选择加氢催化剂结构与性能的研究进展

A review of selective hydrogenation catalysts on active center and performance

选择加氢催化剂是石油化工领域一类重要的催化剂,广泛应用于各类乙烯装置中C2、C3、C4等组分以及裂解汽油中炔烃和二烯烃的脱除等领域.本文从制备与处理方法、助剂、载体、活性中心结构形态、反应机理、非Pd催化剂6个方面,对近5年来选择加氢催化剂,特别是炔烃和二烯烃选择加氢催化剂结构与性能的研究进行了评述.

Selective hydrogenation catalysts are one of the most important kinds of catalysts used in petrol chemical industry due to their extensive applications in the removal of alkynes and dienes in C2, C3, C4 olefin stream and pyrolysis gasoline. In this review, we focus on the active center properties and catalyst performance, summarize its progress on selective hydrogenation in the past 5 years from six areas： preparation and process methods, promoters, supports, active center structure, reaction mechanism, and non-palladium catalysts.
