International Classification:

F01N 3/00

US Classification:

60286, 60274, 60287, 60292, 60295, 60297, 60301, 60303

Abstract:

The disclosed embodiments relate to a method and system for regeneration of a catalyst. The system includes an engine that creates an exhaust stream and a fuel supply adapted to supply a fuel stream to the engine. A reactor includes a catalyst and is in fluid communication with the engine to receive the exhaust stream. A sensor senses a system parameter and produces a signal corresponding to the system parameter. A controller receives the signal and directs at least a portion of the exhaust stream or at least a portion of the fuel stream to the catalyst to control a regeneration operation based on a value of the system parameter sensed by the sensor.

US Classification:

422170, 60299

Abstract:

Disclosed herein is a system for reducing NOemissions comprising a fuel tank in fluid communication with a fuel converter, wherein the fuel converter is located down stream of the fuel tank and wherein the fuel converter comprises a catalyst composition that is operative to continuously convert heavy hydrocarbon molecules having 9 or more carbon atoms per molecule into light hydrocarbon molecules having 8 or less carbon atoms per molecule; a selective catalytic reduction catalyst reactor in fluid communication with the fuel converter and located downstream of the fuel converter; and an engine in fluid communication with the fuel tank and the selective catalytic reduction catalyst reactor, wherein the engine is located downstream of the fuel tank and upstream of the selective catalytic reduction catalyst reactor.
