A process for treating a charge hydrocarbon feed containing undesired aromatics, sulphur and nitrogen comprises: maintaining a sulphided catalyst bed comprising 0.1-15% by weight of one or more Group VIII metals selected from nickel, cobalt and iron; from 1-50% by weight of tungsten and/or from 1-20% by weight of molybdenum or chromium, and 0.01-10% by weight of zinc, on an activated carbon support, said support having a B.E.T. surface area of at least 600 m<2>/g, a pore volume of at least 0.3 cm<3>/g and an average pore diameter of at least 12 Angstroms; passing a charge hydrocarbon feed in the presence of a gas comprising greater than 60% by volume pure hydrogen into contact with said catalyst under hydrotreating conditions, thereby effecting hydrogenation, hydrodearomatisation, hydrodesulphurisation and hydrodenitrogenation of said feed and forming a hydrocarbon product stream containing a lesser concentration of undesired aromatics, sulphur and nitrogen, and recovering said product stream. cha |
