The present invention relates to a process for producing a metallic catalyst layer or coating which serves for effectuating the removal of hydrogen from a gas mixture containing hydrogen and oxygen. The catalyst layer itself which is porous, comprises a metal, such as palladium (Pd) or platinum (Pt), or alloys of these metals, which catalytically influence the oxidation of hydrogen. The metal or the metal alloy is applied as a catalyst layer or coating onto a carrier material or substrate by either plasma spraying or flame spraying. The present invention also provides a catalyst through the intermediary of a catalyst layer which is produced in accordance with the process of the instant invention.

Process for producing a catalyst layer on a carrier and a catalyst

A catalyst for the removal or elimination of hydrogen from an atmosphere containing hydrogen, oxygen and steam. The catalyst consists of a metal or a corresponding alloy which influences the oxidation of the hydrogen, and which is applied onto a substrate material as a catalyst layer. The catalyst layer is applied onto the substrate which is formed from plate or sheet metal, fabric, mesh or granulate and consists of a support material which will regard to its expansion under a temperature change is compatible with the catalyst layer and is corrosion-resistance of the substrate material prevents the oxidation thereof in the presence of steam.

Catalyst for the removal of hydrogen from an atmosphere containing

An arrangement for the avoidance of a deposition of a fatty substance, such as liquid lubricant or grease possessing high viscosity which is carried along with steam during a combustion of hydrogen from a gas mixture containing hydrogen, oxygen and steam, through the intermediary of catalytic igniters.

Arrangement with protective effectiveness against the deposition of

A catalytically acting system of metal layers for the removal or elimination of hydrogen from a gas mixture, which also contains hydrogen and oxygen. The system of metal layers possesses a surface layer which faces the gas mixture, and which is constituted of a PdNiCu alloy and which acts as a catalyst during the oxidation of the hydrogen. The surface layer is connected with or bonded to a carrier consisting of a heat-conductive material.
