A novel approach to the removal of CO{sub 2}

摘要: The removal of CO{sub 2} from gas streams is becoming increasingly significant in the field energy production. A porous monolithic activated carbon material (CFCMS) has been developed that both strong and rigid, yet permeable, thus offers little resistance to free-flow fluids. a unique combination properties, including reasonable compressive strength, electrical conductivity, large micropore volume, adsorption capacity. At 30{degrees}C atmospheric pressure, CFCMS uptake >100 mg/g. reduced at elevated temperatures, dropping {approximately}40 mg/g 100{degrees}C. However, increases substantially with such 25{degrees}C 58 bar mass adsorbed >490 ability selectively remove 2}/CH{sub 4} mixture demonstrated series breakthrough experiments. properties exploited effect rapid desorption under influence low applied dc voltage.
