Bismuth molybdate-based catalysts, method of preparing thereof and method of preparing 1,3-butadiene using thereof
This invention relates to a bismuth molybdate catalyst, a preparation method thereof, and a method of preparing 1,3-butadiene using the same, and to a bismuth molybdate catalyst, a preparation method thereof, and a method of preparing 1,3-butadiene using the same, in which 1,3-butadiene can be prepared through oxidative dehydrogenation directly using a C4 mixture including n-butene and n-butane as a reactant in the presence of a mixed-phase bismuth molybdate catalyst including α-bismuth molybdate (Bi2Mo3On) and γ-bismuth molybdate (Bi2MoO6). According to this invention, the C4 raffinate, containing many impurities, is used as a reactant, without an additional n-butane separation process, thus obtaining 1,3-butadiene at high yield. Unlike complicated multicomponent-based metal oxides, the catalyst of the invention has simple constituents and synthesis routes, and can be easily formed through physical mixing, and thus is very advantageous in assuring reproducibility and can be directly applied to commercial processes.
