| 摘 要： | 对不同VOCs气体二元吸附平衡进行了研究。结果表明,对于甲苯-苯、甲苯-乙酸乙酯、甲苯-丙酮、丙酮-乙酸乙酯及苯-丙酮二元吸附体系,吸附过程存在置换现象,即随着高沸点组分在床层内吸附量的逐渐增加,相对挥发性大的低沸点组分更易脱附,出现高沸点组分置换低沸点组分的现象,表现为被置换组分的穿透曲线上出现峰值;但对于苯-乙酸乙...

| Abstract: | The binary adsorption equilibrium of different VOCs gases was studied.Results show that for the binary adsorption systems,as of toluene-benzene,toluene-ethyl acetate,toluene-acetone,acetone-ethyl acetate and benzene-acetone,displacement phenomena take place in the adsorption processes.With the increase of adsorbed amount of high boiling point components in adsorber,the low boiling point components desorb more easily,and displacements from high boiling point components to low boiling point components occur,w... |
