The prepn. of mesoporous Cr/AlPO was carried out under hydrothermal conditions. The catalyst was characterized by low angle XRD, N-adsorption, diffuse reflectance UV-visible spectroscopy, ESR and thermal anal. The catalytic activity was tested for vapor ph ...
Co-impregnation of vanadia and tungsta on titania produced highly active catalysts for the reduction of nitrogen oxides with ammonia but showed aging tendencies at temperatures around 600 °C. In order to preserve their low temperature activity after hydrot ...
A steady bubble plume model is developed to describe a weak air (or oxygen) bubble injection system used for the restoration of deep stratified lakes. Since the model is designed for two modes of operation, i.e., oxygenation and artificial mixing, gas exch ...
Real-world vanadium-based catalysts for the selective catalytic reduction (SCR) of NO with NH3 are occasionally exposed to high temperatures, which can induce catalyst aging. In this work, a 2.0 wt% V2O5/WO3-TiO2 catalyst based on commercial WO3-TiO2 was l ...
