This compendium consolidates a large quantity of diverse data which have been generated and reported by numerous investigators over the past several decades. The products for which data have been compiled are: crude petroleum, raw and hydrotreated shale oil, raw and hydrotreated whole coal liquids and intermediates, and petroleum-, coal-, and shale-derived naphtha, jet and diesel fuels and other light fuel oils, heavy fuel oils, and residua. Coal liquids addressed are those from H-Coal, EDS, SRC-I and SRC-II direct coal liquefaction processes. Sixty-six individual properties relating to the following six characterization categories are covered: general physical and chemical properties, elemental composition data, hydrocarbon compound class properties, nitrogen-, oxygen-, and sulfur-containing compounds/compound class properties, properties of various distillation fractions, and properties of 'non-primary' products and their distillation fractions. Primarily, this effort has consisted of assembling data and has not included evaluation of data quality or the development of conclusions as to similarities and differences between a synfuel and its analogous petroleum product. Limitations of the data base are noted.
