Abstract

The present invention provides a method of treating an exhaust gas comprising methane and NO. The exhaust gas is contacted with a catalyst in the presence of oxygen to oxidize at least part of the methane in the gas stream to carbon dioxide and water and at least part of the NO into NOobtaining a treated gas stream. The catalyst comprises one or more noble metals supported on non-modified zirconia, wherein the zirconia comprises tetragonal zirconia and monoclinic zirconia, and wherein the weight ratio of tetragonal zirconia to monoclinic zirconia is in the range of from 1:1 to 31:1.
