| 简介 |
The present invention relates to the field of sulfur-tolerant catalysts, and discloses a catalyst and a preparation method therefor, and a method for a sulfur-tolerant shift catalytic reaction. The catalyst contains a support and a molybdenum oxide, a cobalt oxide and a cobalt-molybdenum-based perovskite composite oxide supported on the support, wherein the cobalt-molybdenum-based perovskite composite oxide contains the elements molybdenum, cobalt, an A element, and oxygen, wherein the A element is one or more of a rare earth metal element, an alkali metal element, and an alkaline earth metal element. The catalyst of the present invention also has a high sulfur-tolerant catalytic activity for raw material gases with a low H2S content. |
