摘　　要：面向解决催化裂化轻循环油(LCO)出路和富余柴油产能高值化利用的重大需求,以破解LCO加氢转化过程中芳环的加氢、环烷环的开环、烷基侧链的裂化和聚合结焦等关键反应对催化剂活性中心需求不一致的矛盾为切入点,通过创制新型催化材料、优化金属体系并改善制备方法等措施,开发了定向强化开环反应的柴油加氢改质催化剂RIC-3和兼具高开环与高断侧链性能的柴油加氢裂化专用催化剂RHC-100,构建了提高催化剂活性中心有效性、定向性和高效性的活性中心精细调控关键技术平台,形成了以RIC-3和RHC-100为核心、靶向调控多环芳烃加氢开环与裂化反应活性与选择性的催化剂族,可将劣质LCO转化为清洁柴油组分或高辛烷值汽油调合组分,为多环芳烃高效加氢转化技术的开发与应用提供技术支撑。The high-value utilization of light cycle oil(LCO)and surplus diesel production capacity is of great significance for saving precious petroleum resources and improving the refining benefits.With developing new catalytic materials,optimizing metal systems and improving preparation methods,two special LCO hydro-conversion catalysts RIC-3 and RHC-100 were developed,which could convert LCO to clean diesel components and high octane gasoline,respectively.Focused on enhancing the suitability of the LCO hydro-conversion between catalyst properties and requirements of target reaction processes,such as hydrogenation of aromatic ring,ring opening of naphthenic ring,cracking of alkyl cyclic hydrocarbons and polymerization aromatics,the catalyst precision design platform was designed and constructed to improve the effectiveness,orientation and efficiency of catalyst,and the catalyst family with RIC-3 and RHC-100 as the core was formed to target the ring-opening and cracking reactions of PAHs.The results of commercial applications showed that the performance of LCO hydro-conversion,the selectivity of the target products,as well as the directional utilization of H 2 were improved.Furthermore,the construction of the catalyst precision design platform and catalyst family will provide reference for LCO hydro-conversion to produce BTX.
