Patent

CA 2342877

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.

La présente invention concerne un procédé de conversion à haute température qui fait intervenir un catalyseur renfermant un oxyde de fer. Selon ce procédé, le gaz d'alimentation est mis en contact avec un catalyseur sans fer, renfermant du cuivre, à une température d'entrée comprise entre 280 et 370 DEG C avant d'entrer en contact avec un catalyseur renfermant de l'oxyde de fer, le but étant de déclencher une certaine conversion et donc d'éviter des conditions qui favorisent une réduction excessive du catalyseur avec oxyde de fer.
