METHOD FOR SELECTIVE HYDROGENATION USING A CATALYST CONTAINING IRON AND AT LEAST ONE METAL SELECTED FROM BETWEEN 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.

1. Method for selective hydrogenation of a hydrocarbon feedstock that contains at least 2 carbon atoms per molecule and that has a final boiling point that is less than or equal to 250° C. and that comprises at least one polyunsaturated compound, in which in the presence of hydrogen, said feedstock is brought into contact with at least one catalyst that comprises a substrate and an active metal phase that is deposited on said substrate; said active metal phase comprises iron and at least one metal that is selected from between zinc and copper in a molar ratio of Fe:(Zn and/or Cu) of between 0.35 and 0.99.
