CO2 capture by electrothermal swing adsorption with activated carbon fibre materials

This paper presents progress made in CO2 capture by electrothermal swing adsorption (ESA) with activated carbon fibre materials. The current barrier in CO2 capture and storage is the high cost of CO2 separation and capture. CO2 capture by electrothermal swing adsorption can potentially be more energy-effective than conventional temperature swing adsorption (TSA) and pressure swing adsorption (PSA), thus reduces CO2 capture cost. Activated carbon fibre materials have been utilised as the adsorbents due to their demonstrated capabilities for CO2 capture and their good electrical conductivity. This paper reviews the major results in the literature in the development of activated carbon fibre materials and the process of ESA. It also suggests future research directions in CO2 capture by electrothermal swing adsorption.
