摘要：
A strong promoting effect of the presence of C3H8 or C3H6 was determined for the CH4-SO2-O-2 reaction, over pre-sulfated 1%Pt/gamma-Al2O3 and pre-sulfated 1%Pt-2%Sn/gamma-Al2O3 catalysts. These results suggest that over 1%Pt-2%Sn/gamma-Al2O3 catalysts, small amounts of propane or propylene in the gas feed may eliminate methane emissions at low temperatures from lean-burn NGV exhausts.
