Post‐Combustion Carbon Capture

Abstract

CCS, Carbon Capture and Storage, is considered a promising technology to abate CO2 emissions from point sources. The present review deals with the principle of postcombustion capture techniques, including thermal or pressure swing principles, adsorption or absorption, and electrical swing or membrane separation processes.Opportunities and challenges are assessed. In the first section of absorption processes, several commercial technologies are compared, and complemented by the aqueous or chilled ammonia (NH3) process, and a dual or strong alkali absorption. The second section deals with adsorption where fixed beds, circulating fluidized beds and countercurrent bed configurations will be discussed, with special focus on the different adsorbents ranging from zeolites or activated carbon, to more complex aminefunctionalized adsorbents, nanotubes or metal organic frameworks (MOFs), and alkali-

“…The combustion of fossil fuels contributes to over 80% of the total energy produced in the world and releases 3 × 10 13 kg of CO 2 every year, 1 accounting for 91% of anthropogenic CO 2 emissions. 2 Despite the transition into green energy, fossil fuel combustion is still expected to contribute to energy production for the next few decades.…”
