ABSTRACT OF THE INVENTION A hydrotreating catalyst which is resistant to carbonaceous deposits and is particularly useful for hydrotreating coal-derived liquids, is molybdenum or tungsten disulphide in an amount of 0.1 to 10% by weight, substantially completely on the outer surface of an active carbon support having a surface ares in excess of 800 m2/g. The catalyst can be made by absorbing molybdenum or tungsten tri- sulphide onto the active carbon support and reducing the trisulphide to the disulphide.
