Abstract

Abstract:

V₂O₅-WO₃/TiO₂ catalysts were prepared by a wet impregnation method, and the deactivation by KCl of their catalytic activity for selective catalytic reduction of NO_x by NH₃ (NH₃-SCR) was investigated. The fresh and poisoned catalysts were characterized by inductively coupled plasma (ICP), N₂ adsorption, Raman spectroscopy, H₂ temperature-programmed reduction, IR spectroscopy of adsorbed NH₃, and NH₃ oxidation. Vanadia species, which are the active sites for the SCR reaction, were turned into inert potassium vanadate, but they were partially maintained on the catalyst at a high vanadia loading. Tungsten oxide acts as a sacrificial agent that reacts with potassium to form potassium tungstate in addition to its roles in increasing the surface acidity of the catalyst and facilitating the dispersion of vanadia. The V₂O₅-WO₃/TiO₂ catalyst at a high vanadia loading exhibited the best resistance to alkali poisoning.

Key words: Vanadia, Tungsten oxide, Selective catalytic reduction, Alkali deactivation, Active site, Sacrificial agent
