CATALYST FOR PRODUCTION OF BUTADIENE, PROCESS FOR PRODUCING THE CATALYST, AND PROCESS FOR PRODUCING BUTADIENE USING THE CATALYST

摘要

A catalyst for producing butadiene using n-butene as a raw material, a process for producing the same and a process for producing butadiene using the catalyst. Specifically, a catalyst for producing butadiene by gas-phase contact oxidative dehydrogenation of n-butene, which is capable of stably producing butadiene in a high yield from the beginning of the reaction, a process for producing the same and a process for producing butadiene. The catalyst is a shaped catalyst containing a complex metal oxide having molybdenum as an essential ingredient, wherein the pore volume of macropores is 80% or more, more preferably 90% or more, based on the total pore volume.
