Vulcanization type gasoline hydrogenation upgrading catalyst and method for preparing same

The invention relates to a method for preparing a vulcanization type gasoline hydrogenation upgrading catalyst. Gasoline hydrogenation catalysts are treated by vulcanizing agents with multiple sulfur ions and organic nitride which is used as a passivator at the low temperatures, active components in the gasoline hydrogenation catalysts comprise a type or a plurality of types of Mo and W of VI B groups and Co and Ni of VIII B groups, and stabilizers comprise a type or a plurality of types of Zn and Cd of II B groups, Na and K of I A groups and rare earth metal La and Ce. The method has the advantages that cascade full vulcanization can be carried out on metal oxide or precursors of the metal oxide, and strong acidic sites in ZSM-5 molecular sieve composite carriers can be selectively passivated; the vulcanization type gasoline hydrogenation upgrading catalyst prepared by the aid of the method is short in on-stream time, high in hydrogenation and olefin reduction upgrading activity, selectivity, carbon deposition resistance and liquid yield and low in octane number loss, and accordingly the method and the vulcanization type gasoline hydrogenation upgrading catalyst are particularly applicable to producing clean gasoline components from inferiorly catalytically cracked gasoline by means of hydrogenation and olefin reduction upgrading at a low cost.
