摘要

Process for the preparation of a catalyst precursor containing copper, aluminium and zinc. …This precursor is made up by mixing two ternary precursors at different stages of their manufacture, these two ternary precursors differing from each other in their metal stoichiometry (atomic ratios of Cu, Zn and Al), in their crystallographic structure and in their elementary morphology. …The catalyst obtained from this precursor can be employed particularly for methanol synthesis. ……
