Pyrolysis and hydropyrolysis of Kentucky oil shale using super-critical toluene as the solvent was studied in a 300-cc stirred-batch reactor. Organic carbon conversions in excess of 160% Fischer Assay were obtained in less than 30 minutes for those reactions occurring above 400 C with hydrogen atmospheres. It was found that the overall conversion of organic compound to oil and gas products could be adequately modeled using a second-order irreversible rate expression. Reactions occurring at 460 C and 300 psig hydrogen partial pressure could be considered instantaneous, yielding organic carbon conversions of 185% Fischer Assay. The effects of hydrogen partial pressure was found to be significant for reactions occurring above 400 degrees C. The selectivity for total carbon conversion to oil was shown to be high, however this value was dependent on the reaction temperature and reaction time. A characterization comparison between a pyrolysis oil produced by Dravo Engineers, Inc. and the oil produced from a run performed at 440 C for 10 minutes demonstrated that the oils were remarkably similar in their chemical make-up.
