为了满足富氢气氛下煤直接液化基础数据的需要,选择常三柴油、四氢呋喃为混合溶剂,利用自建的循环法气体高压溶解度测定装置,测定了甲烷在柴油-四氢呋喃中的高压溶解度数据(273.45~293.75 K,2.09~7.97 MPa)。利用n-d-M-LP法以及C-G法计算了柴油的平均结构和特性参数,利用Peng-Robinson状态方程结合两种混合规则回归实验数据,得到CH4-柴油-四氢呋喃的交互参数,并估算了同条件下的溶解度数据,结果表明估算值与实验值吻合较好。 相似文献

Solubility data were first presented for methane in the mixture of ethanol-hexane at temperatures from 291.15K to 318.15K and pressures up to 12.00MPa. The experimental data were correlated by PR and PRSV equations of state with rms errors of about 0.051. The A-K and Y-W-A-K models were both used to estimate liquid molar volume under high pressure. The results were satisfactory. 相似文献

将SetaramBT2.15微量热仪温度控制系统成功引入恒定容积法,系统测定了低温条件下CH_4,C_2H_4和C_2H_6在甲醇中的溶解度。通过对CO_2在甲醇中溶解度数据的测量,验证测量装置的可靠性。结果表明:在-20—-30℃,CH_4,C_2H_4和C_2H_6在甲醇中的溶解度随温度降低而升高,随分压升高而增大,且CH_4和C_2H_4的溶解度在所测条件下符合亨利定律;而C_2H_6的溶解度在压力升高后,溶解度与压力不符合线性关系。通过PC-SAFT状态方程对所测气体溶解度进行热力学计算,结果表明PC-SAFT状态方程能够很好地关联CH_4,C_2H_4和C_2H_6在甲醇中的溶解度,并可准确描述气体溶解度随温度、压力的变化趋势,所得热力学模型可用于低碳烃吸收的工艺计算中。 相似文献

The solubility of propane in sulpholane has been determined at temperatures in the range 298‐403 K at pressures up to 17.6 MPa. The experimental results were correlated by the Peng‐Robinson equation of state, and binary interaction parameters have been obtained for this system. The parameters in the Krichevsky‐Ilinskaya equation were calculated from these interaction parameters. 相似文献

采用M30甲醇汽油与普通93#车用汽油作为研究对象,在家用轿车上分别进行了整车的动力性、燃油经济性、环保性项目对比试验。实验结果表明,与普通93#车用汽油相比,使用M30甲醇汽油的动力性能略有下降,表观油耗有所上升,HC、CO化合物排放至少降低60%,NO化合物排放基本相当。 相似文献

The solubility of methane in ethylene glycol and in diethylene glycol has been determined at temperatures in the range 25 to 125 °C at pressures up to 20.4 MPa. The experimental results were correlated by the Peng-Robinson (1976) equation of state, and interaction parameters have been obtained for these systems. Henry's constants were derived for comparison with data from the literature. 相似文献
