Characterization of a Colstrip coal liquid derived from the zinc chloride hydrocracking process

Abstract

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.

The Composition of Liquids From Coals of Different Rank

“…Details of the procedures have been reported previously (12,14,16,17). Analyses of subfractions of aromatic concentrates separated by gelpermeation chromatography (GPC) were performed on a low-resolution CEC 21-103C mass spectrometer (MS) using low-ionizing-energy electrons to produce predominantly molecular ions.…”
