Abstract: The present invention relates to a structured packing element (21) having the shape of a rectangular flat plate, provided with slots (23) and recesses (22). The slots (23) are intended for assembly by interlocking the structured packing elements together in order to form the structured packing. The recesses (22) are provided in order to form channels within the structured packing.The present invention also relates to a packing structure obtained by assembling such packing elements (21), the use of such a packing for an operation of bringing a gas and a catalyst into contact, and a manufacturing process of such a structured packing.

Abstract: A method for treatment of a gas having 10 to 0.5% by volume of at least one of COS and CS2, and 30 ppm to 5% by volume of unsaturated hydrocarbons: a) hydrogenation of organic compounds unsaturated with respect to paraffins by contacting the gas with a hydrogenation catalyst in the presence of hydrogen at 100 to 400° C., to provide an effluent that is low in unsaturated hydrocarbon compounds, the hydrogenation catalyst having at least one metal that is palladium, platinum, nickel, or cobalt deposited on a porous substrate. b) catalytic hydrolysis-hydrogenation in the presence of water of COS and/or CS2 present in the effluent of a) to provide an H2S-rich effluent by bringing the effluent from a) into contact with a hydrolysis-hydrogenation catalyst.
