This fuel processing/quality study provides a data base that can be used for assessing trade-offs between advanced gas turbine technology and liquid fuel quality and to help guide the development of specifications for future synthetic fuels anticipated for use in the time period 1985 through 2000. The study has quantified the cost and energy efficiency required for achieving various fuel characteristics and purity levels in coalderived liquids, shale oils, and residual oils processed through modified existing refineries or new refineries. The study also has developed cost data associated with using onsite fuel treatment, such as blending, washing, and exhaust gas cleanup, which allows the turbine user to make use of low-quality fuels. Minimum cost paths have been identified considering the trade-offs between refinery processing and on-site treatment. This paper highlights the results, methodologies, and assumptions of two contracted studies managed by the National Aeronautics and Space Administration for the U.S. Department of Energy. The work was performed under Interagency Agreement DE-AI01-77ET-13111.
