SO2-Induced Alkali Resistance of FeVO4/TiO2 Catalysts for NOx Reduction

Zhiping Si et al.

Summary: This study reveals the phenomenon of K migration induced by SO2 on K-poisoned catalysts, which buffers the effect of alkali poison and restores activity, leading to an increased conversion of NOx. The sulfuration process helps to release the active sites poisoned by K2O, thereby enhancing the catalyst activity.

Simple physical mixing of zeolite prevents sulfur deactivation of vanadia catalysts for NOx removal

Inhak Song et al.

Summary: This study demonstrates that physically mixed H-Y zeolite can protect vanadium active sites effectively by trapping ABS in micropores, enabling the catalyst to operate stably at low temperatures and maintaining sulfur resistance during repeated aging/regeneration cycles. The pore structure and framework Al content of different zeolites play a crucial role in determining the trapping ability.

Bridging adsorption analytics and catalytic kinetics for metal-exchanged zeolites

Pengfei Xie et al.

Summary: By utilizing low-temperature reactive adsorption of NO to titrate copper-exchanged ZSM5, quantitative descriptors of the atomic structures and adsorption properties of Cu-ZSM5 were established, which were then applied to interpret the catalytic performance for NO decomposition. Linear correlations were established to bridge low-temperature adsorption analytics and high-temperature reaction kinetics, demonstrating their general applicability in understanding the structure-property relationships of metal-exchanged zeolites.

Improved NOx Reduction over Phosphate-Modified Fe2O3/TiO2 Catalysts Via Tailoring Reaction Paths by In Situ Creating Alkali-Poisoning Sites

Yue Li et al.

Summary: The issue of catalyst deactivation due to alkali poisoning remains a challenge for NOx reduction by NH3. A novel strategy of modifying Fe2O3/TiO2 catalysts with phosphate has been demonstrated to enhance NOx reduction in the presence of alkaline metals, by creating alkali-poisoning sites, increasing surface acidity, enhancing redox ability, and protecting active sites from alkali poisoning. This approach shows promise in providing inspiration for designing catalysts with exceptional resistance to alkaline metals for controlling NOx emissions.
