Ethanol steam reforming over a Co/Al₂O₃ catalyst was studied theoretically in a catalytic PdAg membrane reactor (CMR). A mathematical model has been developed to elucidate the behavior of CMR by taking into account the chemical reactions, heat and mass transfer phenomena. The effect of operating parameters on the performance of CMR has been evaluated in terms of ethanol conversion, hydrogen recovery and hydrogen yield. The results revealed the high performance of this configuration is related to the continuous removal of hydrogen from the retentate side, shifting the reaction equilibrium towards hydrogen formation. Sensitivity analysis of operating parameters indicate that ethanol conversion is favored at higher temperatures, pressures, sweep ratios and feed molar ratios. Moreover, increasing the feed molar ratio enhances the ethanol conversion, and decreases the hydrogen recovery due to reduction of partial pressure of hydrogen and consequently decreasing the driving force for the hydrogen permeation through the membrane.

理论上在催化钯中研究了Co / Al ₂ O ₃催化剂上的乙醇蒸汽重整银膜反应器（CMR）。通过考虑化学反应，传热和传质现象，开发了一个数学模型来阐明CMR的行为。已根据乙醇转化率，氢气回收率和氢气产率评估了操作参数对CMR性能的影响。结果表明，这种配置的高性能与从渗余物侧连续除去氢有关，从而使反应平衡向氢的形成转移。操作参数的敏感性分析表明，在较高的温度，压力，吹扫比和进料摩尔比下，乙醇转化率较高。此外，提高进料摩尔比可提高乙醇转化率，
