Catalytic Oxidation and Desulfurization of Calcium-Hydroxide Gypsum Wet Flue Gas Using Modified MIL-53(Fe)

MIL-53(Fe) was prepared and modified with benzoic acid to prepare MIL-53(Fe)-BA additive, which used improve the catalytic oxidation rate of sulfite, prevent scaling desulfurization tower, efficiency during wet flue gas (WFGD) process power plants. exhibits abundant Lewis sites because appearance coordination unsaturated Fe atoms. Due excellent sorption capacity, Ca(OH)2 as main SO2 desulfurizer. The composite desulfurizers were by mixing MIL-53(Fe)-based additives Ca(OH)2, characterized SEM, XRD, FT-IR. A unit set up at laboratory scale study effect on sulfite efficiency. results showed that addition can increase capacity 159%, greatly These broaden adaptability desulfurizing system high-sulfur coals, provide support for improving
