开发了一种填充Ni/Al 2 O3催化剂的管状钙钛矿型La0.6Sr0.2Co0.8Fe3-delta膜反应器，并建立了该反应器的等温模型，用于甲烷部分氧化制合成气。随着碳空速的增加，甲烷转化率下降，CO选择性基本不变。在1098-1158 K温度范围内，甲烷转化率大于96%，CO选择性大于97%。模拟结果与实验数据吻合较好。该模型模拟了空气流量和膜反应器长度对膜反应性能的影响，为膜反应器合成气生产提供了最佳操作条件。(C)2000爱思唯尔科技有限公司版权所有。
A tubular perovskite-type La0.6Sr0.2Co0.8Fe3-delta membrane reactor packed with a Ni/Al2O3 catalyst and an isothermal model for this reactor have been developed for the partial oxidation of methane to syngas. CH4 conversion decreased and CO selectivity remained essentially constant with increasing of carbon space velocity. In 1098-1158 K, the CH4 conversion was larger than 96% with the CO selectivity larger than 97% at low carbon space velocity. The simulated results showed good agreement with the experimental data. The model simulated the effects of air flow rate and membrane reactor length on the performance of membrane reaction, which suggested optimal operating conditions for the syngas production in the membrane reactor.
