Membrane separation appears to be a promising candidate because of low energy consumption, compact unit, simple operation and low environmental impact. Therefore, strong interest exists in the synthesis of membranes that exhibit both higher permeabilities and higher selectivities than presently available polymers. The performance of zeolite membranes is far superior to any other membrane previously reported in both of pervaporation and vapor permeation. Thus, A type and T type zeolite membrane modules have been put to practical use for dehydration of organic liquids. Here, new applications of the zeolite membrane are introduced for hybrid system of chemical reaction and membrane separation, such as pervaporation membrane reactor for esterification reaction and pervaporation catalytic reactor for oxidation reaction by TS-1 membrane.
