Propane dehydrogenation on a commercial Pt‐Sn/Al2O3 catalyst in a Pd‐Ag membrane reactor is considered. A mathematical model is developed to evaluate the performance of the catalytic membrane reactor for the process of propane dehydrogenation. Design and operating conditions are systematically evaluated for key performance metrics such as propane conversion, propylene selectivity, hydrogen selectivity, and hydrogen recovery under different operating conditions. The results confirm that the high performance of the membrane reactor is related to the continuous removal of hydrogen from the reaction zone to shift the reaction equilibrium towards the formation of more propylene and hydrogen.

催化膜反应器辅助丙烷脱氢中的纯氢和丙烯联产

考虑了在Pd-Ag膜反应器中在商用Pt-Sn / Al 2 O 3催化剂上进行丙烷脱氢。建立了数学模型以评估催化膜反应器在丙烷脱氢过程中的性能。系统评估了设计和操作条件的关键性能指标,例如在不同操作条件下的丙烷转化率,丙烯选择性,氢选择性和氢回收率。结果证实,膜反应器的高性能与从反应区连续除去氢有关,以使反应平衡向更多的丙烯和氢的形成转移。
