PROMOTED BISMUTH CERIUM MOLYBDATE CATALYSTS AND USE THEREOF IN OXIDATION-TYPE REACTIONS

摘要

A bismuth cerium molybdate catalysts oxide complex catalyst contains a promoting amount of an alkali metal Tl, Sm, Ag, Cu, Cr, Sb, rare earth metal other than Ce and Sm, Te, Ti, Zr, Th or mixture thereof. Such catalyst provides high yields of acrylonitrile in the ammoxidation of propylene and give improved results in other oxidation-type reactions.
