CO2 Capture from Combustion of Biomass Volatiles with a Chemical-Looping Combustion Process

Conference poster, 2017

Chemical-looping combustion (CLC) is a low-cost CO2 capture technology that uses oxygen carriers – metal oxides – for oxygen transfer from air to fuel. This enables fuel oxidation without mixing fuel and combustion air. After condensation of steam, a stream of pure CO2 is obtained without the need for an active gas separation. The capture and storage of CO2 from biomass-based fuels sources make it possible to obtain so-called negative emissions – the atmosphere is cleansed from carbon dioxide. This concept of storing biomass-based CO2 could prove to be highly instrumental for a country such as Sweden, which has substantial point emissions of biomass-based CO2.
