| Outline of Final Research Achievements |
In this study, we developed membrane reactors to dehydrogenate propane by integrating hydrogen-selective amorphous silica membranes with dehydrogenation catalysts, and demonstrated effective propylene production with achieving equilibrium shift due to hydrogen extraction. First we developed the hydrogen-selective amorphous silica membranes with tetramethoxysilane (TMOS), trimethoxyphenylsilane or dimethoxydiphenylsilane as precursor by the counter-diffusion CVD method, and demonstrated that all the membranes exhibited sufficient hydrogen-selective performances. Then we successfully demonstrated that the membrane reactor using the TMOS-derived membrane achieved equilibrium shift with producing propylene. However, the effect of coking on the deterioration of the membrane performance was also observed.
