Abstract
A high temperature shift process using an iron oxide-containing catalyst wherein the feed gas is contacted with an iron-free, copper-containing, catalyst at an inlet temperature in the range 280-370° C. before contact with the iron oxide-containing catalyst in order to effect some shift reaction and thus avoid conditions conducive to over-reduction of the iron oxide containing catalyst.
