A long-term program is currently underway to determine the process response properties of pure single coal maceral fractions in order to predict the behavior of various whole coals of different maceral compositions and rank. The primary objectives of the study are to: (1) evaluate the reactivity of whole coals and macerals from other seams, covering the same broad rank range studied in the first phase of the program; (2) assess the degree of applicability of predictive equations for coals in general; and (3) evaluate the combustion characteristics of clean coals. This year, Argonne Premium samples were examined, as well as a number of coals obtained from various points throughout the US and the world (SIU coals). The coals were examined to determine if the relationships developed last year could be extrapolated to a wider rank range and maceral composition than the Hartshorne coals used in the last year's study. Efforts continued on modeling of the data obtained last year. Three cleaned and feed samples were obtained from OTISCA, Inc. Also, three feed and cleaned coals were obtained from the Pittsburgh Energy Technology Center and prepared. These coals will also be tested in the coming year's test matrix. A series of supercritical extraction (SCE) products, as well as the feeds, have also been tested. These samples were used to examine the effect of thermal desulfurization processing on combustion properties. A set of 50 samples has been obtained from the Pennsylvania State University. Twenty-five of these samples are of a rank series from the Lower Kittaning seam and will be used to further test and develop previously defined relationships. A second series is a set of high-sulfur coals. 20 refs., 2 figs., 3 tabs.
