This report summarizes the progress made on the development of an integrated multistage fluidized bed retorting process (KENTORT II) during the period of January 1, 1992 through March 31, 1992. The KENTORT II process includes integral fluidized bed zones 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 design of the 50-lb/hr KENTORT II retort was completed and fabrication is ready to begin. Data from the cold-flow model of the system and operating experience from the 5-lb/hr unit were used as the basis for the design. In another aspect of the program, a study of the cracking and coking kinetics of shale oil vapors was continued. A mathematical model was implemented to characterize the important mass transfer effects of the system. This model will be eventually broadened to become a general fluidized bed coking model. In addition, experiments were performed to examine the effects of surface area, initial carbon content and steam treatment on coking activity. From the data that has been collected to-date, it appears that the coking activity of the tested substrates can be explained in terms of porosity (surface area and pore volume) and the initial carbon content of the solid.
