Abstract

The influence of solvent was examined in the single- and two-stage

liquefaction of Tanito Harum coal with FeNi supported oil carbon black

(FeNi/KB) and a synthetic pyrite. FeNi/KB catalyst provide a high oi l yield in

the single-stage liquefaction when tetralin or 1methylnapthalene was

used, while pyrite (FeS2) gave a low oil yield in the liquefaction with 1-

methylnapthalene although it produced a high enough oil yield in the

liquefaction with tetralin. The single-stake liquefaction of coal gave extremely

low oil yields under the solvent free conditions for all catalysts examined. In

the liquefaction of coal with solvent, the difference of oil yield produced

between single-stage and two stage is small. However, the conversion of H--

donor solvent after liquefaction was much lower than that of single-stage

liquefaction. In the free-solvent liquefaction coal, two-stage liquefaction

produced much higher oil yield than single-stage.
