ABSTRACT:
A method for reducing NOxin lean exhaust gases to N2includes injecting a fuel into the exhaust gases and passing the exhaust gases and fuel mixture through a catalyst to reduce the NOxto N2. The catalyst may be (a) a perovskite compound, (b) at least one metal oxide impregnated with at least one precious metal, (c) a zeolite impregnated with at least one precious metal, or (d) a combination of a zeolite and at least one metal oxide impregnated with at least one precious metal.
