<p>PURPOSE:To improve denitration efficiency and reduce the amount of denitration catalyst by adding NH3 and H2O2 to waste gas and passing the gas through the denitration catalysts. CONSTITUTION:NH3 and H2O2 are added through flow passages 2, 3 to a harmful waste gas contg. NOx flowing through a flow passage 1. The NH3 and H2O2 to be added may be in the form of either liquid or gas and it is equally well to dilute these by using air or an inert gas as a carrier gas. The catalyst to be packed in the catalyst packed layer may be any of commonly used catalysts for denitration.</p> |
