环己烯水合法是制备己内酰胺的主流工艺路线，其中环己烯通常由苯加氢生成，苯中微量的硫可能会导致苯加氢钌催化剂中毒，影响催化剂寿命。提出了一种新的苯预处理脱硫催化剂装填方案，对比了钌脱硫催化剂和钯脱硫催化剂的运行数据，介绍了钌脱硫催化剂的再生方案，总结和展望了目前钌脱硫催化剂的研究现状和发展方向。

Cyclohexene hydration is the mainstream process for the preparation of caprolactam,in which cyclohexene is made by hydrogenation of benzene.Trace sulfur in benzene may lead to poisoning of ruthenium catalyst for hydrogenation of benzene and affect the catalyst lifespan.A new packing scheme for benzene pretreatment desulfurization catalyst is proposed.The operating data of ruthenium desulfurization catalyst and palladium desulfurization catalyst are compared,and the regeneration scheme for ruthenium desulfurization catalyst is introduced.Current research status and development direction of ruthenium desulfurization catalyst are summarized and prospected.
