CR-FREE CATALYSTS FOR WATER GAS SHIFT REACTION HAVING HIGH ACTIVITIES FOR CO REMOVAL

摘要

The present invention be one be not based on chromium be related to a kind of high-temperature water gas shift reaction catalyst, particularly pass through a kind of fuel of modification, in order to remove carbon monoxide, it is generated in the step of obtaining a solid solution of the hydrogen to form iron and nickel oxide, one binary does not include chromium compound catalyst or iron, nickel and zinc, it or with a transition metal further include a cobalt WGS, it is characterised in that three-component composite catalyst is related to a kind of catalyst for reaction. ;According to the present invention, the catalyst of the toxic chromium of six ranks is compared the conventional catalyst including chromium and is not produced, and actual and economic effect is also that excellent catalysts do not include a noble metal. In addition, being expected by showing higher activity than conventional high-temperature water gas shift reaction catalyst as the new catalyst that can replace conventional catalyst.
