Ni-S-Y hierarchical pore molecular sieve catalyst, preparation method thereof and application of Ni-S-Y hierarchical pore molecular sieve catalyst in synthesis of tert-dodecyl mercaptan

The invention provides a Ni-S-Y hierarchical pore molecular sieve catalyst, a preparation method thereof and application of the Ni-S-Y hierarchical pore molecular sieve catalyst in synthesis of tert-dodecyl mercaptan, and belongs to the technical field of green chemical catalysis and new material preparation. According to the Ni-S-Y hierarchical pore molecular sieve catalyst, tetraethoxysilane, tetrapropylammonium hydroxide, aluminum isopropoxide and distilled water serve as raw materials and react with organosilane, a hierarchical pore Y molecular sieve carrier is obtained, then dielectric barrier discharge plasma modification is conducted, and the Ni-S-Y hierarchical pore molecular sieve catalyst is obtained. And introducing Ni into the plasma modified Y molecular sieve carrier by adopting an over-volume impregnation method, and further vulcanizing to obtain the Ni-S-Y hierarchical pore molecular sieve catalyst. The prepared catalyst can be used for catalyzing triisobutylene to synthesize tert-dodecyl merca
