Georgia Tech Research Corporation
Project Number: FE0005339
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/Biomass Feed and Gasification 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.
The Georgia Tech Research Corporation will develop a detailed understanding of pyrolysis and char gasification for lignite-switchgrass blends to build kinetic and mathematical models for predicting gasification behavior by gasifying blends of lignite-switchgrass in two reactor configurations. The research is aimed at making use of the nation’s abundant coal and biomass resources to produce affordable power, fuels, and chemicals in a safe and environmentally benign manner. The production of power, fuel, and chemicals from gasification of coal-biomass blends as feedstocks has the added benefit of significantly offsetting the carbon derived from conventional fossil energy sources, thereby reducing greenhouse emissions.
