OVERVIEW AND STATUS UPDATE OF U.S. DOD/DOE JOINT GREENHOUSE GAS EMISSIONS REDUCTIONS RESEARCH AND DEVELOPMENT LEADING TO COST-COMPETITIVE COAL-TO-LIQUIDS (CTL) BASED JET FUEL PRODUCTION

摘要

This summary presentation will provide an overview of the U. S. Department of Defense’s (DOD) and the U. S. Department of Energy’s (DOE) joint Coal and Biomass to Liquid Fuels projects. These seven projects were awarded in September 2014, and carry a total estimated cost of $25.7 million, including U.S. DOD/DOE’s cost share of $ 20 million (78%). Most of the funding comes from the U.S. Air Force ($17.3 million) while the remaining ($2.7 million) funding comes from DOE’s Office of Fossil Energy. The 7 projects are: 1.RTI International’s Breakthrough Hybrid CTL Process Integrating Advanced Technologies for Coal Gasification, Natural Gas Partial Oxidation, Warm Gas Cleanup, and Syngas-to-Jet Fuel. Total estimated cost $ 5.5 million; DOD/DOE share $4.4 million (80%). The indirect liquefaction project plans to demonstrate that the jet-fuel intermediate produced at the 1 bbl/day pilot plant is suitable for upgrading to jet fuel using commercial refinery processes, and to establish a clear commercialization path within the next 5-15 years. 2. Altex Technologies Corporation’s Green-House-Gas-Reduced Coal-and-Biomass-to-Liquid-Based Jet Fuel (GHGR-CBTL) Process. Total estimated cost $3.68 million; DOD share $2.83 million (77%). This project combines aspects of direct and indirect liquefaction technologies at the 1 bbl/day scale to produce 200 gallons of JP-8 to be tested for compliance with military jet fuel specifications. 3.Battelle’s Direct CTL for Jet Fuel Using Biomass-derived Solvents. Total estimated cost $3.76 million; DOD share $2.95 million (78.4%). This project will demonstrate a hybrid, direct coal-to-liquids jet fuel process using novel biomass derived solvents as a hydrogen source. The 1 bbl/day scale testing will generate 500 gallons of jet fuel for characterization for suitability as JP-8 without requiring blending in petroleum-derived JP-8. 4.Southern Research Institute’s Indirect Liquefaction of Coal-Biomass Mixtures for Production of Jet Fuel with High Productivity and Selectivity. Total estimated cost $3.78 million; DOD share $3 million (80%). This project uses process intensification approaches in auto thermal reforming of syngas and recycled FT tail gases and a hybrid Fischer-Tropsch (FT) catalyst/heat transfer system with a target of at least 85% of liquids with at least 60% jet fuel selectivity. Tests are planned at the NCCC operating on PRB coal/wood pellet blends containing up to 45% biomass. 5.Ceramatec’s Greenhouse Gas Emissions Reductions Research and Development Leading to Cost-Competitive Coal-to-Liquids (CTL) Based Jet Fuel Production. Total estimated cost $6 million; DOD share $4.5 million (75%). This indirect gasification project uses a Molten Salt Gasifier operated on coal water slurry and biomass, and novel desulfurization and FT reactor systems at the 1 bbl/day scale. An analysis of the cost structure of a commercial sized plant with all required equipment to generate jet fuel will be conducted. 6.Princeton University’s Design/Cost Study and Commercialization Analysis for Synthetic Jet Fuel Production at a Mississippi site from Lignite and Woody Biomass with CO_2 Capture and Storage via EOR. Total estimated cost $1.6 million; DOE share $1.17 million (73%). The project will develop a design based on a TRIGTM gasifier in an oxygen blown scenario sufficient for a Class 3 cost estimate to evaluate cost competitiveness for converting syngas via FT to the primary product being jet fuel. 7.Lummus Technology’s Feasibility Study for Conversion of Wabash River Unit 1 – IGCC to a CTL Plant. Total estimated cost $1.37 million; DOE share $1.09 million (80%). The project will develop a feasibility study for potential conversion of Wabash River Unit 1 to a coal-to-jet fuel plant producing jet fuel in compliance with EISA 2007 requirements. Several of these projects will be covered in greater detail in separate presentations to follow.
