Coal liquefaction process solvent characterization and evaluation: Progress report, 1 April--30 June 1986
Conoco Coal Research Division is characterizing samples of direct coal liquefaction process oils based on a variety of analytical techniques to provide a detailed description of the chemical composition of the oils to more fully understand the interrelationship of process oil composition and process operations, to aid in plant operation, and to lead to process improvements. The approach taken is to obtain analyses of a large number of well-defined process oils taken during periods of known operating conditions and known process performance. A set of thirty-one process oils from the Hydrocarbon Research, Inc. (HRI) Catalytic Two-Stage Liquefaction (CTSL) bench unit was analyzed to provide information on process performance. The Fourier-Transform infrared (FTIR) spectroscopic method for the determination of phenolics in cola liquids was further verified. A set of four tetahydrofuran-soluble products from Purdue Research Foundation's reactions of coal/potassium/crown ether, analyzed by GC/MS and FTIR, were found to consist primarily of paraffins (excluding contaminants). Characterization data (elemental analyses, /sup 1/H-NMR and phenolic concentrations) were obtained on a set of twenty-seven two-stage liquefaction oils. Two activities were begun but not completed. First, analyses were started on oils from Wilsonville Run 250 (close- coupled ITSL). Also, a carbon isotopic method is being examined for utility in determining the relative proportion of coal and petroleum products in coprocessing oils.
