Abstract: A reactor apparatus and method for removing and/or reducing NOx, CO, carbon particulates and hydrocarbons from exhaust gases produced by industrial processes includes a reactor including an inlet plenum, a reaction chamber, an outlet plenum, and a heat exchanger wherein gases exiting the reaction chamber heat gases entering the reaction chamber. EGR is drawn through a cooling heat exchanger with an injection blower and is delivered through control valves to the reaction chamber, the inlet plenum and to an add fuel mixing chamber whereby mixed fuel and EGR is delivered to the reaction chamber. A feedback controller controls the flow valves responsive to the temperatures in the reaction chamber entrance and the outlet plenum.

Abstract: A system for reduction of noxious oxides from an exhaust of an internal combustion engine. The internal combustion engine includes an engine exhaust. A NOx catalytic reactor has at least one inlet in communication with the engine exhaust. A reductant catalytic reactor includes an inlet in communication with a reductant fuel supply, and an outlet in communication with at least one inlet to the NOx catalytic reactor.
