ABSTRACT:
The life of copper-containing catalysts in the low temperature shift reaction of carbon monoxide with steam is limited as a result of slow poisoning by halogen and/or sulphur compounds. It has been found that the poisoning reaction and the shift reaction occur almost entirely on the surface of the catalyst pellets, and that the rate at which a catalyst charge loses activity can be decreased by having the catalyst in an inlet zone in a form more accessible to the reacting gas than that catalyst downstream thereof. The inlet zone catalyst pieces can be smaller and/or formed with indentations or protrusions and/or more macroporous in order to provide better access.
