Abstract: In this paper, the characteristics of polymeric membrane catalytic contactor, catalytic membrane materials and preparation methods are summarized. Compared with the traditional catalytic reactor,polymeric membrane catalytic contactor has the advantages of compact structure,simple technology and operation process,high catalytic activity,high reaction rate and high conversion rate. Active nanoparticles or groups can be easily introduced onto molecular backbone and side chains which are bonded with lots of functional groups. The preparation methods of polymeric catalytic membrane mainly include hybrid method,dipping method and chemical grafting method. Diffusion process is the controlling step of catalytic reaction process of polymeric membrane catalytic contactor. The whole process includes internal diffusion and external diffusion. Some problems deserving further research and application prospects of polymeric membrane catalytic contactor are presented. Catalytic efficiency and service life need to be further improved;novel polymeric membrane materials need to be developed;membrane fouling and membrane catalytic deactivation problems need to be resolved;basic issues, such as establishing kinetic model of polymeric membrane catalytic reaction need to be further studied.
