<p>PURPOSE:To efficiently remove SOx and NOx from gas by passing the gas through a bed packed with a molded compsn. obtd. by adding Fe2O3 and a stimulant to fine powder of water granulated slag and kneading them with water. CONSTITUTION:Fe2O3 and a stimulant such as cement, slaked lime or other alkali are added to fine powder of water granulated slag consisting of 41-43% CaO, 32-34% SiO2, 13-16% Al2O3, 5-8% MgO, 0.4-0.6% MnO, 0.2.-0.7% FeO and 0.8.-1.0% S as a carrier. They are kneaded with water, molded, hardened and dried to obtain a molded compsn. NOx and SOX are efficiently removed from gas by passing the gas through a bed packed with the molded compsn.</p> |
