Abstract: Process for hydrogenation of aromatic compounds in a feedstock comprising hydrocarbons having at least five carbon atoms, comprising: a) contacting feedstock, a hydrogen gas, and a nickel or platinum hydrogenation catalyst at 100 to 400° C., 0.5 to 8 MPa, and a feedstock flow rate 0.5 to 5 h−1, as to produce a partially-hydrogenated hydrocarbon feedstock and gas; and b) contacting the partially-hydrogenated feedstock, and a nickel or platinum hydrogenation catalyst at 100 and 400° C., a pressure of between 0.5 and 8 MPa, with a flow rate of the partially-hydrogenated feedstock between 0.3 and 8 h−1, a ratio between the volume of hydrogen and the volume of the partially-hydrogenated feedstock between 0.3 and 3 Nm3/m3, and a ratio between the superficial mass flow rate of the partially-hydrogenated feedstock and the superficial mass flow rate of gas (Ul/Ug) at the inlet of the reactor between 50 and 500.
