摘要/Abstract

摘要：

采用静态容积法分别测量CO₂和CH₄在 5A、13X 和13X-APG 沸石分子筛上的单组份等温吸附曲线，探究了吸附温度和吸附压力对吸附量的影响.实验结果表明，降低吸附温度和增加实验压力会增大吸附剂对CO₂和CH₄的吸附量，3种沸石分子筛对CO₂的吸附量均比对CH₄的大，-30 ℃时CO₂和CH₄在3种吸附剂上的饱和吸附量都最高，CO₂分别为4.94，6.52，6.35 mmol/g，CH₄的分别为3.00，3.25，3.79 mmol/g.13X-APG沸石分子筛经200 ℃、180 min加热再生后的吸附效果较好，能满足吸附剂再生要求.

Abstract:

The single-component isothermal adsorption curves of CO₂ and CH₄n zeolites 5A,13X and 13X-APG were measured by static volumetric method.The adsorption temperature and adsorption pressure on adsorption capacity were investigated.The experimental results showed that the adsorption of CO₂ and CH₄ increased as the adsorption temperature decreased and the experimental pressure increased.The adsorption capacity of the three zeolite molecular sieves on CO₂ was larger than that of CH₄.At -30 ℃,the saturated adsorption capacity of CO₂ and CH₄ on the adsorbent used was the highest,the adsorption capacity of CO₂ were 4.94,6.52，6.35 mmol/g,the adsorption capacity of CH₄ were 3.00，3.25，3.79 mmol/g.The regeneration performance of 13X-APG zeolite was at 200 ℃ for 180 mins good and met the requirement of regeneration of adsorbent.
