SELECTIVE HYDROGENATION METHOD USING A CATALYST CONTAINING IRON AND AT LEAST ONE METAL SELECTED FROM ZINC OR COPPER

摘要

The invention concerns a method for selectively hydrogenating a hydrocarbon charge containing at least two carbon atoms per molecule, having a final boiling point which is less than or equal to 250°C, and comprising at least one polyunsaturated compound, wherein the charge, in the presence of hydrogen, is brought into contact with at least one catalyst comprising a carrier and an active metal phase deposited on the carrier, the active metal phase comprising iron and at least one metal selected from zinc and copper in a molar ratio of Fe : (Zn and/or Cu) of between 0.35 and 0.99.
