Advanced Energy Systems - Coal and Coal/Biomass to Liquids


Laboratory Scale Liquids Production and Assessment: Coal and Biomass to Drop-In Fuels


Performer: Altex Technologies Corporation

Project No: FE0010427


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 Advanced Fuels Synthesis Key Technology is focused on catalyst and reactor optimization for producing liquid hydrocarbon fuels from coal/biomass mixtures, supports the development and demonstration of advanced separation technologies, and sponsors research on novel technologies to convert coal/biomass to liquid fuels. Also included are detailed life cycle analyses to quantify the technical, economic, and environmental feasibility of producing liquid fuels from coal/biomass feedstock.

This Altex Technologies Corporation project will develop and test an integrated laboratory-scale coal-and-biomass-to-fuels system (CBTL). The impact of this project will be to develop a cost-effective gasification-based CBTL process to produce renewable liquid fuels that will provide diversity of fuel supply and energy security while resulting in lower future capital and operating costs. Specifically, this project will design and build (1) an innovative upstream process that converts the solid feed into a highly reactive intermediate and (2) a downstream process which converts the intermediate product into liquid fuel using a low-temperature catalytic system.
