Verfahren zur katalytischen Reduktion von Stickoxiden
摘要
According to the inventive method for catalytic reduction of nitric oxides contained in the oxygen-containing flue gas from combustion facilities, ammoniac is added to flue gas at a temperature of 150 DEG to 950 DEG C. Said flue gas goes across a reaction chamber in which the catalyst used is natural zeolite, suspended with a catalytically active substance. In order to improve the catalytic reduction, the catalytically active substance is composed of metallic ions integrated to the zeolite lattice by a cation exchange.
