ABSTRACT:
Disclosed is a catalyst for hydrotreating a coal liquefaction and circulation solvent, in which .gamma.-alumina carrier carries at least one metal of Group VI of the Periodic Table in an amount of from 15 to 15% by weight as the oxide thereof and at least one metal of Group VIII of the same Table in an amount of from 3 to 10% by weight as the oxide thereof and the pore distribution as measured by mercury pressure porosimetry satisfies the conditions that the pores having a diameter of from 40 to 600 .ANG. have a mean diameter of from 9 to 150 .ANG. and the capacty of the pores having a diameter falling within the range of the mean diametr plus/minus 10 .ANG. is 65% or more of the capacity of the pores having a diameter of from 40 to 600 .ANG.. The catalyst is highly active for both hydrogenation and denitrogenation of coal-liquefying solvents.
