ABSTRACT

Nitrogen oxides (NOX) was emitted from flue gas of stationary sources and exhaust gas of mobile sources, can leads to various environments problems. Selective Catalysts Reduction (SCR) is the most effective NOX removal system. Commercial V2O5-WO3/TiO2 catalysts, usually containing V2O5 0.5~3 wt%, WO3 5~10 wt%, and V2O5 is active in the reduction of NOX but also in the desired oxidation of SO2 to SO3. To reduce the amount of vanadium, using graphene matrix supported vanadium to synthesize nanocomposite. Then, we fabricated to 1 inch honeycomb type of SCR catalysts adding graphene-vanadium nanocomposite. The chemical-physical characteristics and the catalytic activity were performed by XRD, XRF, BET and Micro-Reactor (MR). As a result, the De-NOX performance was showed, similar to the commercial catalyst activity as 77.8 % and using nanocomposite catalyst as 77.1 % at 350 o C.
