| 摘 要： | 将PRSV状态方程应用到CO2气体在离子液体中的溶解度计算，并根据离子液体在不同温度下的密度数据，得到了PRSV状态方程用于离子液体时的方程参数，分别用与G^E模型NRTL相结合的Wong-Sandler和van der Waals混合规则来关联计算CO2气体在离子液体中的溶解度，并优化得到气体与离子液体的交互作用参数。其计算结果的平均相对误差分别为9．45％和6．60％。

| Abstract: | The Peng-Robinson equation of state modified by Stryjek and Vera(PRSV) was extended to model the gas solubility of carbon dioxide in ionic liquids.The parameters of ionic liquids,which were used in PR EoS were obtained from the density data of ionic liquids,The van der Waals and Wong-Sandier mixing rule combined with the NRTL model were used to correlate the solubility of carbon dioxide in the ionic liquids,which the average absolute deviations of the calculated results are 9.45% and 6.60%.Also,the optimized interaction parameters of gas and ionic liquids were obtained. |
