Characterization of Alaskan coals: evaluation of their liquefaction behavior. Quarterly technical progress report, November 1984-January 1985

Accomplishments during this past quarter included characterization of the coals in the sample set and the running of liquefaction experiments using tetralin as a donor solvent. Analyses conducted included: ultimate and proximate analyses, calorific value determinations, vitrinite reflectance measurements and maceral composition evaluation. Preliminary results from the liquefaction runs indicate that the subbituminous C coals from the Beluga and Nenana coal fields are more readily converted to THF soluble products than the higher rank coals from the Matanuska and Northern Alaska coal fields. 2 refs., 4 tabs.
