This book was released on 1995 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The object of this grant is to test, analyze, and improve the heat and coal-slag corrosion resistance of a SIC(p)/AI203 ceramic composite tubular material. The material will be evaluated for its ability to withstand the pressures, temperatures and corrosion attack which would be encountered within a coal-fired high-temperature, high pressure air heater. The evaluation will include strength testing at elevated temperatures. The feasibility of several joining and coating techniques will also be investigated. Results from the following tasks and subtasks are presented: Task 1--materials; Task 2--pre and post test material characterization; Subtask 2A--strength of materials testing and analysis; Subtask 2B--corrosion thermodynamic analysis; Subtask 3A--bench scale lab tests; Subtask 3B--field exposure tests; and Task 4--project management. An appendix explains the coating of Lanxide SiC/Al2O3 ceramic composite.

Book Synopsis High Conversion of Coal to Transportation Fuels for the Future with Low HC Gas Production. Progress Report Number 10, January 1--March 31, 1995 by :
Download or read book High Conversion of Coal to Transportation Fuels for the Future with Low HC Gas Production. Progress Report Number 10, January 1--March 31, 1995 written by and published by . This book was released on 1995 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: An objective of the Department of Energy in funding research in coal liquefaction, is to produce a synthetic crude from coal at a cost lower than $30.00 per barrel (Task A). A second objective is to produce a fuel which is low in aromatics, yet of sufficiently high octane number for use in the gasoline-burning transportation vehicles of today. To meet this second objective, research was proposed for conversion of the highly-aromatic liquid product from coal conversion to a product high in isoparaffins, which compounds in the gasoline range exhibit a high octane number (Task B). Experimental coal liquefaction studies conducted in a batch microreactor have demonstrated potential for high conversions of coal to liquids with low yields of hydrocarbon (HC) gases, hence small consumption of hydrogen in the primary liquefaction step. Ratios of liquids/HC gases as high as 30/1, at liquid yields as high as 82% of the coal by weight, have been achieved. The principal objective of this work is to examine how nearly one may approach these results in a continuous-flow system, at a size sufficient to evaluate the process concept for production of transportation fuels from coal. A continuous-flow reactor system is to be designed, constructed and operated. The system is to be computer-operated for process control and data logging, and is to be fully instrumented. The primary liquid products will be characterized by GC, FTIR, and GC/MS, to determine the types and quantities of the principal components produced under conditions of high liquids production with high ratios of liquids/HC gases. From these analyses, together with GC analyses of the HC gases, hydrogen consumption for the conversion to primary liquids will be calculated. Conversion of the aromatics of this liquid product to isoparaffins will be investigated. Results to date on both tasks are presented.

This book was released on 1996 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the research conducted at the University of Tennessee Space Institute on high performance materials for use in corrosive environments. The work was supported by a US Department of Energy University Coal Research grant. Particular attention was given to the silicon carbide particulate reinforced alumina matrix ceramic composite manufactured by Lanxide Corporation as a potential tubular component in a coal-fired recuperative high-temperature air heater. Extensive testing was performed to determine the high temperature corrosion effects on the strength of the material. A computer modeling of the corrosion process was attempted but the problem proved to be too complex and was not successful. To simplify the situation, a computer model was successfully produced showing the corrosion thermodynamics involved on a monolithic ceramic under the High Performance Power System (HIPPS) conditions (see Appendix A). To seal the material surface and thus protect the silicon carbide particulate from corrosive attack, a dense non porous alumina coating was applied to the material surface. The coating was induced by a defocused carbon dioxide laser beam. High temperature corrosion and strength tests proved the effectiveness of the coating. The carbon dioxide laser was also used to successfully join two pieces of the Lanxide material, however, resources did not allow for the testing of the resulting joint.

This book was released on 1994 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: An announced objective of the Department of Energy in funding this work, and other current research in coal liquefaction, is to produce a synthetic crude from coal at a cost lower than $30.00 per barrel (Task A). A second objective, reflecting a recent change in direction in the synthetic fuels effort of DOE, is to produce a fuel which is low in aromatics, yet of sufficiently high octane number for use in the gasolineburning transportation vehicles of today. To meet this second objective, research was proposed, and funding awarded, for conversion of the highly-aromatic liquid product from coal conversion to a product high in isoparaffins, which compounds in the gasoline range exhibit a high octane number (Task B). Experimental coal liquefaction studies conducted in a batch microreactor in our laboratory have demonstrated potential for high conversions of coal to liquids with low yields of hydrocarbon (HC) gases, hence small consumption of hydrogen in the primary liquefaction step. Ratios of liquids/HC gases as high as 30/1, at liquid yields as high as 82% of the coal by weight, have been achieved. The principal objective of this work is to examine how nearly we may approach these results in a continuous-flow system, at a size sufficient to evaluate the process concept for production of transportation fuels from coal. Accomplishments to date are reported.

This book was released on 1981 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This program is to evaluate the erosion-, abrasion- and galling-resistance of valve materials and materials processing methods for improved wear in coal conversion and utilization components. The research is organized into four tasks: erosion testing of potential valve materials at several particle velocities and impingement angles, support to Morgantown Energy Technology Center (METC) valve development program, liaison and consultation to DOE contractors on materials for wear resistance, and testing of laser-processed valve seats in coal ash. Erosion studies on potential valve materials were halted during the first quarter to allow overhaul of the erosion apparatus and change to a larger nozzle (1.5 mm I.D.). Changeover from minus 27 .mu.m Al/sub 2/O/sub 3/ particles to minus 50 .mu.m Al/sub 2/O/sub 3/ was also made. These changes will allow better comparison of erosion data with other laboratories.

Book excerpt: "The subcommittee has called this hearing so that members might learn more about coal ash, the small businesses that turn coal ash into useful products and the concerns that these businesses have about the proposed Federal regulations that they believe may have a negative effect on their industry ... The EPA has recently issued two proposals for regulating coal ash. One would regulate coal ash as a solid waste and would provide very limited Federal enforceability and may not provide adequate protection of the environment and human health. The other would list coal ash as a special waste under the Hazardous Waste Subtitle in the Resource Conservation and Recovery Act, Subtitle C. The second option is one that we will focus on ... since it has generated great concerns among small businesses across this country. These businesses, many of which are represented here today, have reason to believe that regulating coal ash under Subtitle C, even as a special waste, will open recycling operations to added litigation and a stigma that will discourage the ... use of the products made with recycled coal ash."--P. 1-2.
