Catalytic activity of NiMo supported on hollow carbon black was examined in the liquefaction of Wyoming subbituminus and Yallourn brown coals by pretreatment and the successive two stages at different temperatures. The oil yield in the liquefaction of Wyoming and Yallourn coals at 380℃-120min/440℃-60min provided 67wt% and 68wt%, respectively. The hydrogenation at a lower temperature appears to accelerate the conversion of asphaltene to oil by the successive stage of higher temperature.
