摘要：通过合成8种多孔二氧化硅材料,并用所制备的多孔材料作为吸附剂,考察了其对苯蒸汽的吸附性能。实验结果表明:饱和吸附量主要取决于吸附剂材料孔径和比表面积的大小;骨架的有机化将有利于其对苯蒸汽等有机分子的吸附;比表面积较大的二氧化硅气凝胶对苯的吸附性能最好。在结构特点上总结了影响多孔材料吸附性能的众多因素,为作业场中苯的吸附处理提供借鉴。
Acute poisoning of benzene waste gas makes its treatment become very important. The materials with large specific surface area,good adsorption capacity and abundant reserves properties of porous materials are the most commonly used adsorbents. 8 kinds of porous silica were synthesized and used as adsorbents in benzene adsorptions. The experimental results showed that： the saturated adsorption amount mainly depends on the adsorbent pore size and specific surface area size. Organic skeleton is beneficial to the adsorption of benzene and other organic molecules. Silica aerogel has the best adsorption property because of its high surface area size. The factors which affect the adsorption amounts were systemically discussed. The conclusion is very important for dealing with benzene vapor practically.
