在388-423 K温度下，在Vycor玻璃基改性多孔膜反应器（MPMR）中进行了异丙醇（IPA）脱氢反应，以证实先前获得的环己烷脱氢反应的结果。结果表明，在环己烷脱氢反应中观察到的有机产物集中在MPMR扫掠侧的现象在IPA脱氢反应中同样存在。此外，MPMR反应器中IPA的总转化率也介于局部固定床反应器（LFBR）和整体固定床反应器（GFBR）之间。然而，在较低温度下，GFBR和MPMR的转化率差异几乎可以忽略不计。这是由于表面扩散效应和IPA脱氢的特性造成的。
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.
