【摘要】 研究了国产改性的３种ＺＳＭ５分子筛从二氯苯异构体混合液中选择吸附对二氯苯的平衡规律．结果表明，３种分子筛对对二氯苯的选择吸附能力为ＨＺＳＭ５＞ＦｅＺＳＭ５＞ＬｉＺＳＭ５，对、邻位ＤＣＢ单组分的吸附等温线均可用Ｌａｎｇｍｕｉｒ模型表示，而ＤＣＢ双组分混合液的吸附等温线却不能用Ｌａｎｇｍｕｉｒ模型表示，作为非理想吸附体系，其非理想吸附程度可用活度系数来表征．更多还原

【Abstract】 This paper studied adsorption equilibrium of liquid mixture of dichlorobenzene(DCB)isomers on three kinds of zeolites of ZSM 5.It has shown that selective adsorption capacity for DCB is HZSM 5>FeZSM 5>LiZSM 5,and single adsorption isotherm of p DCB and o DCB can be expressed in Langmuir model.However,the binary adsorption isotherms of DCB liquid mixture can not represented by Langmuir model.As a nonideal adsorption system,the character of nonideal adsorption can be described by activity coefficients.更多还原
