摘要
This invention relates to the purification of air and other gaseous media. In particular the invention is concerned with the decomposition of one or more of the oxides of nitrogen which may be present in a gas stream also containing gaseous compounds such as carbon monoxide and hydrocarbons. In certain cases, the gas stream may contain a stoichiometric excess of oxygen or an oxidizing agent. The catalyst used in the process of the invention is a mixed oxide of iron and cobalt selected from the group consisting of (a) CoIIxFeII1-xFeIII2O4 where x normally has values 0/=x/=1 and, (b) CoIICoIII(x-1)FeIII(3-x)O4 where x normally has values 1/=x/=3.
