Proximate and ultimate analyses, heat-of-combustion, forms-of-sulfur, free-swelling index, and ash-fusion-temperature determinations for 29 Pennsylvanian coal samples from southeastern Kansas. For each sample number, the analyses are reported three ways: first, as-received; second, moisture-free; and third, moisture and ash free. All analyses by Coal Analysis Section, U.S. Department of Energy, Pittsburgh, Pennsylvania. Kcal/kg = 0.556 (Btu/lb); °F = (°C x 1.8) + 32. (*D176055 is a composite of samples D176055 and D176056; D176046 of samples D176046 and D176047; D183112 of samples D183112 and D183113; D176048 of samples D176048 and D176049; D176050 of samples D176050, D176051, and D176052; and D176053 of samples D176053 and D176054.)

Major- and minor-oxide and trace-element composition of the laboratory ash of 36 Pennsylvanian coal samples from southeastern Kansas. Coal ashed at 525°C. S following element (e.g., Ag-S) indicates determinations by semiquantitative emission spectrography. (The spectrographic results are to be identified with geometric brackets whose boundaries are part of the ascending series 0.12, 0.18, 0.26, 0.38, 0.56, 0.83, 1.2, etc., but reported as midpoints of the brackets 0.1, 0.15, 0.2, 0.3, 0.5, 0.7, 1.0, etc. Precision of the spectrographic data is plus-or-minus one bracket at 68% or plus-or-minus two brackets at 95% confidence level.) L = less than the value shown; N = not detected; B = not determined.

Major-, minor-, and trace-element composition of 36 Pennsylvanian coal samples from southeastern Kansas (whole coal basis). As, F, Hg, Sb, Se, Th, and U values are from direct determinations on air-dried (32° C) coal; all other values were calculated from analyses of coal ash. S following element (Ag-S) indicates analysis by emission spectrography. L = less than the value shown; N = not detected; B = not determined; * = tipple sample.
