This book was released on 1986 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This technical note (TN) reports on the development of a zero-order ASPEN (Advanced System for Process Engineering) model for the fluidized-bed retort/combustion of an eastern oil shale. The objective of the work described was to identify data needs and to create a structure for future, more definitive models. New Albany shale was the initial reference eastern shale at the Department of Energy (DOE)/Morgantown Energy Technology Center (METC). A literature search on this shale was conducted to find the physical property data required for the ASPEN model. This TN discusses the types of missing or incomplete data, the process being modeled, and how process variables are affected by varying input parameters. The TN also presents recommendations for increasing the reliability of the simulation. 12 refs., 3 figs., 5 tabs.

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.

This book was released on 2012-12-06 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: Oil shales are broadly dermed as petroleum source rocks containing sufficiently high contents of organic matter (above ca 10-15 wt. %) to make utilisation a possibility. Like coal, the world's reserves of oil shales are vast being many times larger than those proven for crude oil. Indeed, some of the largest deposits occur in the USA and Europe where Estonia and Turkey have large reserves. The first recorded interest in oil shale retorting was an English patent in 1694 (Eele, Hancock and Porter, No. 330) which refers to distilling noyle from some kind of stone". The oil shale retorting industry dates back to the middle of the last century, notably Scotland, Estonia, France and Sweden in Europe. Indeed, my own Department at the University of Strathclyde has a historical link with James "Paraffin" Young, the founder of the Scottish oil shale industry who endowed a chair in Applied Chemistry. The growth of the oil industry saw the demise of the oil shale industry in most countries with the notable exception of Estonia, where kukersite has continued to be used for power generation and retorting. However, oil shale utilisation has attracted renewed attention since the early 1970s as a source of transport fuels and chemical feedstocks due to the the long term uncertainties over crude oil supplies.

This book was released on 1995 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: This summarizes the development of the KENTORT II retorting process, which includes integral fluidized bed zones for pyrolysis, gasification, and combustion of oil shale. Purpose was to design and test the process at the 50-lb/hr scale. The program included bench- scale studies of coking and cracking reactions of shale oil vapors over processed shale particles to address issues of scaleup associated with solid-recycle retorting. The bench-scale studies showed that higher amounts of carbon coverage reduce the rate of subsequent carbon deposition by shale oil vapors onto processed shale particles; however carbon-covered materials were also active in terms of cracking and coking. Main focus was the 50-lb/hr KENTORT II PDU. Cold-flow modeling and shakedown were done before the PDU was made ready for operation. Seven mass-balanced, steady-state runs were completed within the window of design operating conditions. Goals were achieved: shale feedrate, run duration (10 hr), shale recirculation rates (4:1 to pyrolyzer and 10:1 to combustor), bed temperatures (pyrolyzer 530°C, gasifier 750°C, combustor 830°C), and general operating stability. Highest oil yields (up to 109% of Fischer assay) were achieved for runs lasting ≥ 10 hours. High C content of the solids used for heat transfer to the pyrolysis zone contributed to the enhanced oil yield achieved.

This book was released on 1994 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now well accepted that fluidized bed pyrolysis of oil shale at near-zero hydrogen partial pressure will generate higher than Fischer assay oil yields. This enhancement varies according to shale type, but for most shales, it can be significant. It has been shown that fluidized bed pyrolysis of eastern and western US oil shales can enhance oil yields by 50% and 10% above Fischer assay, respectively. In addition, fluidized bed technology offers the advantages of rapid pyrolysis kinetics (short solid residence time), total use of mined shale, and thermal efficiency. The Center for Applied Energy Research (CAER) has developed a commercial retorting concept, KENTORT 2, which is based on fluidized bed technology. This process has been successfully demonstrated in a 3-inch diameter, 5-lb/hr system at the CAER using eastern US oil shale. This report summarizes the progress made on the development of an integrated multistage fluidized bed retorting process during the period of October 1, 1993 through December 31, 1993. The KENTORT 2 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 2 process at the 50-lb/hr scale. Retort shake-down tests were performed this quarter, and during one of these tests, oil was generated for the first time in the 50-lb/hr system. Minor equipment problems were also identified and a remediation plan was implemented.
