CATALYST CONTAINING RUTHENIUM AND ZINC OXIDE FOR CO OXIDATION |
摘要 |
Provided is a ruthenium-based catalyst having from about 1 to 10 wt. % of a ruthenium component and at least about 0.5 wt. % of zinc oxide. In one embodiment of the catalyst, zinc oxide itself serves as a support on which the ruthenium is dispersed. In another embodiment, the ruthenium component and the zinc oxide are dispersed on a refractory oxide support other than zinc oxide. In a process aspect, the ruthenium-based catalyst can serve as a preferential oxidation catalyst in processes for removing carbon monoxide from an input gas stream containing carbon monoxide, hydrogen and oxygen. The invention also provides articles wherein multi-stage preferential oxidation processes for removal of carbon monoxide from hydrogen streams can be conducted. |
