| 摘 要： | 采用模板剂法制备了孔道规整、大比表面积的2种介孔分子筛MCM-41和SBA-15,并以甲苯、二甲苯、三甲苯为吸附对象,考察了介孔分子筛动态吸附VOCs的性能.结果表明,增加VOCs分子尺寸和浓度,降低床层温度可大幅提高介孔分子筛吸附性能.SBA-15由于介孔壁上的微孔结构适合吸附低浓度、小分子VOCs;MCM-41更适合吸附高浓度、大分子VOCs.TPD脱附试验表明,VOCs在介孔材料表面150℃下就能基本脱附完全.

| Abstract: | The MCM-41 and SBA-15 mesoporous molecular sieves with ordered structure and high surface area were synthesized by template method. Dynamic adsorption of toluene,o-xylene,mesitylene on the mesoporous molecular sieves were studied. The adsorption of VOCs on mesoporous molecular sieves increased with increasing molecular size and concentration of VOCs,but decreased with increasing bed temperature. Because of the microporous structures which on the pore wall,the SBA-15 was appropriate in adsorption of low conc... |
