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 of 300 ° C or lower, which process is carried out at a temperature of between 0 and 300 ° C., at a pressure of between 0.1 and 10 MPa, at a molar ratio of hydrogen / (polyunsaturated compounds to be hydrogenated) of between 0.1 and 10 and at an hourly space velocity of between 0.1 and 200 h. 1 when the process is carried out in the liquid phase, or at a molar ratio of hydrogen / (polyunsaturated compounds to be hydrogenated) of between 0.5 and 1000 and at an hourly volume rate of between 100 and 40,000 h -1 when the process is carried out in phase gas, in the presence of a catalyst comprising an active phase comprising nickel, and a support comprising an amorphous mesoporous alumina having a connectivity (Z) greater than 2.7. |
