Abstract
A system for reducing nitrogen oxides from an exhaust fluid is provided. The system includes an exhaust source, a hydrocarbon reductant source, a first injector in fluid communication with the hydrocarbon reductant source, where the first injector receives a first hydrocarbon reductant stream from the hydrocarbon reductant source, and expels the first portion of the hydrocarbon reductant stream. The system further includes a first catalyst that receives the exhaust stream and the first hydrocarbon reductant stream, a second injector in fluid communication with the hydrocarbon reductant source, where the second injector receives a second hydrocarbon reductant stream from the hydrocarbon reductant source, and expels the second hydrocarbon reductant stream, and a second catalyst disposed to receive an effluent from the first catalyst and the second portion of the hydrocarbon reductant stream.
