METHOD OF PREPARING MULTICOMPONENT BISMUTH MOLYBDATE CATALYSTS COMPRISING FOUR METAL COMPONENTS AND METHOD OF PREPARING 1,3-BUTADIENE USING SAID CATALYSTS

摘要

A method of preparing multicomponent bismuth molybdate catalysts composed of four metal components and a method of preparing 1,3-butadiene using the catalyst, and particularly, to multicomponent bismuth molybdate catalysts composed of a divalent cationic metal, a trivalent cationic metal, bismuth and molybdenum, a preparation method thereof, and a method of preparing 1,3-butadiene from a C4 mixture including n-butene and n-butane using oxidative dehydrogenation are described.
