  • Exhaust gas catalyst composition
    Patent number: 8716172
    Abstract: Catalyst composition represented by the general formula REVO/S wherein RE is at least one of the group of rare earth metals Y, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Er and Yb in an amount of up to 6.0 wt.-%; V is vanadium in an amount of 0.2-2.5 wt.-%; O is oxygen in an amount of up to 3.5 wt.-%; and S is a support containing TiO2 in an amount of at least 70 wt.-%, with the rest being WO3 and optionally SiO2. This catalyst composition shows high removal efficiencies for NOx even after aging at 750° C.
