用于C1化学具有选择吸附—脱附特性的气体分离膜

Gas Separation Membrane with Selective Adsorption Desorption Characteristic for C_1 Chemistry

摘要: 本工作研究了吸附剂、催化剂等固体添加物混入微孔聚砜膜中对C_1化学用原料气-H_2和CO的选择透气性的影响,普遍的结果是显著地提高了膜对气体的分离因子,且与吸附剂、催化剂的化学、物理性质有一定关系。因此,气体的渗透过程除了有诺森流和粘性流外,还可能生成吸附态过渡络合物,影响气体的吸附-脱附能力而提高了分离因子,提出了过渡吸附态的气体促进输送机理。

Abstract: The influences of adsorbents and catalysts incorporated into polysulfone membrane on gas permselectivities were studied. A remarkable increase occurs with regard to the separation factor of that membrane to H_2 and CO which are the feed gases in C_1 Chemi
