摘　　要：以DA-1,DA-2和D8三种商业树脂为吸附剂,考察了高分子树脂对典型油气废气正己烷的吸附-脱附性能.研究表明:在吸附实验中,高分子树脂对正己烷均表现出良好的吸附性能,其中DA-1和DA-2树脂具有大孔容、大比表面积和较小的孔径等特点,更有利于正己烷分子吸附;脱附实验中,真空脱附效果优于热脱附,在脱附温度达90℃,脱附时间30min,真空度为0.8时,脱附效率接近100%.The adsorption/desorption property of gasoline vapor was investigated by using the commercial polymeric resins.The results show that three kinds of commercial polymer resin were all showed great performance of adsorption of hexane,DA-1and DA-2resin showed the best adsorption capacity among them,because these two kinds of resin have big pore volume,large specific surface area and smaller pore diameter,these characteristics claim the benefit of polymeric resins to adsorb hexane molecules on the surface of resins.Then further study about the performance of the two kinds of resin to desorption,it is concluded that the vacuum desorption is superior to thermal desorption.And with the desorption temperature of 90 ℃,desorption time of 30 minutes,the vacuum degree of 0.8,the desorption efficiency is close to100%.
