    摘要: The present invention aims to eliminate the mounting of an independent ammonia oxidation catalyst to an exhaust passage. A selective reduction catalyst comprises a catalyst support 23 in which a plurality of through holes 23b partitioned by porous walls 23a are formed and a first active component 24 carried by the walls which dissolves nitrogen oxide contained in the exhaust gas by the reaction with ammonia. Inlet portions 23c and outlet portions 23d, adjacent to each other, of the plurality of through holes 23b are alternately sealed, and the wall 23a carrying the first active component 24 has ventilation and a second active component 26 having a catalytic action so as to oxidize ammonia having passed the wall is carried on the inner surface of the though hole. An exhaust gas purifier is provided with the selective reduction catalyst 22, a liquid injection nozzle 29 which is provided on the upstream side and can inject urea liquid 32, and an oxidation catalyst 53 provided at the exhaust pipe 16 on the upstream side.

    摘要: A method of decreasing pollutants produced in a combustion process. The method comprises combusting coal in a combustion chamber to produce at least one pollutant selected from the group consisting of a nitrogen-containing pollutant, sulfuric acid, sulfur trioxide, carbonyl sulfide, carbon disulfide, chlorine, hydroiodic acid, iodine, hydrofluoric acid, fluorine, hydrobromic acid, bromine, phosphoric acid, phosphorous pentaoxide, elemental mercury, and mercuric chloride. Oil shale particles are introduced into the combustion chamber and are combusted to produce sorbent particulates and a reductant. The at least one pollutant is contacted with at least one of the sorbent particulates and the reductant to decrease an amount of the at least one pollutant in the combustion chamber. The reductant may chemically reduce the at least one pollutant to a benign species. The sorbent particulates may adsorb or absorb the at least one pollutant. A combustion chamber that produces decreased pollutants in a combustion process is also disclosed.

    摘要: NOx and SO3 emissions from combustion of a sulfur containing carbonaceous fuel are reduced simultaneously. The combustion gases comprising NOx and SO2 are mixed with a NOx control agent into the combustion gases at a point upstream of a selective catalytic reduction catalyst for reduction of NOx. Following an SCR catalyst or other equipment that can oxidize SO2 to SO3 and prior to contact with an air heater for heating incoming combustion air, magnesium hydroxide is introduced in amounts and with droplet sizes and concentrations effective to form nano-sized particles in the effluent and reduce SO3 caused by the oxidation of SO2 in the catalyst. Computational fluid dynamics is employed to determine flow rates and select reagent introduction rates, reagent introduction location(s), reagent concentration, reagent droplet size and/or reagent momentum.
