摘　　要：研究了自制新型吸附剂AGS的油气吸附性能,并与常用活性炭进行了对比。实验结果表明:AGS是典型的介孔材料,在较高的氮气分压下,AGS对氮气的吸附量与活性炭接近;AGS多次吸附-脱附后静态吸附量和动态吸附量均变化不大,活性炭则是显著减小;AGS对油气的吸附速率小于活性炭;吸附水蒸气后,AGS和活性炭的油气静态吸附量均有所下降,AGS的动态吸附量大于相同条件下活性炭的动态吸附量。The oil vapor adsorption properties of the self-made new-type adsorbent AGS were studied and compared with popular activated carbon. The experimental results show that： The adsorbent AGS is a typical meso-porous material and its adsorption capacity to N2 under a higher nitrogen partial pressure is close to that of activated carbon; After many times of adsorption-desorption, the static and dynamic adsorption capacities of AGS are changed little, while those of activated carbon are reduced evidently; The adsorbing speed of AGS to oil vapor is lower than that of activated carbon; When water vapor is adsorbed on the adsorbent, the static adsorption capacities of AGS and activated carbon to oil vapor are both reduced, and the dynamic adsorption capacity of AGS is greater than that of activated carbon.
