摘要： The present invention relates to a process for preparing a co-precipitated Cr2O3/Al2O3 catalyst promoted by Zinc, said process comprising co-precipatation of chromium and aluminum metal hydroxides from corresponding trivalent metal salt solutions using NH4OH, NaOH or KOH as a base and followed by calcination to give mixed oxide precatalyst in amorphous from which is impregnated with an activity promoting amount of Zinc compound. The catalyst is used for the preparation of HFC-134a by fluorination of trichloroethylene and fluorination of intermediate of the former reaction (HCFC-133a).
