Provided is a catalyst for an oxidative dehydrogenation reaction that comprises: a porous support; a core portion supported on the porous support and containing a first zinc ferrite-based catalyst; and a shell portion supported on the core portion and containing a second zinc ferrite-based catalyst, in which the first zinc ferrite-based catalyst and the second zinc ferrite-based catalyst are different from each other.

Catalyst for oxidative dehydrogenation reaction, and method for producing same

The method for preparing a ferrite-based coating catalyst including mixing a support, a ferrite-based catalyst, a cellulose-based additive, and water, in which a content of the cellulose-based additive is 0.5 wt % or less based on a total weight of the ferrite-based catalyst.

Method for producing ferrite-based coating catalyst and method for producing butadiene by using same

The present specification provides a method for preparing 1,3-butadiene, the method comprising: (A) obtaining a first product comprising a light component, 1,3-butadiene, and a heavy component from a reactant comprising butene; (B) separating the heavy component from a second product comprising the 1,3-butadiene and the light component by condensing the heavy component after heat exchanging the first product; and (C) separating concentrated heavy component by reboiling the condensed heavy component.

Method for preparing 1,3-butadiene

The method for preparing a ferrite-based coating catalyst including mixing a support, a ferrite-based catalyst, and water in a coating machine which is a rotating body, in which a weight ratio of the water based on a total weight of the support is 0.15 to 0.3.
