摘要
采用流动重量色谱法,测试了n-C°<sub>5</sub><sup>/</sup>C°<sub>6</sub>二元组分和n-C°<sub>5</sub>/C°<sub>6</sub>/C°<sub>7</sub>三元组分在无粘结剂的小球型5A分子筛上的吸附平衡数据。吸附的温度范围为533～653K。以统计热力学模型,对纯组分吸附实验结果进行回归,得到了模型参数,据此,对n-C°<sub>5</sub>/C°<sub>6</sub>二元组分和n-C°<sub>5</sub>/C°<sub>6</sub>/C°<sub>7</sub>三元组分的吸附平衡进行了数学描述。理论计算结果与实验结果一致。对二元组分的吸附平衡作出了相应的应用图表。
This paper was focused on the adsorption equilibrium of mixture of n-pentane, n-hexane and n-heptane on 5A molecular sieve in the range of 533～653K. The statistical thermodynamic model was used to fit the experimental adsorption isotherms. It is a good model to fit the experimental data. The isotherms of binary composition of n-pentane and n-hexane based on statistical thermodynamical model were provided.
