Abstract

The excess adsorption isotherms of pseudocumene from solutions in n-octane in zeolite NaX have been measured at 303.15, 338.15 and 363.15 K using the conventional static method. The absolute (limiting) adsorption values of the pure components have been measured by the pycnometric method. The absolute adsorption isotherms for the system have been calculated using a non-fitting three parameter equation, based on the modified Dubinin–Radushkevich one. The absolute adsorption data are then used for estimation of average adsorbate density and activity coefficients of the components in the adsorbed phase.

拟枯烯 + 正辛烷 + 沸石 NaX 系统的绝对吸附等温线：吸附相活性系数的测定

摘要

从溶液中假枯过量吸附等温线ñ -辛烷中的NaX沸石已经在303.15，338.15和363.15说明使用常规的静态方法测定。纯组分的绝对（极限）吸附值已通过比重瓶法测量。基于修正的 Dubinin-Radushkevich 方程，系统的绝对吸附等温线已使用非拟合三参数方程计算。然后将绝对吸附数据用于估计吸附相中组分的平均吸附物密度和活性系数。
