Abstract:
1. A process for the preparation of a catalyst comprising at least one metal M1 and a promoter M2 on a substrate, said process comprising: a) preparing a colloidal oxide suspension of a first metal M1 by neutralization of a basic solution by an acidic mineral solution that contains a precursor of the metal M1, b) contacting a precursor of the promoter M2, either directly in crystallized form or after dissolution in aqueous phase, with the colloidal suspension obtained in a), c) contacting a colloidal suspension obtained in b) with the substrate, and d) drying at a temperature of between 30° C. and 200° C., under a flow of air, wherein promoter M2 is an element selected from groups 11, 13 or 14 of the periodic table.
