Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for preparing a ferrite-based coated catalyst, the method comprising: mixing in a coating machine that is a rotating body: a support comprising one or more of alumina, silica, cordierite, titania, zirconia, silicon nitride, and silicon carbide, a ferrite-based catalyst of Formula 1: AFe 2 O 4 Formula 1 wherein A is Cu, Ra, Ba, Sr, Ca, Be, Zn, Co, or Ni, and water, wherein a ratio of the weight of the water to the weight of the support is 0.15 to 0.3. 2. The method of claim 1 , wherein a content of the ferrite-based catalyst in the ferrite-based coated catalyst is 10 wt % to 40 wt % based on a total weight of the ferrite-based coating catalyst. 3. The method of claim 1 , further comprising: drying the resulting mixture after the mixing of the support, the ferrite-based catalyst, and the water. 4. A method for preparing butadiene, the method comprising: preparing a ferrite-based coating catalyst prepared by the preparation method of claim 1 ; and preparing butadiene in a reactor containing the ferrite-based coating catalyst via an oxidative dehydrogenation reaction of butene.
