Abstract
The present invention relates to a ferrite-based catalyst composite, a method of preparing the same, and a method of preparing butadiene using the same. More particularly, the present invention provides a ferrite-based catalyst composite having a shape that allows effective dispersion of excess heat generated in a butadiene production process and prevention of catalyst damage and side reaction occurrence by reducing direct exposure of a catalyst to heat, a method of preparing the ferrite-based catalyst composite, and a method of preparing butadiene capable of lowering the temperature of a hot spot and reducing generation of Cox by allowing active sites of a catalyst to have a broad temperature gradient (profile) during oxidative dehydrogenation using the ferrite-based catalyst composite, and thus, providing improved process efficiency.
