摘要	The perturbed-chain statistical associating fluid theory (PC-SAFT) is used to investigate the vapor-liquid equilibria for binary supercritical carbon dioxide (CO(2)) and hydrocarbon mixtures. The molecular parameters m, sigma, and epsilon/k for pure CO(2) and hydrocarbons with carbon number n <= 20 are taken from the work of Gross and Sadowski. m, sigma, and epsilon/k for n-alkanes with n > 20 are obtained by extrapolation from the linear relationships between molecular parameters and molecular weight M(w). The binary interaction parameters (k(ij)) are regressed by using the experimental data. Investigation shows PC-SAFT is able to accurately describe the vapor-liquid-phase equilibria for both CO(2)-light hydrocarbon and CO(2)-heavy n-alkane (up to C(44)) binary mixtures. When the carbon number n in each hydrocarbon ranges from 1 to 20, the regressed k(ij) increases monotonically with the increase of n. However, when n is greater than 20, there is a unique binary interaction parameter (k(ij) = 0.16) that can well describe the vapor-liquid-phase equilibria for CO(2)-eicosane, CO(2)-octacosane, CO(2)-hexatriacontane, and CO(2)-tetratetracontane binary mixtures.
