摘要

本文用定容型吸附量测定装置

在压力为3.04×10~3至1.43×10~7Pa范围内

温度为—196、0、25、50和75°C下测定了N_2、Ar、CH_4、CO_2和N_2O等气体在氢型丝光沸石上的吸附平衡数据.实验结果表明:N_2、Ar和CH_4的吸附量随压力增加而增加

直到在6.08×10~6Pa附近达到饱和;CO_2和N_2O的吸附等温线出现了极大值

且不同温度同一吸附质的吸附等温线出现了相互交叉的现象.用扩展了的吸附势理论进行关联

取得了满意的结果.

Abstract

The adsorption equilibria of N2

CH4

CO2 and N2O on H-Mordenite were studied with a constant volume apparatus under pressure from 3.04×103 to 1.43× 107 Pa at -196

50 and 75℃. The adsorption amount of N2

Ar and CH4 increased with pressure until approaching saturation at about 6.08× 106Pa. A maximum existed on the adsorption isotherm of CO2 and N2O

and their isotherms at different temperatures crossed each other. All the data obtained in this work can be well correlated by the extended adsorption potential theory. All experimental points are located on the same characteristic curve.
