摘要： The present invention provides a method of producing a mixed manganese ferrite catalyst, and a method of preparing 1,3 -butadiene using the mixed manganese ferrite catalyst. Specifically, the present invention provides a method of producing a mixed manganese ferrite catalyst through a coprecipitation method which is performed at a temperature of 10 ~ 40 °C, and to a method of preparing 1,3 -butadiene using the mixed manganese ferrite catalyst through an oxidative dehydrogenation reaction, in which a C4 mixture containing n-butene, n-butane and other impurities is directly used as reactants without performing additional n-butane separation process or n-butene extraction. The present invention is advantageous in that 1,3-butadiene can be prepared directly using a C4 mixture including n-butane at a high concentration as a reactant through an oxidative hydrogenation reaction without performing an additional n-butane separation process, and 1,3-butadiene, having high activity, can be also obtained in high yield for a long period of time.

摘要： This invention relates to 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. According to this invention, it is possible to prepare catalysts having high activity for the preparation process of 1,3-butadiene only using four metal components as shown through systematic investigation of types and ratios of metal components, unlike conventional multicomponent metal oxide catalysts having a complicated composition of metal components.
