摘　　要：采用容量法分别测量CH4、CO和CO2在5A分子筛上的等温吸附曲线,探究吸附温度和吸附压力对CH4、CO和CO2吸附量的影响。实验结果表明,吸附量随着吸附压力的上升逐渐增大。设定吸附温度在30℃、50℃和70℃时,5A分子筛在30℃时对CH4吸附量最大,为13.60cm3·g-1;对CO和CO2吸附量均在50℃时呈现最大值,分别为17.68cm3·g-1和94.38cm3·g-1。而吸附温度70℃时,对3种气体的吸附量均减小。Adsorption isothermal curves of CH4,CO and CO2 on 5A zeolite were measured by volumetric method.The effect of adsorption temperature and adsorption pressure on adsorption capacity was discussed.The experimental results showed that the adsorption capacity of CH4,CO and CO2 increased as the experimental pressure increased.When the adsorption temperature was 30℃,50℃and 70℃,the largest adsorption capacity of CH4 on 5A zeolite was 13.60 cm3·g-1 at 30℃;the largest adsorption capacities of CO and CO2 were all at 50℃,which were 17.68 cm3·g-1 and 94.38 cm3·g-1,respectively.The adsorption capacities of the three gases were reduced at 70℃.
