Effects of Catalytic Activity and Solvent Composition on Two-Stage Coal Liquefaction Haru-umi Hasuo, Kinya Sakanishi,* Hideki Taniguchi, Masahiro Kishino, and Isao Mochida Institute of Advanced Material Study, Kyushu University, Kasuga, Fukuoka 816, Japan
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 (
