Industrial processes, particularly those involving combustion of fossil fuels, are significant contributors to atmospheric sulfur dioxide (SO₂) pollution. This environmental concern necessitates effective Flue Gas Desulfurization (FGD) technologies. While calcium hydroxide (Ca(OH)₂) is a widely adopted desulfurizer due to its cost-effectiveness and availability, its performance can be further optimized. At NINGBO INNO PHARMCHEM CO.,LTD., we specialize in providing advanced chemical solutions, including novel catalytic additives, to elevate your desulfurization processes.

The inherent reactivity of Ca(OH)₂ with SO₂ forms calcium sulfite (CaSO₃) and subsequently calcium sulfate (CaSO₄). However, under certain conditions, such as the use of high-sulfur coal, incomplete oxidation of CaSO₃ to CaSO₄ can lead to scaling and reduced desulfurization efficiency. To address this, researchers have focused on catalytic oxidation additives that accelerate the sulfite oxidation process. Our MIL-53(Fe)-based catalysts, particularly those modified with benzoic acid (MIL-53(Fe)-BA), have demonstrated exceptional capabilities in this regard.

These modified metal-organic frameworks (MOFs) introduce enhanced Lewis acid sites (LASs) which act as catalysts. The increased LASs facilitate the rapid conversion of sulfite into sulfate, thereby mitigating the risk of scaling within desulfurization towers. Studies have shown that incorporating MIL-53(Fe)-BA can increase the oxidation capacity of sulfite by up to 159%. This translates to a significant improvement in the overall desulfurization efficiency, with reported increases from 89.2% to 99.1% when used as an additive at an optimal dosage. For industrial managers and procurement specialists looking to buy high-performance desulfurization solutions, these figures highlight the substantial operational benefits.

The adaptability of these advanced catalysts is another key advantage. By improving the system's inherent oxidation capacity, they enable the effective treatment of flue gases with higher SO₂ concentrations and varying coal sulfur content. This broadens the operational flexibility for power plants and other heavy industries.
