The objective of this Ohio State University project is to further demonstrate the technical and economic advantages of chemical looping gasification (CLG) for power generation and for synthesis of transportation fuels and other high value chemicals from coal. Specifically, the research team aims to (1) improve oxygen carrier performance, (2) demonstrate at bench-scale that the CLG process can achieve greater than 98 percent coal conversion, (3) demonstrate the effects and fates of contaminants, (4) develop a sub-pilot-scale cold-flow model, and (5) provide a comparative techno-economic analysis that establishes the feasibility and attractiveness of the CLG system.
Ohio State University will demonstrate the technical and economic advantages of a chemical looping gasification (CLG) process in context of integrated gasification combined cycle (IGCC) and coal-to-liquid plants. Project objectives are to 1) improve oxygen carrier performance, 2) demonstrate the CLG process at bench-scale to achieve greater than 98% coal conversion, 3) identify the effects and fates of sulfur, nitrogen, and other trace contaminants, 4) model cold-flow at sub-pilot scale, and 5) perform a comparative techno-economic analysis that validates the feasibility and attractiveness of the CLG system. Commercialized CLG technology is expected to improve the efficiency of coal-based gasification systems for both electricity generation and liquid fuels production while minimizing their carbon footprints.
