We investigated vanadium (V) loading effects on selective catalytic reduction (SCR) activity and $SO_2$ resistance using commercial SCR catalysts applied on a power plant and incinerator with different amounts of V loading. These catalysts were characterized using XRD, Raman, ICP, BET analysis and found to contain $TiO_2$ (anatase) supported $V_2O_5$ added $WO_3$ and $SiO_2$. The SCR activity of the catalysts increased by increasing either the $V_2O_5$ or the $WO_3$ loading amounts; the SCR activity of the catalysts added $WO_3$ is higher than that of $WO_3$-free catalysts. As the V loading amount in the catalyst increased, the $SO_2$ durability decreased. The $V_2O_5$ supported $TiO_2$ catalyst added $WO_3$ and $SiO_2$ inhibits the deactivation process by $SO_2$. The $SO_2$ resistance of catalysts added $SiO_2$ is higher than that of catalysts added $WO_3$.
