SYNTHESIS AND CHARACTERIZATION OF NEW AROMATIC POLYMER MATERIALS FOR GAS SEPARATION MEMBRANES

摘要

During the past few decades, gas separation systems using polymeric membranes have undergone a rapid growth since they can offer many advantages over traditional processes, namely, low energy consumption, low operating costs and high flexibility. There have been widespread gas separation applications utilizing polymer membranes, such as separation of air, removal of CO_2 from natural gas, and removing H_2 from mixtures with N_2 or hydrocarbons in petrochemical processes, etc.
