Distribution of inorganics in low-rank coals

OSTI ID:5593036
Chemical characterization of vertical sequences of low-rank coals has been completed for the Beulah-Zap and Kinneman Creek Beds in North Dakota and initiated for the Yampa subbituminous coal (Colorado) and the Martin Lake lignite (Texas). Results show significant vertical variation patterns within seams. Chemical fractionation and carboxylic-acid-group-determination studies of twenty low-rank coals have been completed including a comparison of high-Na and low-Na types from the Beulah and Gascoyne, ND, seams. Chemical fractionation results aid in recognition of element affinities to organic and inorganic coal components. Form and composition of minerals in the Beulah-Zap lignite and Yampa subbituminous coal have been determined using scanning electron microscope and microprobe (SEM/EMPA) procedures. Quantitative analysis of the chemistry of coal components has been initiated by SEM/EMPA with study of organically-bound elements in the lithotypes and macerals of the Beulah-Zap, Hagel, and Martin Lake lignites and the Rosebud subbituminous coal. 3 figs., 5 tabs.
