The development of an integrated multistage fluid bed retorting process. [KENTORT II process--50-lb/hr]
This report summarizes the progress made on the development of an integrated multistage fluidized bed retorting process (KENTORT II). The KENTORT II process includes integral fluidized bed zone for pyrolysis, gasification, and combustion of the oil shale. The purpose of this program is to design and test the KENTORT II process at the 50-lb/hr scale. The work performed during this year involved projects that will contribute physical and chemical data for the final design of the 50-lb/hr retort. A cold-flow model of the 50-lb/hr retort was built and tested. The unit demonstrated stable operation and proper fluidization of all beds. Good control of solid recirculation up to the maximum design rate for each loop (200 and 500 lb/hr, respectively) was achieved simultaneously. Basically, the cold-flow model is completely operational and translation of the cold-flow design parameters to the design of the retort is ready to begin. In another aspect of the program, a study of the cracking and coking kinetics of shale oil vapors passed over processed shales was initiated. The addition of a mass spectrometer to the system to monitor total carbon, nitrogen and sulfur evolution in real-time was successful. Coking activities of processed shales were ranked as follows: combusted shale > gasified shale > pyrolyzed shale. Arrangements for conducting an evaluation of KENTORT-derived oil for asphalt applications were finalized and testing was initiated.
