Spectroscopic characterization of Argonne Premium Coals and short residence time liquefaction products
Illinois No. 6 (high volatile bituminous), Pittsburgh No. 8 (bituminous), Wyoming Subbituminous, Pennsylvania Upper Freeport (medium volatile bituminous) and Pocahontas 3 (low volatile bituminous) coals from the Argonne Premium Coal Sample Program were heated in tetralin for 10 minutes at 430 /plus minus/5/degree/C. The products were examined by gel permeation chromatography and /sup 13/C NMR spectroscopy. Yields for conversion of the coals to THF-soluble products were determined. Yields and GPC characteristics of products from direct extraction of the coals with THF were determined. The most reactive coal in this group, based on conversion to products below MW 600, appears to be Wyoming subbituminous.
