Isopropyl alcohol dehydrogenation on modified porous membrane reactor

Isopropanol (IPA) dehydrogenation was carried out at 388-423 K in Vycor gla ss-based modified porous membrane reactor (MPMR) to confirm the result prev iously obtained for cyclohexane dehydrogenation. The result reveals that th e phenomenon of organic product concentrating in MPMR's sweep side as obser ved on cyclohexane dehydrogenation also occurs in IPA dehydrogenation. In a ddition, the overall IPA conversion in MPMR also lay between Local Fixed Be d Reactor (LFBR) and Global Fixed Bed Reactor (GFBR). However, at lower tem peratures, the difference of conversion in GFBR and MPMR is almost negligib le. This is due to the effect of surface diffusion and the characteristics of IPA dehydrogenation.
