Advance on the Inorganic Membrane Reactors

Membrane reactor is identified as an integral unit equipment with the dual functions of separation and reaction,which can intensify chemical reactions by the synectic effects of separation and reaction.They are promising in the reactions of hydrogenation,dehydrogenation,decomposition and oxidation,etc.Membrane materials are one of the most important factors in determination of the performance and application of a membrane reactor.In this article,the future development direction of the existent two kinds of inorganic membrane reactors,i.e.,dense membranes and porous membranes,are addressed with the respect of characteristics of membrane materials.It is concluded that the research on the advanced membrane materials with high performance,anti-foul and easy of assembly should be deve-loped,and the key technology and basic principles of mass and heat transfer of inorganic membranes should also be addressed,in order to promote the widely application in industry.
