ABSTRACT A method of hydrogen treatment of coal tar or coal tar pitch having high asphaltene content and a high aromaticity, characterized in that the hydrogen treatment is carried out at a hydrogen pressure of from 3.92 to 17.64 MPa (40-180 kg/m2G), a temperature of from 300 to 420°C and a liquid hourly space velocity of from 0.2 to 2 hr-1 using a catalyst comprising a first catalytic component containing Mo and a second catalytic component containing Ni and/or Co carried on a substrate. The respective metal oxide contents of the first and second catalytic components in the catalyst being from 10 to 30 weight percent and from 1 to 6 weight percent. The catalyst having pores with a pore diameter of more than 3.5 nm and with the following physical properties: (a) an average pore diameter (APD) of from 9.8 to 15.4 nm; (b) a total pore volume (PV) of from 0.450 to 0.632 cc/g; (c) a surface area (SA) of from 137 to 215 m2/g; (d) a pore size distribution as follows: pore diameter (nm) specific volume (cc/g) 3.5 - 5 less than 0.1 5 - 8 less than 0.3 8 - 18 0.2 - 0.55 18 - 30 less than 0.2 over 30 less than 0.1; and (e) the ratio of the volume of pores with diameters of 8-18 nm to the total pore volume PV being 0.758-0.911.
