A process for preparing a catalyst comprising nickel and copper, comprising the following steps: impregnating the porous support with a volume of a butanol solution of between 0.2 and 0.8 times the total pore volume of the support; maturing the impregnated porous support for 0.5 to 40 hours; impregnating the matured impregnated support with a solution comprising a precursor of the nickel active phase; impregnating the support with a solution containing a copper precursor and a nickel precursor.

A process for preparing a catalyst comprising an active phase based on nickel and an alumina support, which process comprises the following steps: a) said support is impregnated with a volume V1 of a butanol solution of between 0.2 and 0.8 times the total pore volume TPV of said support in order to obtain an impregnated support; b) the impregnated support obtained at the end of step a) is left to mature for 0.5 to 40 hours; c) the matured impregnated support obtained at the end of step b) is impregnated with a solution comprising at least one precursor of the nickel active phase in order to obtain a catalyst precursor; d) the catalyst precursor obtained at the end of step c) is dried at a temperature below 250° C.
