This report summarizes the progress made on the development of the KENTORT II process during the period of January 1, 1989 through March 31, 1989. The purpose of this program is to develop on a small scale a process to improve efficiency, process economics, and resolve environmental problems involved in the utilization of eastern US oil shale as an energy source and chemical feedstock. The process includes fluidized bed sections of pyrolysis, gasification, and combustion with combined solid/gas heat transfer among the stages. A test matrix evaluating the use of gasified shale as the heat carrier to the pyrolysis zone was continued in the 5-lb/hr, integrated reactor system. The main objective of this part of the study was to determine the effects on oil yield when the solid recycle ration and temperature were varied for a given pyrolyzer heat load. The runs utilizing the highest solid temperatures and the lowest solid recycle rates produced slightly lower oil yields. Apparently the temperature effect was great enough to override the reduced concentration of hot particles in the bed. Findings from a preliminary coking model showed a similar relationship for the conditions studied. The gasification section was not affected by the recirculation of solids as carbon gasification and sulfur removal were similar to non-recycle runs. 10 refs., 6 figs., 2 tabs.
