Research Institution
Consumption of coal and other fossil fuels is a major contributor to emission of carbon dioxide and criteria pollutants. Coal gasification technologies equipped with carbon capture and sequestration (CC & amp;S) technology can help address both these problems. However, current coal gasification concepts suffer from a combination of low efficiency and high capital cost. TIAX proposes to investigate the feasibility of a coal-CO2 (liquid) slurry feed for coal gasification by conducting a bench-scale evaluation of critical parameters that influence the solids carrying capacity of the slurry and the resilience of high-moisture content coals. The proposed approach will enable the use of low-rank coal (LRC) feedstocks, increase the efficiency, and reduce the operating costs of coal gasification systems, thereby encouraging U.S. industry to implement environmentally superior gasification-based processes.Commercial Applications and Other Benefits: TIAXs coal-CO2 slurry system would be marketed for use in coal gasification plants, which can be used to produce electricity, gaseous and liquid fuels, and chemicals in an environmentally friendly way. If fully adopted, the proposed technology could reduce greenhouse gas emissions by 17 million metric (MM) tons, NOx emissions by 0.5 MMtons, and SO2 emissions by 2 MMtons per year, while offering $18B in savings and reducing CO2 mitigation costs from $23 to $14 per ton of avoided CO2.
