The present invention is directed to a catalyzed metallic substrate, such as a metal plate. There is a catalyst layer supported on the substrate surface. The article is useful as part of exhaust systems which can be used with small engines for applications such as motorcycles, lawn mowers, chain saws, weed trimmers and the like. The present invention includes methods to prepare the catalyzed metal substrate and methods of use of the catalyzed substrate.

Catalytic metal plate

A layered catalyst member useful for catalytically generating a hydrogen-rich gas from a hydrocarbon feed. The layered catalyst member comprises a monolith substrate containing at least one layer of a steam reforming catalyst in contact with at least one layer of a catalytic partial oxidation catalyst. The steam reforming catalyst comprises one or more platinum group metal components and the catalytic partial oxidation catalyst comprises palladium components.

Process for generating hydrogen-rich gas

A process for catalytically generating a hydrogen-rich gas from a hydrocarbon feed. A stream comprising the hydrocarbon feed , water and air is preheated to a temperature sufficiently high to initiate catalytic partial oxidation of the hydrocarbon feed. The preheated stream is then introduced into an autothermal reactor containing a layered catalyst member at a temperature sufficient to initiate and sustain both catalytic partial oxidation and catalytic steam reforming. At least part of the hydrocarbon feed is catalytically partially oxidized to produce a hydrogen-rich gas comprising hydrogen and carbon oxides and hydrocarbons remaining in the feed are steam reformed to produce further quantities of the hydrogen-rich gas. The layered catalyst member comprises a monolith substrate containing at least one layer of a steam reforming catalyst in contact with at least one layer of a catalytic partial oxidation catalyst. The steam reforming catalyst comprises one or more platinum group metal components and the catalytic partial oxidation catalyst comprises palladium components.

This invention provides a novel rhodium-ruthenium catalyst composition which is adapted for highly selective conversion of synthesis gas to acetic acid and related oxygenated two-carbon hydrocarbon derivatives.
