Chemical characterization, handling, and refining of SRC to liquid fuels. Quarterly progress report, January--March 1976

Results from hydroprocessing of solvent refined coal (SRC) over two commercially available catalysts are presented. By making simplifying assumptions regarding the chemistry of the conversion process, we calculate that over 40% of the consumed hydrogen goes to upgrade feed solvent to recycle solvent. The effect of hydrogen consumption on oxygen removal is discussed for CP3 where numerous conditions were evaluated. A hydrogen consumption to oxygen elimination ratio of 7/1 was observed. Similar ratios apply to both the 750 - fraction and he 750 + fraction. Results from gas-liquid chromatographic analysis of recycle solvent are presented. Dimethylindane and methylfluorene are two materials of unusual interest. Results from the high pressure liquid chromatography (HPLC) of the 750 + products are presented. Hydrotreated products have additional fine structure in the 200 (pyrene) to 300 mw (coronene) range which is absent in the corresponding fractions in the feed. Additional data on CP5 will be available in subsequent reports.
