摘要:

AbstractAn analytical solution has been obtained for the modified dual‐mode mobility model for a single gas proposed by Zhou and Stern and extended to a binary gas mixture to describe the pressure dependence of mean permeability coefficients for CO2and CH4mixtures in homogeneous cellulose triacetate membranes. The permeabilities calculated from the model fitted the corresponding experimental results quite well. Permeation experiments for equimolar CO2and CH4mixture in a homogeneous membrane of methyl methacrylate andn‐sbutyl acrylate copolymer were performed along with sorption experiments for pure CO2and CH4to test the applicability of the model. The experimental permeabilities were close to those calculated from the mo
