This invention provides a method for hydrogenating coal tar. The method comprises: (1) filtering coal tar to remove solid particles with sizes larger than 25 mum; (2) dehydrating to prevent water from damaging the hydrogenation catalyst; (3) dedusting to remove solid particles with sizes smaller than 25 mum; (4) catalytically hydrogenating in a hydrogenation device to obtain gas-phase and liquid-phase products; (5) sending the liquid-phase products into a fractionation column, and fractionating to obtain gasoline, diesel oil and trail oil fractions. The method can realize all fractions hydrogenation of coal tar. |
