摘要
在298.2 K温度和13.3~101.3kPa压力范围内,测定了乙烯、乙烷和 二氧化碳单组分气体在AE型吸附剂上的吸附平衡数据.用空位溶液理论 模型对数据进行分析,并用顶点收敛法进行回归计算,得到了空位溶液理论 模型的四个物性参数:极限吸附量,享利常数b,两个威尔逊参数A13和 ;用空位溶液理论对单组分等温线进行了很好地描述,使模型与全部压力 范围内的纯组分等温线得到很好地拟合.
Simple component equilibrium data for ethylene ,ethane and carbon dioxide on AE have been determined at 298. 2 K and pressures from 13. 3 to 101. 3 kPa. The adsorption data have been analyzed in terms of the vacancy solution model isotherm. The model provides an excellent correlation of pure component isotherms over the entire pressure range. It is shown that equilibrium data for the adsorption of single gases were correctly predicted by the four model parameters (limiting molecular Volume ,Henry's constants Li1 and two Wilson's parameters (A13 ,A31) derived from analysis of the pure component isotherm. The experimental results were given the reasonable explaination in terms of the adsorbent physichemical properties.
