Abstract: A non-vanadium based metal oxide catalyst composition is provided. The catalyst composition comprises at least one metal oxide, comprising manganese oxide and being dispersed on the support, and a support comprising particles of composite oxide of aluminum and at least one metal selected from cerium, manganese and titanium, wherein aluminum is present in the composite oxide in an amount of from 50% to 80% by weight, calculated as Al2O3, based on the total weight of the composite oxide, and wherein manganese oxide is present in the metal oxide catalyst composition in an amount of from 2.5% to 10% by weight, calculated as MnO2, based on the total weight of the metal oxide catalyst composition.
