Absorptionsmittel für Stickoxide und dessen Verwendung zur Reinigung von Belüftungsgas |
摘要 |
The present invention provides a nitrogen dioxide absorbent for the exhaust gas purifying facility designed to remove by absorption or adsorption of NO2 from a gas (such as ventilation gas from road tunnels) containing NOx in low concentrations. The absorbent is composed of a porous carrier and a basic amino acid and/or organic amine compound supported thereon. The absorbent is produced by impregnating a porous carrier sequentially with two aqueous solutions each containing in an amount of, for example, 0.5-3.0 mol/l (preferably 1.0-2.0 mol/l) of basic amino acid and 0.5-3.0 mol/l (preferably 1.0-2.0 mol/l) of organic amine compound, or impregnating a porous carrier with a solution containing 0.5-3.0 mol/l (preferably 1.0-2.0 mol/l) of basic amino acid and/or 0.5-3.0 mol/l (preferably 1.0-2.0 mol/l) of organic amine compound. |
