Аннотация:The membrane separation of the four-component mixture of gaseous alkanes C1-C4 is studied. Homogeneous films based on two high-permeable polymers, namely, addition-type poly[3- (trimethylsilyl)tricyclononene-7] and poly[3,4-bis(trimethylsilyl)tricyclononene-7], are used as membranes. Separation of the multicomponent mixture of hydrocarbons on these polymers follows the same trends as separation of binary mixtures CH4-C4H10 on polyacetylenes. In the presence of higher hydrocarbons, the permeability coefficients of methane decrease and the permeates become enriched with higher hydrocarbons. During separation of the multicomponent mixture, permeability coefficients P(C4H10) attein high values (up to 12000 Barrers).
