摘　　要：精细化分离是石油化工生产的关键技术及研究热点之一,其中C2(C2H2/C2H4和C2H4/C2H6)的高效精细分离更是现代化工过程中高质量生产的难点和新挑战.传统的热驱动分离过程(如精馏分离和选择性催化加氢分离)存在能耗高、经济效益低的缺陷,而采用非热驱动分离过程(如吸附分离和膜分离)可大幅度节能降耗.在众多吸附分离材料中,金属有机骨架(MOF)材料拥有庞大的组分/结构单元库,其组成和孔结构的可控、可调特性为C2的精细化高效分离带来了新的机遇.以此为导向,整理并归纳了近年来MOF^(+)材料(MOF及其复合材料)的晶体和孔道参数,分析其在高效分离C2方面的科学研究成果,针对MOF^(+)材料的设计、可控制备、孔径调控机制等关键科学问题,提出了未来MOF^(+)材料的研究趋势.Fine separation of mixture is the primary importance technology and hot topic in the petrochemical industry.In particular,high-efficiency separation of C2(C2H2/C2H4 and C2H4/C2H6)is a difficult issue and challenge of the high-quality production in modern chemical process.Traditional heat-driven separation processes(e.g.,fine distillation separation and selective catalytic hydrogenation separation)have the shortages of high energy consumption and low economic benefits.On the contrary,the processes with non-thermal driven separations(e.g.,adsorptive and membrane-based separations)can great-ly overcome these weaknesses.Among these adsorptive separation materials,metal-organic framework(MOF)materials own a huge various library of components/structure units.Their characters of controllable pore structures and adjustable composi-tions will bring about new opportunities for the high-efficiency refined separations.In this context,the crystals and pore parameters of MOF^(+)(MOF and its composites)materials in recent years were sorted out and summarized,the researches in the high-efficiency separation of MOF^(+)materials for C2 were analyzed,and the key issues of the design,controllable prepara-tion,and pore size control mechanism for MOF^(+)materials were focused on.In addition,the future research trend of MOF^(+)materials were also put forward.
