Abstract
In a catalyst process involving a conversion reaction for organic compounds, e.g. hydrogenations, the catalyst contains at least one support and at least one metal, and is characterized in that it has particles of an average size greater than approximately 1 nm, and more than 80% of particles, the size of which is comprised in the range D±(D.0.2) where D represents the average size of the particles. The catalyst is prepared in a colloidal suspension, in aqueous phase, of the metal oxide or metals to be supported, then depositing this suspension on a support, and optionally reducing the oxide thus supported.
