PROCESS FOR THE PREPARATION OF A BIMETALLIC CATALYST BASED ON NICKEL AND PLATINUM OR PALLADIUM

摘要

A process for the preparation of a catalyst comprising a bimetallic active phase based on nickel and platinum or palladium, and a support comprising a refractory oxide comprising the following steps: a) a step is taken to bring the support into contact with a solution containing a nickel precursor; b) performing a step of contacting the support with a solution containing a platinum or palladium precursor; the steps a) and b) being performed separately in an indifferent order; c) a step of drying the catalyst precursor at the end of step a) and b), or b) and a), at a temperature below 250 ° C; d) supplying the catalyst precursor obtained at the end of step c), in a hydrogenation reactor, and carrying out a reduction step by bringing said precursor into contact with a reducing gas at a temperature of between 210.degree. and 280 ° C between 5 minutes and 40 hours.
