Illinois coal/RDF coprocessing to produce high quality solids and liquids. (Quarterly) technical report, December 1, 1993--February 28, 1994

摘要

It is the aim of this study to provide information pertinent to the development of a coal/RDF pyrolysis process capable of economically creating valuable products from high sulfur Illinois coal. This project will be carried out in a systematic manner. First, samples will be properly selected prepared, preserved and characterized. Then coals, various plastics, cellulose, and a high quality RDF will be pyrolyzed, steam pyrolyzed, hydro-pyrolyzed, and liquefied at various conditions. Next, blends of coal with various RDF components will be reacted under the same conditions. From this work synergistic effects will be identified and process parametric studies will be conducted on the appropriate mixtures and single components. Product quality and mass balances will be obtained on systems showing promise. Preliminary pyrolysis work will be conducted on a TGA. Over 100 microreactor experiments have been performed and the acquisition of products for analysis has been achieved. Interactions occur between 400--450(degrees)C. The use of higher temperatures should be avoided if liquids are the.desired product. Although, these results are preliminary they are also very encouraging.
