Process for the preparation of a catalyst comprising an inert carrier, a larger quantity of cobalt and smaller quantities of scandium, characterized in that it comprises the following steps: 1) production of a first catalytic precursor (A) containing cobalt and at least part of the inert carrier, by the deposition of cobalt on the inert carrier; subsequent calcination, reduction and passivation of the inert carrier containing cobalt; 2) production of the final catalyst by the deposition of scandium on the catalytic precursor (A); subsequent calcination, reduction and passivation of the inert carrier containing cobalt and scandium. |
