【摘要】 用定容型吸附装置测定了N₂、CH₄和CO₂在ZSM5上的吸附平衡数据,压力范围为0.027～190atm,温度为25、50和75℃。实验结果表明N₂和CH₄的吸附量随压力的增加而增加,在30atm附近达到饱和。CO₂的等温线有极大值,而且温度不同的等温线相互交叉。用吸附势理论关联实抢结果,三种气体的全部数据标绘点都在同一条特性曲线上。更多还原

【Abstract】 Adsorption equilibria data of N2,CH4 and CO2 on ZSM 5 were determined by a volumetric apparatus under pressure range of 0.027 to 190 atm at 25,50 and 751℃.The adsorption amount of N2 and CH4 increase with pressure,approaching saturation near 30 atm.A maximum exists on the adsorption isotherm of CO2,and the isotherms of different temperatures cross each other.Correlated by the adsorption po.ntial theory,all the data points of the three gases at various pressures and temperatures are loctaed on the same general characteristic curve.更多还原
