Oxidative Dehydrogenation of a C4 Raffinate-2 towards 1,3-Butadiene in a Two-Zone Fluidized Bed
The oxidative dehydrogenation of a C4 raffinate-2 consisting of n-butane, 1-butene, and 2-butene was conducted in a two-zone fluidized bed reactor using a Mo-V-MgO catalyst. This study reports the influence of the operating conditions temperature, hydrocarbon inlet height, and oxygen/hydrocarbon molar ratio on the product distribution, in particular on the formation of 1,3-butadiene. Axial concentration profiles were measured to elucidate the reaction sequence in the fluidized bed.
