CNG(Compressed natural gas) oxidation reaction was performed over PtPd/γ-Al2O3 catalyst. THC(Total hydrocarbon) concentration and conversion was detected in order to study the reduction of methane and formaldehyde from the CNG gas by using catalyst. LOT(Light off temperature) is very important for the performance of low temperature oxidation of catalyst. LOT of 1Pt3Pd/γ-Al2O3 catalyst was 365℃. It is very low temperature compared to commercial catalyst which LOT is over 400℃ normally. THC conversion was 92 % at 400℃ over 1Pt3Pd/γ-Al2O3 catalyst. It showed that 1Pt3Pd/γ-Al2O3 catalyst is competitive and effective for the performance of low temperature oxidation of CNG engine emission.
