Graphic values for some organic constitutents of beneficiated coal samples

PDF Version Also Available for Download.

Description

Graphic techniques exist which can accurately predict values for calorific value, organic sulfur, and possibly other constituents of the organic portion of beneficiated coal sample fractions. These techniques also permit a determination of coal rank to be made without the use of the approximations required in the standard procedure. Fractions of IBC-101 with varying ash contents were produced by froth flotation. The various fractions were analyzed by the coal analysis laboratory and the particular data type was plotted in each case vs. the individual ash content of each fraction, using Lotus 123 and Freelace software packages. Such plots for calorific ... continued below

Graphic techniques exist which can accurately predict values for calorific value, organic sulfur, and possibly other constituents of the organic portion of beneficiated coal sample fractions. These techniques also permit a determination of coal rank to be made without the use of the approximations required in the standard procedure. Fractions of IBC-101 with varying ash contents were produced by froth flotation. The various fractions were analyzed by the coal analysis laboratory and the particular data type was plotted in each case vs. the individual ash content of each fraction, using Lotus 123 and Freelace software packages. Such plots for calorific value and organic sulfur have, so far, been made. These curves and the information they contain are discussed in this report. A comparison of the graphic mineral matter value with the usual one calculated from the Parr approximation has been made. Eventually, the data may lead to an effective way to estimate inorganic carbon, hydrogen, nitrogen, and other organic constitents of coal. All data will be made available to researchers.
