摘要: A self-starting, self-sustaining hydrogen generator comprises a reactor packed with a mass of mixed catalyst, containing supported copper and palladium. A feedstock, of e.g. methanol and an oxygen source such as air, is injected at high velocity into the mass of catalyst through a multipoint entry such as a tube of porous ceramic. The mass of catalyst is preferably configured concentrically around the tube injector, so that the fluid-flow follows a radial path through the reactor. The product gas is high in hydrogen and can be used as a feed for a fuel cell.

摘要: A continuous process for the dehydrogenation of a hydrocarbon and/or oxygenated hydrocarbon feed, comprising contacting the hydrocarbon and/or oxygenated hydrocarbon feed with a dehydrogenation catalyst at elevated temperature in a reaction zone characterized in that the catalyst is capable of retaining hydrogen and (a) is contacted with a feed to form a dehydrogenated product and hydrogen, at least some of the hydrogen formed being adsorbed by the catalyst and/or reacting therewith to reduce at least part of the catalyst; (b) the dehydrogenated product and any unadsorbed/unreacted hydrogen is removed from the reaction zone; (c) at least some of the adsorbed hydrogen is removed from the catalyst and/or at least some of the reduced catalyst is oxidized; and (d) reusing the catalyst from step (c) in step (a).

摘要: A method for preparing a catalyst suitable for oxidation of carbon monoxide comprises the steps of treating a high surface area carbon support with an aqueous solution of a stannic salt and a promoter, drying, reacting with hydrazine hydrate in a hydrocarbon, washing and drying. The catalyst may be used in breathing apparatus.
