; ; ;
This work is an examination of an analytical pyrolysis technique as a method for determining oil shale retorting potential. A carefully selected and prepared set of oil shale samples was evaluated by three methods: Fischer Assay, bench scale fluid bed retorting and an analytical pyrolysis method. Data are presented to show that an analytical pyrolysis based assay is an acceptable alternative to more traditional methods. This approach was also shown to be predictive of the yield of several different shales under fluid bed retorting conditions. Further, there are several distinct advantages that the pyrolysis method offers. These principally relate to sample size requirements, speed of analysis and ancillary analytical capabilities. The pyrolysis experiment described here represents only one aspect of the capabilities of this technique. The ability to carefully control the pyrolysis conditions (e.g., temperature limits, rates and residence times) should permit the evaluation of the relationship between yield and thermal treatment. The work is part of an overall Kentucky oil shale resource characterization effort.
