Abstract
Process for the preparation of a catalyst including an inert support, cobalt, ruthenium and a third element selected from scandium and yttrium, comprising at least the following steps: 1) Preparation of a first catalytic precursor (A) containing cobalt and the inert support: subsequent calcination, reduction and passivation; 2) Preparation of a second catalytic precursor (B) containing cobalt, ruthenium and the inert support, by means of the deposition of ruthenium on the first catalytic support (A): subsequent calcination, reduction and passivation 3) Preparation of the final catalyst by means of the deposition of an element selected from scandium and yttrium on the catalytic precursor (B); subsequent calcination, reduction and passivation.
