| 摘要 |
The invention relates to the use of a catalytic composition for selective methanization of carbon monoxide in hydrogen- and carbon dioxide-containing streams, wherein the active component used is ruthenium and the support material is a lanthanum-cerium-zirconium oxide, where the total loading of the support material with the active component is 0.1 to 20% by weight, based on the total weight of the catalytically active composition, and the support material comprises a lanthanum oxide content of 0.1 to 15% by weight, a cerium oxide content of 0.1 to 15% by weight and a zirconium oxide content of 30 to 99.8% by weight, based on the weight of the overall support material. |
