Research progress on selective catalytic reduction (SCR) catalysts for NOx removal from coal-fired flue gas

Shilin Zhao et al.

Summary: This study comprehensively discusses SCR catalysts with different supports, including their preparation method, composition, deNOx ability, etc. The findings show that metal-based SCR catalysts have good performance in both high and low-temperature deNOx, carbon material as a carrier can enhance deNOx ability, and minerals-based SCR catalysts have good deNOx capacity at medium to low temperature. The good distribution of active elements, chemical adsorption, acid sites, and surface pore structure are crucial for the deNOx ability of catalysts.

Effect of WO3 and MoO3 doping on the interaction mechanism between arsenic oxide and V2O5-based SCR catalyst: A theoretical account

Yang-wen Wu et al.

Summary: In this study, the interaction mechanism between arsenic oxide (As2O3) and V2O5, WO3, and MoO3 doped catalysts was explored using density functional theory. It was found that MoO3 doped catalysts exhibit higher reactivity and stronger charge transfer with As2O3 compared to WO3 doped catalysts, providing better anti-arsenic poisoning effect. The results suggest that MoO3 doping can protect V2O5 from arsenic poisoning by promoting the reaction with As2O3.

Regeneration of alkali poisoned TiO2-based catalyst by various acids in NO selective catalytic reduction with NH3

Xiaoxiang Wang et al.

Summary: Acid regeneration effectively removed potassium deposits on the surface of the K-CuNbTi catalyst, resulting in excellent catalytic performance at high temperatures. The increase in acidic sites and generation of Bronsted acid sites were crucial factors contributing to the improved catalytic activity of the regenerated catalyst.

Kinetic and Mass Transfer Effects of Fly Ash Deposition on the Performance of SCR Monoliths: A Study in Microslab Reactor

Aldo Lanza et al.

Summary: The deposition of ashes over the catalysts was identified as the major cause of performance loss in the selective catalytic reduction (SCR) reactors. Scratching the surface layer of the aged catalysts resulted in a significant recovery of the DeNO(x) removal efficiency.
