摘要
将无机 膜反应 器应用于 丙烷部分 氧化制 丙烯醛的 反应 中,考 察了 不同 膜操 作方 式和 反应条件的 影响. 实验结 果表明, 采用 P P O R 膜操 作方式 ,即丙烷从 渗透侧 通入,氧气 从反应 侧通入,丙烷可获 得较大 的自由活 化空间, 避免与气 相氧反 应,因此提 高了部 分氧化反 应的选择 性. 采用分别进样的 膜反应 ,丙烯醛产 率可比 混合进样 的固定 床反应高 出达3
Inorganic membrane reactor was used in selective oxidation of propane to acrolein. The reaction performance was measured under different operation modes and different reaction conditions. As the results shown, it could be found that the PPOR (propane lead in from permeation side, oxygen and nitrogen from reaction side), PROP (propane lead in from reaction side, oxygen and nitrogen from permeation side), and BPS (both of reactants lead in from permeation side) operation modes performed better than BRS (both of reactants lead in from reaction side, ie conventional fixed bed reactor) mode. The best performance was obtained under PPOR operation mode, because there was larger space for propane activation, and propane could not directly react with the adsorbed oxygen.
