions of the catalyst components, in terms of metal atoms, are 30-70% of copper, 15-50% of zinc, 1-16% of aluminum and 0.3-5.3% of boron. This catalyst is prepared by adding an alumina sol to the mixture of copper, zinc and boron compounds and firing the total mixture.
