“…No good correlation between the amounts of basic fractions, and Yallourn, Taiheiyo coal conversions was observed. It is well-known that tetrahydroquinoline is a hydrogen donor and good physical solvent for coal liquefaction (Guin et al, 1983; Panvelker et al, 1984;Hellgeth and Taylor, 1984). Such basic compounds were reported to be more effective liquefaction solvents than acidic and neutral compounds (Spencer, 1982).…”

To estimate a solvent ability for coal liquefaction, 26 kinds of anthracene oils with widely ranging characteristics were used for Yallourn and Taiheiyo coal liquefactions. Hydrogen contents of solvents were correlated well with Yallourn coal conversion having a large coefficient of correlation (0.90), whereas less value was obtained for Taiheiyo coal (0.81). The hydrogen donating ability (HDA) defined by the amount of dihydroanthracene produced in the reaction of the solvent with anthracene was correlated well with conversion to TS for both coals (coefficients of correlation were 0.90 and 0.94). Their relationship was applied to recycle solvents; however, smaller conversions than predicted by the regression curve were obtained. Removing n-paraffin from the recycle solvents increased coal conversion. It was considered that coal liquefaction.
