The overall objectives for this one-year project are: (1) to demonstrate that new fuels derived from Illinois high sulfur coal, namely (a) coal-sorbent pellets and (b) coal-water slurry produced from froth flotation feed can be effectively utilized in a circulating fluidized bed combustor, (2) to compare the carbon conversion efficiencies, SO2 and NO(subscript x) emission levels and Ca/S ratios needed to meet EPA regulations from the above fuels with those measured under similar operating conditions with a standard IBCSP coal, and (3) to analyze ash and spent limestone residues with a view to proposing waste disposal strategies for the combustion residues resulting from these new fuel forms.

There are applications where the combined combustion of coal and natural gas offers potential advantages over the use of either coal or natural gas alone. For example, low volatile coals or low volatile chars derived from treatment or gasification processes can be of limited use during to their poor flammability characteristics. However, the use of natural gas in conjunction with the solid fuel can provide the necessary ''volatiles'' to enhance the combustion. In addition, natural gas provides a clean fuel source of fuel which, in cofiring situations, can extend the usefulness of coals with high sulfur content. The addition of natural gas may reduce SO(subscript x) emission through increased sulfur retention in the ash and reduce NO(subscript x) emissions by varying local stoichiometry and temperature levels. In this research program, studies of combined coal and natural gas combustion will provide particle ignition, burnout rates and ash characterization, that will help clarify the effect of coal and natural gas and identify the controlling parameters and mechanisms.

Laboratory-scale research conducted at Southern Illinois University at Carbondale (SIUC) has shown that coal pyrolysis in the presence of CH4 and small quantities of O2 (the METHOXYCOAL process) can produce high yields of liquids and valuable chemicals compared to conventional pyrolysis. The addition of MgO, coal ash, and clays have been shown to further enhance coal conversion. The goal of this two-year project is to build upon that laboratory research by conducting continuous bench-scale tests at IGT. Tests are being conducted with IBC-101 coal under CH4/O2 blends with and without added coal ash, MgO, and/or clays, at temperatures and pressures up to 1000°F and 200 psig. These tests will provide data to select preferred operating conditions for chemicals production from high-sulfur Illinois coals.

Excerpt from Fuel Tests With Illinois Coal: Compiled From Tests Made by the Technologic Branch of the United States Geological Survey, at the St. Louis Fuel Testing Plant, 1904 June 30, 1907 The United States Geological Survey Technologic Branch has conducted at the St. Louis, Missouri, fuel testing plant, a series of investigations on the fuels of the United States. These tests included a large number of Illinois coals. The results of the tests have been published from time to time in a series of govern ment bulletins which contain very full descriptions of methods and very complete details of the results obtained. A complete list of the government bulletins is given at the end of this publi cation. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
