This book was released on 1992 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: This report summarizes the progress made on the development of an integrated multistage fluidized bed retorting process (KENTORT II) during the period of October 1, 1992 through September 30, 1993 under Cooperative Agreement No. DE-FC21-90MC27286 with the Morgantown Energy Technology Center, US Department of Energy. 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 PDU was assembled, instrumented and tested during this fiscal year. Along with the major activity of commissioning the 50-lb/hr retort, work was also completed in other areas. Basic studies of the cracking and coking kinetics of model compounds in a fixed bed reactor were continued. Additionally, as part of the effort to investigate niche market applications for KENTORT II-derived products, a study of the synthesis of carbon fibers from the heavy fraction of KENTORT II shale oil was initiated.

This book was released on 1992 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1994 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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, 1994 through March 31, 1994 under Cooperative Agreement No. DE-FC21-90MC27286 with the Morgantown Energy Technology Center, U.S. Department of Energy. 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. Modifications to the system were completed that improved the start-up burner system and reduced thermal losses. Final shakedown tests were performed that demonstrated gasification zone and combustion zone temperatures of 800 and 900°C, respectively, at a raw shale feed rate of 50 lb/hr. Ash agglomeration and slagging was encountered during some of these tests, and these materials were analyzed by scanning electron microscopy and energy dispersive X-ray analysis. By limiting the combustion plenum chamber to 1100°C during heat up and by maintaining sufficient solid recycle to the combustor, it is believed that ash agglomeration difficulties will be eliminated.

Available in PDF, EPUB and Kindle. Book excerpt: The fluidized-bed reactor is the centerpiece of industrial fluidization processes. This book focuses on the design and operation of fluidized beds in many different industrial processes, emphasizing the rationale for choosing fluidized beds for each particular process. The book starts with a brief history of fluidization from its inception in the 1940’s. The authors present both the fluid dynamics of gas-solid fluidized beds and the extensive experimental studies of operating systems and they set them in the context of operating processes that use fluid-bed reactors. Chemical engineering students and postdocs as well as practicing engineers will find great interest in this book.
