Study Advances in Ruthenium Catalysts for Hydrogenation of Benzene to Cyclohexene

钌系催化剂是苯加氢制备环己烯反应中最有效的催化剂。文章综述了国内外苯选择加氢制环己烯催化剂的发展历程,重点介绍了活性组分、载体、助剂、制备方法及添加剂对钌催化剂活性及选择性的影响,分析了其影响原因,并指出了提高钌系催化剂效率的关键因素,为高效能的催化剂探索指明了发展方向。

The ruthenium catalyst was the most effective catalyst in selective hydrogenation of benzene to cyclohexene. Development of catalysts for selective hydrogenation of benzene to cyclohexene was reviewed in this paper. Influential factors for selective hydrogenation of benzene to cyclohexene over ruthenium catalysts were specifically introduced and analyzed, included active ingredients, carriers, additives, preparation methods and additives. The key factors to improve efficiency of the catalyst and the development direction for exploring efficient catalyst were also pointed out.
