| 摘要 |
The invention relates to a catalyst system for the removal of carbon monoxide from a hydrogen containing feed gas. The system includes a first catalyst optimised to selectively oxidize carbon monoxide in the feed gas at temperatures below 100° C. The system also includes a second catalyst, downstream from the first catalyst, optimised to selectively oxidize carbon monoxide in the feed gas at temperatures above 100° C., the second catalyst having a higher carbon monoxide conversion rate than the first catalyst at 100° C.
