Advances in CO2 Capture using Absorption and Adsorption Technology: A Review

The CO2 capture from flue gas which is emitted from the power plants, is one of the important way to reduce greenhouse gases. The flue gas from coal-fired power stations can be removed by Absorption process using solvents and by Adsorption processes using solid sorbents. This article reviews the progress made in CO2 separation completely. A variety of promising sorbents such amine, ammonium, activated carbonaceous materials, microporous/ mesoporous lithium based silicates, carbonates for the removal of CO2 from the flue gas streams have been reviewed. A wide ranging review and analysis of the literature of CO2 has been carried out to update the recent progress. A comparison of different sorbents efficiency is made with current research efforts to progress of carbon capture.
