ABSTRACT
The prepared different components municipal solid wastes based carbons were used to investigate the adsorption of CO2. The optimum conditions for CO2 adsorption were investigated firstly. And then, the CO2 adsorption performance of different components based carbon adsorbents were compared with each other under the optimum parameters. The results illustrated that the triple components (pinewood, acrylic textile, and tire) based carbon exhibited the best adsorption performance, which is 1.522 mmol/g and its physical prosperity was also conducted to interpret the adsorption mechanism. Besides, to further approach to the actual gas, the influence of additional O2 and SO2 on CO2 adsorption properties of ternary-component-based carbon was investigated. The results illustrate that O2 concentration exerts little effect on adsorption capacity. SO2 plays the dominated role in the competitive adsorption effect.
