Abstract

A method is described for producing a high temperature shift catalyst, not requiring a reduction step prior to use, by precipitating a composition containing divalent and trivalent iron compounds and a modifier metal selected from trivalent chromium and/or manganese compounds from an aqueous solution containing iron and modifier metal salts with a base, and forming the resultant precipitate into shaped catalyst units, without exposing said precipitate to an oxidizing atmosphere at temperatures above 200° C.
