摘要： A method for oxidizing mercury in combustion exhaust gas, which is excellent in oxidation activity and economic efficiency when changing metal mercury contained in combustion exhaust gas exhausted from a large boiler into mercury chloride, is provided. A method for oxidizing mercury in combustion exhaust gas comprises mercury in the combustion exhaust gas into mercury chloride in the presence of a chromium oxide catalyst supported with a magnesium oxide-aluminum oxide prepared by coprecipitating a magnesium salt, an aluminum salt and a chromium salt at a ratio of 1:1:1 and drying the coprecipitated material at 110 deg.C. The chromium oxide supported with the magnesium oxide-aluminum oxide is prepared by adding a magnesium salt, an aluminum salt, a chromium salt and a precipitant into water to form a precipitate and calcining the precipitate to a temperature from 300 to 700 deg.C under an air atmosphere.

摘要： PURPOSE: To increase absorption rate of acid gases such as SO2, CO2 from gas streams in the aqueous alkanolamine process where an absorbent mixture of MDEA, triethanolamine, dimethylethanolamine, and methyldiisopropanolamine is used, EDBEA (2,2-(ethylenedioxy)bis(ethylamine)) is added, as an absorption accelerator, to conventional ternary alkanolamine process. EDBEA has a primary amine group represented by NH2(CH2CH2O)nCH2CH2NH2 (n is an integer of 1 to 12) at both terminal ends, therefore it is possible to absorb quickly carbon dioxide across vapor-liquid interface. CONSTITUTION: An acid gas absorbent of the present invention is characterized by comprising ternary alkanolamine 20-50%, EDBEA (2,2-(ethylenedioxy)bis(ethylamine)) 0.5-5%, and the balance of water. Further, a scrubbing tower, for optimal operation with the acid gas absorbent, is preferably operated in the temperature range 40 to 60deg.C at a pressure of 1 to 2 atm.
