CARBONACEOUS CATALYST FOR FLUE GAS DESULFURIZATION, PROCESS FOR PRODUCING THE SAME AND USE THEREOF FOR REMOVAL OF MERCURY FROM EXHAUST GAS |
摘要 |
<p>A carbon-based catalyst for flue gas desulfurization is brought into contact with a flue gas containing at least SO 2 gas, oxygen and water vapor so that the SO 2 gas can react with the oxygen and the water vapor to form sulfuric acid which is to be recovered. On a surface of the carbon-based catalyst, iodine, bromine or a compound thereof is added, ion exchanged or supported and a water-repellent treatment is applied. The carbon-based catalyst can also be used as a mercury adsorbent for flue gas treatment for adsorbing and removing metallic mercury from a flue gas containing metallic mercury, SO 2 gas, oxygen and water vapor.</p> |
