摘　　要：综述了国内苯加氢制环己烷催化剂及其工艺的现状和发展趋势,介绍了工业上主要的三大催化化反应工艺体系即UOP固体镍系催化剂气相反应工艺、Bexane的负载型铂系催化剂气相反应工艺和IFP的均相络合催化剂液相反应工艺,重点介绍了各主要催化体系及具有潜在发展前景的Ru系催化剂的最新进展,指出了尽管国内中小规模环己烷厂家均采用镍系气相反应工艺,但从装置规模的大型化和对产品高纯度要求来看,铂系气相工艺和镍系均相络合工艺具有更好的前景。Current industrial catalysts and the related process for hydrogenating of benzene to cyclohexane are reviewed. The heterogeneous Ni catalyst and the related gas-phase technology, supported Pt catalyst and the related gasphase technology, homogeneous catalyst and the related liquid-phase technology are introduced. The recent progress of the promising supported Ru catalyst for liquid-phase is highlighted. Concerning the trend for potential larger scale of benzene hydrogenation plant and the requirement for higher purity of product, the dominant heterogeneous Ni catalyst and related process maybe graduallv renlaeed by the other two relatively advanced one.
