Zusammenfassung:	PURPOSE:To maintain the catalytic activity for a long period by depositing a specified amt. of Mo as a catalystic component and a specified amt. of one or both of Ni and Co on a carrier of a porous inorg. oxide consisting essentially of alumina. CONSTITUTION:A porous inorg. oxide carrier, consisting essentially of alumina or silica and alumina, having 80-180 Angstrom means pore diameter, whose pore diameter range and its volume ratio are shown in Table I, and having >=100m /g total surface area of the pore is formed. On said carrier, 10-30wt% Mo, expressed in terms of oxide, as the first catalytic component and 1-6wt% one or both of Ni and Co as the second catalytic component are deposited to obtain a hydrogenation catalyst of coal tar. Coal tar is hydrogenated at 40-180kg/cm G hydrogen pressure, at 300-420 deg.C, and at 0.2-2.0hr LHSV by using said catalyst.
