Process for the selective hydrogenation of polyunsaturated compounds containing at least 2 carbon atoms per molecule, contained in a hydrocarbon feed having a final boiling point less than or equal to 300 ° C in the presence of a catalyst comprising an alumina support and an active phase consisting of nickel, said catalyst being prepared by a process comprising at least: i) a step of contacting said support with at least one solution containing at least one nickel precursor; ii) a step of bringing said support into contact with at least one solution containing at least one organic compound comprising at least one amine function corresponding to the empirical formula CxNyHz in which x is between 1 and 20, y = 1-x and z = 2-2x + 2, or an amide function or an amino acid; iii) a step of drying said impregnated support at a temperature below 250 ° C; steps i) and ii) being performed separately, in any order, or simultaneously. |
