Alpha-methylstyrene hydrogenation catalyst and preparation method and application thereof

The invention provides a nickel-based catalyst and a preparation method and application thereof, a carrier of the nickel-based catalyst is silicon dioxide, and on the basis of the mass of the carrier, the silicon dioxide is loaded with not more than 10 wt% of nickel. According to the technical scheme provided by the invention, the provided novel nickel-based catalyst is used for preparing isopropyl benzene through hydrogenation of alpha-methylstyrene, the industrial index requirement is met, and the preparation cost and the production cost of the catalyst are greatly reduced by avoiding the use of palladium noble metal. 本发明提供一种镍基催化剂及其制备方法和用途，所述镍基催化剂的载体为二氧化硅，以所述载体的质量为基准计，所述二氧化硅上负载有不超过10wt％的镍。本申请中提供的技术方案中，提供的新的镍基催化剂，其用于α-甲基苯乙烯加氢制异丙苯，既满足了工业化的指标要求，又通过避免使用钯贵金属，极大降低了催化剂制作成本和生产成本。
