    Abstract: The present invention relates to a specific packaged hydrogenation catalyst comprising a packaging and a hydrogenation catalyst, wherein the packaging comprises a specific polymer, and wherein the packaged hydrogenation catalyst has a specific weight ratio of the polymer to the hydrogenation catalyst enclosed in the packaging. The packaged hydrogenation catalyst has the advantage of a high catalyst to polymer weight ratio and that it is suitable for direct use in a hydrogenation reaction without the need of unpacking the hydrogenation catalyst from the packaging. Further, the present invention relates to a process for preparing said specific packaged hydrogenation catalyst, and a packaged hydrogenation catalyst obtained or obtainable by said process. In addition thereto, the present invention relates to a use of the packaged hydrogenation catalyst according to the present invention and a process for the hydrogenation of an unsaturated hydrocarbon feedstock.

    Abstract: Catalytic articles comprising a substrate having a catalytic coating thereon, the catalytic coating comprising a catalytic layer having a thickness and an inner surface proximate to the substrate and an outer surface distal to the substrate; where the catalytic layer comprises a noble metal component on support particles and where the concentration of the noble metal component towards the outer surface is greater than the concentration towards the inner surface are highly effective towards treating exhaust gas streams of internal combustion engines. The articles are prepared via a method comprising providing a first mixture comprising micron-scaled support particles and applying the first mixture to a substrate to form a micro-particle layer; providing a second mixture comprising nano-scaled support particles and a noble metal component having an initial pH and applying the second mixture to the micro-particle layer and calcining the substrate.
