A renewed interest of benchmark V2O5/WO3/TiO2 SCR-catalysts is discernible for the depollution of stationary sources jointly with the use of bio-fuels as substitute to fossil fuels. However, the resistance to deactivation has to be reconsidered according to additional alkaline contamination. This study tried to elucidate the impact of potassium on the stability of vanadate and tungstate species at...
The development of more thermally stable vanadia-based SCR catalysts for combined end-of-pipe technologies, i.e. selective catalytic reduction catalysts wash-coated on a particulate filter, has been considered in this study. The impact of thermal aging at 850 °C in wet atmosphere has been investigated on bulk W-doped CeVO4 catalysts. Strong detrimental effect on the specific surface area was observed...
