Partial gasification for CO2 emissions reduction

Abstract

From the perspective of energy security and environmental sustainability, highly effective uses for fossil fuel in energy industries are demanded. Power plants having integrated gasification combined cycle (IGCC) with advanced configurations are being developed worldwide to use coal and biomass more efficiently and thus cleanly. Gasification forms the major component within the IGCC systems and has the best fuel flexibility of any of the advanced technologies for power production, with the current technology well adapted to use biomass and other low-value feedstock that have high-ash residues (Liu and Niksa, 2004). Gasification also provides an opportunity to control and reduce gaseous pollutant emissions, and a lowest cost approach to concentrate the carbon dioxide at high pressure to facilitate sequestration (Trapp, 2005).
