Virginia Polytechnic Institute and State University
Project Number: FE0005476
Program Background and Project Benefits
The Department of Energy (DOE) is committed to supporting research focused on making use of the nation's coal and biomass resources. The Coal and Coal Biomass to Liquids (C&CBTL) Technology Program at DOE's National Energy Technology Laboratory (NETL) is developing advanced technologies to remove technical barriers that will foster the commercial adoption of coal and coal/biomass gasification technologies for the production of affordable hydrogen and liquid fuels (such as gasoline, diesel, aviation, and military fuels). The hydrogen can be used in advanced systems for efficient power generation produced with near-zero emissions and with the potential to significantly reduce greenhouse gas emissions. The synthesis gas (syngas) produced by the gasification of coal and coal/biomass mixtures can be converted by chemical processes to generate clean liquid hydrocarbon fuels. To successfully complete the development of C&CBTL technologies from the present state to the point of commercial readiness, the C&CBTL Program efforts are focused on two Key Technologies: (1) Coal/Biomass Feed and Gasification, and (2) Advanced Fuels Synthesis.
The Coal and Coal Biomass to Liquids Key Technology is advancing scientific knowledge of the production of liquid hydrocarbon fuels from coal and/or coal-biomass mixtures. Activities support research for handling and processing of coal/biomass mixtures, ensuring those mixtures are compatible with feed delivery systems, identifying potential impacts on downstream components, catalyst and reactor optimization, and characterizing the range of products and product quality from the fuels conversion processes. Liquid fuels produced from coal/biomass feedstock not only reduce the nation’s dependency on foreign oil but also are cleaner burning than comparable petroleum products.
The Virginia Polytechnic Institute will characterize the chemical kinetics and reaction mechanisms of co-gasification fuels to determine their key reactive properties by conducting bench- and pilot-scale gasification experiments over arrange of temperatures, will develop kinetic modeling to predict product formation, and will develop computational fluid dynamics models that incorporate the chemical kinetics for coal-biomass gasification. This work will help improve gasifier design so that coal can be used more efficiently, biomass resources can be used for energy production, and unwanted emissions can be decreased.
