In the vital effort to curb industrial air pollution, sulfur dioxide (SO₂) remains a primary target for removal from flue gases. Calcium hydroxide (Ca(OH)₂) stands as a cornerstone reagent in many Flue Gas Desulfurization (FGD) systems due to its favorable cost-benefit ratio and widespread availability. However, to meet increasingly stringent environmental regulations and improve operational efficiency, many industries are looking beyond basic Ca(OH)₂ performance. NINGBO INNO PHARMCHEM CO.,LTD., a leading chemical manufacturer, offers innovative catalyst solutions designed to maximize the desulfurization potential of industrial calcium hydroxide.

The efficacy of Ca(OH)₂ in SO₂ capture is well-established, but its performance can be significantly augmented through the incorporation of specific catalytic materials. Research has shown that metal-organic frameworks (MOFs), such as modified MIL-53(Fe), act as highly effective oxidation catalysts for the intermediate calcium sulfite (CaSO₃) formed during the desulfurization process. These catalysts, when blended with Ca(OH)₂, promote the rapid conversion of CaSO₃ to calcium sulfate (CaSO₄), a more stable compound. This catalytic action is critical for preventing scale formation in equipment, a common issue that hinders continuous operation and reduces overall efficiency.

The key to this enhanced performance lies in the tailored structure of the catalysts. For instance, the MIL-53(Fe)-BA catalyst, developed by modifying MIL-53(Fe) with benzoic acid, introduces a higher concentration of Lewis acid sites (LAS). These sites are instrumental in adsorbing sulfur species and accelerating the oxidative processes. When integrated with Ca(OH)₂, these catalysts have demonstrated remarkable improvements, including a substantial increase in sulfite oxidation rates and a corresponding surge in desulfurization efficiency, often exceeding 99% in optimized conditions. For procurement managers seeking to buy advanced chemical additives, these results underscore the value proposition.
