Abstract
HC-SCR was conducted using Fe/ZSM5 catalyst coated over 200 cpi cordierite in the conditions of atomspheric pressure and $200^{\circ}C-500^{\circ}C$. Among the tested hydrocarbon reductants, isobutane (i-$C_4H_{10}$) showed the highest de-$NO_x$ yield of 69% at $320^{\circ}C$ 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.
