A new active stable catalyst for use in the removal of sulphur, nitrogen, contaminating metals, asphaltenes and Conradson carbon from heavy crudes and residues and, in particular, a method for the preparation of the catalyst and a process for the treatment of heavy crudes and residues with the catalyst. The catalyst comprises a hydrogenation component selected from Group VIB of the Periodic Table, a hydrogenation component selected from Group VIII of the Periodic Table and a phosphorus oxide component as active components all supported on an alumina carrier. The catalyst is made up of a dispersion of the above metals on the surface of the alumina carrier such that, when the catalyst is sulphided under specific conditions, catalytic activities such as hydrodesulphurization (HDS), hydrodenitrogenation (HDN) and hydrodemetallization (HDM) and the conversion of asphaltenes and Conradson carbon are improved.
