Isopropanol (IPA) dehydrogenation was carried out at 388-423 K in Vycor glass-based modified porous membrane reactor (MPMR) to confirm the result previously obtained for cyclohexane dehydrogenation. The result reveals that the phenomenon of organic product concentrating in MPMR's sweep side as observed on cyclohexane dehydrogenation also occurs in IPA dehydrogenation. In addition, the overall IPA conversion in MPMR also lay between Local Fixed Bed Reactor (LFBR) and Global Fixed Bed Reactor (GFBR). However, at lower temperatures, the difference of conversion in GFBR and MPMR is almost negligible. This is due to the effect of surface diffusion and the characteristics of IPA dehydrogenation.
