摘要: A method comprises injecting a reductant stream comprising a hydrocarbon reductant and water into an exhaust chamber comprising a nitrogen oxide-containing exhaust stream; contacting a composition comprising the reductant stream and exhaust stream with a catalyst; and decreasing a concentration of the nitrogen oxide in the composition comprising the reductant stream and exhaust stream. An exhaust stream treatment system, comprises an exhaust chamber comprising a catalyst; an exhaust stream comprising a nitrogen oxide; and a reductant stream comprising a hydrocarbon reductant and water.
