Outline of Final Research Achievements

Based on the membrane technology of porous silica membranes, this research aims to (1) develop and improve the separation functionality: improvement of the selectivity and permeability of the porous silica separation layer by using various membrane materials and preparation processing, (2) develop the membrane reaction functionality: development of a membrane reactor combining a reaction catalyst and separation membrane and its application to membrane reactions (dehydrogenation and dehydration reactions, and transesterification reactions), and (3) evaluate the membrane reactor systems: evaluation of the system of membrane reaction such as optimum operating conditions. This research will clarify the process intensification by membrane reactors experimentally and theoretically.
