摘要: 通过正构碳6~碳8和异构碳8烷烃混合液在5A分子筛上的吸附实验,取得了293K、303K、313K、327K和338K温度下的吸附平衡数据.并提出了一种在能量非均匀表面上多元非理想溶液吸附等温线方程,经检验,预报结果与实验数据拟合性较好.

Abstract: On the basis of the alkane liquid mixtures adsorption experiment on 5 A molecular sieve,a new AMNLH adsorption isotherm model from multicomponent liquid mixture on the solid adsorbent was proposed.The equations were derived by assuming that :(1)the liquid bulk mixture and adsorbed phase are nonideal,and (2)the solid surface of adsorbent is energy-heterogeneous.The model was tested for a three-adsorbate system at several temperature points.
