Abstract
This invention relates to processes for catalytically oxidizing organic compounds (for example methane, ethane, propylene and carbon monoxide) catalytically reducing oxides of nitrogen with a reducing fuel and the production of methane by the steam reforming of naphtha and naphtha distillates. In particular the invention relates to a process for the oxidation of carbon monoxide or a hydrocarbon present in an oxygen-containing gas stream to carbon dioxide and water. In particular the invention relates to a process for the oxidation of carbon monoxide or a hydrocarbon present in an oxygen-containing gas stream to carbon dioxide and water, the process comprising passing the said gas stream at an elevated temperature through a supported catalyst consisting essentially of an inert material, an intermediate coating thereon containing at least one oxide selected from the group consisting of the oxides of scandium, yttrium and the lanthanides and a catalytically active surface coating on said intermediate coating of an alloy selected from the group consisting of (1) platinum/rhodium alloys wherein the rhodium constitutes 1-50 weight % of the total metal content of the alloy and the platinum the balance; and (2) platinum/rhodium/base metal alloys wherein the rhodium constitutes 1-50 weight % of the total metal content of the alloy, the base metal from 0.01 to 25 weight % of the said total metal content and the platinum the balance, the base metal being selected from the group consisting of aluminium, magnesium, bromium, molybdenum, tungsten, manganese, iron, cobalt, nickel, titanium, vanadium, thorium, uranium, copper, silver, zinc, cadmium, mercury, indium, thallium, bismuth, tin, lead, antimony, the lanthanides and the actinides.
