Abstract:
A method of reducing NOx and/or CO/CO2 emissions from the combustion of a coal product or a hydrocarbon, which method comprises:burning a hydrocarbon in a combustor in association with a gas turbine to create hot gaseous combustion products; contacting said gaseous combustion products in the exhaust stream exiting said combustor while said stream is at a temperature of at least about 700Â° F. with particulate elemental iron to cause chemical and/or physical reactions to occur, whereby such reactions result in the production of solid iron oxide and/or iron carbide reaction products that are removed from an emission stream including the products of said combustion, and thereafter discharging said emission stream to the atmosphere downstream of said gas turbine.
