    • This invention relates to a method for effectively separating an unsaturated hydrocarbon from a feedstock containing at least two similar unsaturated hydrocarbons comprising passing the feedstock over one side of an ionopore membrane charged with a facilitator having an affinity for each of the at least two similar unsaturated hydrocarbons and recovering from a second side of the membrane permeate containing predominantly one of the at least two similar unsaturated hydrocarbons, the similar unsaturated hydrocarbons being selected from the group consisting essentially of aromatic, alkene, and diene hydrocarbons.This invention further relates to a method for achieving liquid phase separation of at least two competing components from a feedstock containing the components such that the separation factor for the competing components is at least about 4 times the separation factor calculated when permeating single components using the same membrane and under the same conditions.
    • 本发明涉及一种从含有至少两种类似的不饱和烃的原料有效分离不饱和烃的方法,包括使原料在离子载体膜的一侧上通过,该离子核膜装有对每种至少两种相似的不饱和烃具有亲和性的促进剂 并且从主要包含至少两种相似不饱和烃中的一种的膜渗透物的第二侧回收,所述相似的不饱和烃选自基本上由芳烃,烯烃和二烯烃组成的组。 本发明还涉及一种用于从含有组分的原料获得至少两种竞争组分的液相分离的方法,使得竞争组分的分离因子是使用相同组分渗透单一组分时计算的分离因子的至少约4倍 膜和在相同条件下。
