Cr-free catalysts for water gas shift reaction having high activities for CO removal

摘要

The present invention is a non-chromium-based relates to a high temperature water gas shift reaction catalyst, specifically a fuel through a modification in order to remove the carbon monoxide generated in the step of obtaining the hydrogen to form a solid solution of iron and nickel oxide, and a two-component not containing chromium compound catalyst or the iron, nickel and zinc, or with a transition metal further comprises a cobalt WGS characterized in that the three-component composite catalyst relates to a catalyst for the reaction. ; According to the present invention, the catalyst of hexavalent toxic chromium is compared with the conventional catalyst comprising chromium does not produce, practical and economical efficiency is also excellent catalysts do not contain a noble metal. In addition, by showing higher activity than the conventional high-temperature water gas shift reaction catalyst, used as a new catalyst that can replace the conventional catalysts are expected.
