Abstract: 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 together with a jet of an inert gas. 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.

Abstract: 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.

Abstract: 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.

Abstract: A device for recombination of hydrogen and oxygen with the aid of a catalyst system comprises the catalyst system in a housing 1, which has at least one inlet opening and at least one outlet opening, which are sealed by means of first seals 7 which open as a function of temperature. In this housing, a gas-permeable filter system is also provided in such a manner that after opening of the first seals, the gases or gas mixtures entering the inlet opening do not reach the catlayst system until they have first passed through the filter system. The filter system is essentially impermeable to aerosols and grease.

Abstract: An apparatus for removing hydrogen from a mixture of gases containing hydrogen, oxygen, steam, and aerosols, with a catalyst arrangement composed of a substrate coated with a material which catalyzes the oxidation of hydrogen while releasing heat. The apparatus is characterized by a protective device which encloses a catalyst arrangement until a preset temperature is reached. Once the preset temperature is reached, the apparatus is automatically movable into a position which exposes the catalyst arrangement, with the protective device being permeable to gas pressure but essentially impermeable to aerosols. Consequently, the catalyst arrangement is protected against deposition of aerosols contained in the gas mixture until the preset temperature is reached.

Abstract: 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.
