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 ...
The reaction of NO with CO on a catalyst of 0.5% Pt-3.4% MoO3 supported on a-Al2O3 was studied in different reactors at atm. pressure. A fixed-bed reactor with external recycle loop exhibited bistability and hysteresis as CO concn. or temp. were varied. In ...
Microchannel reactors promise to display unusually fast response behavior to sharp changes of feed compn. in heterogeneous catalytic systems. In an attempt to use this feature for the elucidation of the transient kinetics and possibly for performance enhan ...
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 ...
