垃圾填埋气中的甲苯对脱碳提纯吸附剂工作性能的影响
The influence of toluene on the CO2 adsorption performance for landfill gas upgrading
摘要
Abstract
In this study,the toluene was selected as the typical volatile organic compounds (VOCs) in landfill gas.13X,5A and AC are adopted as the de-CO2 adsorbents for landfill gas upgrading process.The toluene adsorption/desorption performances on these de-CO2 adsorbents,as well as the CO2 adsorption performances on these adsorbents which had adsorbed toluene,were experimentally studied.Results show that only small amounts of toluene desorb under vacuum operation.Hence,the adsorbents are fouling with adsorbed toluene during adsorption-desorption cycles,resulting in negative impact on CO2 adsorption capacity.There are significant decreases of CO2 adsorption capacity on 13X and AC,whereas 5A has a slight decrease.It is illustrated a positive correlation between the decrease of CO2 adsorption capacity and the toluene adsorption capacity.关键词
