Catalytic activities of NiMo supported on hollow carbon black (Ketjen Black), a commercial NiMo/ alumina, and a synthetic pyrite were examined in the single- and two-stage liquefaction of Wyoming subbituminous and Yallourn brown coals with tetralin or 1-methylnaphthalene. The two-stage liquefaction consisting of lower temperatures (
