“…Fisher-Tropsch operations [Heuper, 19531 , and solvent refined coal heavy distillate have all produced tumors in animals under experimental conditions [Battelle, 19791 . Composition data [Oak Ridge National Laboratories, 1975;Battelle Columbus Laboratories, 1974;Swansiger, 1974;Electric Power Research Institute, 1975;ERDA, 19761 suggest that polycyclic aromatic hydrocarbons, heterocyclic compounds and others of carcinogenic potential are likely to be produced in liquefaction processes, primarily in high boiling fractions of product liquids (TRW Systems and Energy, 1976). The total products of hydrogenation, high-boiling distillates, centrifuged oils, chars, residues, recycled solvent oil, recycled solvent and perhaps liquid coal are potentially hazardous [Freudenthal et al, 19751 .…”

As a first step in the assessment of their possible bio-effects, coal-related materials were tested for mutagenicity in the Salmonella/microsome assay. Of three coal gasification by-products tested, only a tar was mutagenic for any of four Salmonella strains. The following liquefaction materials were mutagenic for strains TA1538, TA98, and/or TA100: A liquefaction vehicle oil and coal hydrogenation filtered liquid, separated bottoms, vacuum overhead, and vacuum bottoms. Neither powdered coal nor water produced as a by-product of the hydrogenation process was positive in the Salmonella test. No coal-related material was mutagenic for the missense mutant TA1535 or for any strain in the absence of metabolic activation provided by rat hepatic homogenates (S9). In all but one instance Aroclor 1254-induced S9 provided the maximum activation for mutagenesis. Fractionation of all samples was undertaken by serial extraction with organic solvents of increasing polarity (hexane, toluene, methylene chloride, acetonitrile). Highly mutagenic materials were found in fractions of the hydrogenation filtered liquid, vacuum overhead, and vacuum bottoms. Thus far non-mutagenic samples have not yielded mutagenic components upon fractionation.

“…products also recently has received increased interest and activity (1,6,14,(19)(20)(21)(22)24,26,30). Detailed knowledge of the composition of coal liquefaction products and other alternate fuels such as shale oils and tar sands liquids is important in evaluating conversion processes and different process conditions, in determining refining process needs, and in determining the best and most efficient end use.…”

In a continuing series of characterizaition studies, the Bartlesville Energy Research Center characterized two distil lates and a residue fraction derived from a Colstrip coal liquid produced by the Conoco Coal Development Co. molten zinc chloride catalytic liquefaction process. Procedures, established in earlier work on the heavy ends of petroleum, r were slidhtly modified and applied to these materials. The techniques include several applications of chromatography and instrument61 analyses. Although only 40 percent of the original coal liquid was submitted for analyses, the results were unique in that the portion of the coal liquid analyzed contained a significantly higher amount of monoaromatics as compared to other liquids characterized by use of these procedures.
