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. The majority of reactions will be conducted in microautoclaves. If this research is successful, a new market for high sulfur, high mineral Illinois coal would emerge. Samples needed for this project have been obtained and sample preparation have been completed. A Perkin Elmer TGA-7 was employed to study pyrolysis. significant interactions have been observed. About 200 microreactor experiments have been performed and the acquisition of products for analysis has been achieved. Interactions occur between 400-450{degrees}C. Synergism occurs at short reaction time. High temperature and long reaction times result in higher residue yields and a loss of synergisms. Reactive species may be required to stabilize intermediate products.
