The invention discloses a supported rare earth modified metal catalyst, comprising a rare earth element modified alumina carrier and an active component supported on the rare earth element modified alumina carrier, wherein the active component includes an alkali metal element and tungsten element; in the supported rare earth modified metal catalyst, the rare earth element is calculated as oxide, and the mass percentage content is 0.4-5%. After adding rare earth elements for modification, the supported rare earth modified metal catalyst has better catalytic performance when it is applied to the reaction of methanol and hydrogen sulfide to prepare methyl mercaptan, improves the selectivity and yield of methyl mercaptan, and The reaction temperature and the circulation amount of hydrogen sulfide are reduced. |
