Abstract
A process for the substantial removal of at least one of the carbon monoxide and hydrogen impurities contained in a composite gas, according to which: (a) at least one of the carbon monoxide and hydrogen impurities contained in the composite gas are reacted with oxygen, in contact with a catalyst comprising particles of at least one metal chosen from the group consisting of gold and palladium, these particles being supported by titanium dioxide, in order respectively to form carbon dioxide and water; (b) optionally, the carbon dioxide and the water formed are removed from the composite gas; (c) the composite gas, substantially free of its carbon monoxide and/or hydrogen impurities, is recovered.
