通过实验和模拟研究了催化剂用量、膜管直径和渗透速率对多孔膜反应器性能的影响。实验中使用多孔Vycor玻璃膜反应器。为了研究催化剂用量的影响，膜反应器的渗透侧填充了与进料侧相同的催化剂，即 0.5 wt% Pt/Al2O3。 Ω，即渗透侧催化剂的体积分数，在0％至100％之间变化。据观察，总转化率随着 Ω 值的增加而增加。为了研究膜管直径对改进多孔膜反应器（MPMR）性能的影响，采用不同膜管直径进行了实验和模拟。结果表明，存在实现最大转化率的最佳膜管直径。它还表明，在 MPMR 中，膜表面积和 VT/VS 比值比膜厚度更重要。为了研究渗透率的影响，进行了一些模拟。结果表明，渗透速率显着影响多孔膜反应器的性能。通过设计合适的参数，可以在MPMR的渗透侧获得高纯度的有机产品。
Effects of catalyst amount, membrane tube diameter, and permeation rate on porous membrane reactor performance were investigated through experiments and simulations. Porous Vycor glass membrane reactors were used in the experiment. To study the effect of catalyst amount, permeation side of a membrane reactor was filled with the same catalyst as that used in the feed side, i.e. 0.5 wt% Pt/Al2O3. The Ω, that is, a volume fraction of a catalyst in the permeation side was varied from 0% to 100%. It was observed that overall conversion increases with the Ω value. To study the effect of membrane tube diameter on the performance of a modified porous membrane reactor (MPMR), experiment and simulation using different membrane tube diameters were conducted. The results show that there are optimum membrane tube diameter to achieve maximum conversion. It also reveals that in an MPMR, membrane surface area and ratio of VT/VS are more important than membrane thickness. In order to study the effect of permeation rate, some simulations were conducted. The results show that permeation rate significantly affects the performance of porous membrane reactors. By designing appropriate parameters, it is possible to achieve high purity organic product in the permeation side of MPMR.
