【摘要】 本文用定容型吸附量测定装置测定了N₂,CH₄,CO和N₂O在沸石MS-13x上的高压吸附平衡数据。平衡压力从0.26～81.20atm,温度为25℃,50℃和75℃。同时测定了N₂在0和-196℃下的低压吸附平衡数据。实验结果表明N₂,CH₄和CO吸附最随压力增加而增加,在40atm附近达到饱和。N₂O的吸附等温线在20atm附近出现了极大值,且不同温度的吸附等温线呈现了相互交叉的现象。本研究所得的全部吸附平衡数据。用扩展了的吸附势理论进行关联,所有的点几乎都落在同一曲线上。更多还原

【Abstract】 The adsorption equilibria of N₂, CH₄, CO and N,O on molecular sieve 13X are measured with a Constant volume apparatus under 0.26 to 81.2 atm at 25, 50 and 75℃, and adsorption epuilibria of N₂ below atmosphere at 0 and-196℃ are also determined. The experiment shows that adsorption amount of N₂, CH₄ and CO increases with pressure until approaching saturation at about 40 atm. A maximum exists at about 20 atm on the isotherm of N₂O, and the isotherms at different temperatures cross each other.All the data obtained in this work are correlated by the extended adsorption potential theory, and almost all experimental points are located on the characteristic curve.更多还原
