Since coal conversion, in the presence of tetralin (a donor solvent), is believed to be a coal rank phenomenon, it seemed worthwhile to determine the role of rank upon conversion of tetralin (T) to naphthalene (N) during coal liquefactions at 385/degree/, 427/degree/ and 445/degree/C. The THF soluble fractions, containing T and N, were analyzed using a high performance liquid chromatographic technique. The T/N ratios, for eight coal samples of different ranks, showed a direct relationship between the coal rank and the T/N ratio. The conversion of tetralin to naphthalene was lowest for the highest rank coal, and vice versa. The T/N ratio versus rank relationship was obtained for reaction times ranging from 5 to 65 minutes.
