초록

HC-SCR was conducted using Fe/ZSM5 catalyst coated over 200 cpi cordierite in the conditions of atomspheric pressure and 200℃-500℃. Among the tested hydrocarbon reductants, isobutane (i-C_4H_10) showed the highest de-NO_x yield of 69% at 320℃ with the mole ratio of reductant/NO_x =1.0. De-NO_x yield resulted by the change of alkane reductant was increased as the carbon number of alkane reductant was increased. The order of increase of de-NO_x yield was proportional to the order of decrease of bonding energy between C and H of reductant, where the H abstraction step from alkane molecule could be the rate controlling step of HC-SCR.
