PROCESS FOR THE PREPARATION OF A BIMETALLIC CATALYST BASED ON NICKEL AND COPPER FOR THE HYDROGENATION OF AROMATIC COMPOUNDS

摘要

A process for the preparation of a catalyst comprising a bimetallic active phase based on nickel and copper, and a support comprising a refractory oxide comprising the following steps: a step is taken to bring the support into contact with a solution containing a precursor of nickel; a step is taken to bring the support into contact with a solution containing a copper precursor; a step is taken to dry the catalyst precursor at a temperature below 250 ° C .; the catalyst precursor obtained is supplied in a hydrogenation reactor and a reduction step is carried out by contacting said precursor with a reducing gas at a temperature of less than 200 ° C. for a period greater than or equal to 5 minutes and less 2 hours.
