This report contains the results of a literature survey conducted by the NASA Lewis Research Center. The survey objective was to systematically assemble existing data on the physical, chemical, and elemental composition and structural characteristics of synthetic fuels (liquids and gas) derived from coal. Contained herein are the results compiled to December 1977: (1) A general description of fuel properties, with emphasis on those properties required for synfuels to be used in gas-turbine systems for industry and utilities. (2) Descriptions of the four major concepts for converting coal into liquid fuels (i.e, solvent extraction, catalytic liquefaction, pyrolysis, and indirect liquefaction); (3) Data obtained from the literature on full-range syncrudes, various distillate cuts, and upgrade products for fuels derived by various processes - including H-Coal, Synthoil, Solvent-Refined Coal, COED, Donor Solvent, Zinc Chloride Hydrocracking, Co-Steam, and Flash Pyrolysis (The data are segregated into tables according to the processes by which they were derived, and they are also tabulated by fuel type so that fuels of similar cut can be compared for the various processes); (4) Data plots illustrating trends in the properties of fuels derived by several processes; (5) A source list and bibliography on syncrude production and upgrading programs; (6) A listing of some Federal energy contracts for coal-derived synthetic fuels production and upgrading programs. Since information on synfuels is not readily available in the literature, additional information sources were used in compiling the survey, such as monthly contractor reports from ongoing Department of Energy projects and private correspondence. These sources are noted in the data tables where applicable. (ERA citation 05:019980)
