摘要：
The kinetics of low temperature CO oxidation were studied over sequentially impregnated 1wt% Pt-0.25wt% SnOx supported on HNO3-oxidized activated carbon (AC3) using a wide range of CO (1-10 mol%) and O-2 (1-4 mol%) concentrations. Intrinsic kinetic data were obtained in the initial rates region at 383 K in the absence and presence of 5-45 mol% H-2 in the feed. A power-function rate expression with positive dependence on CO (0.96) and negative dependence on oxygen (-0.31) was obtained for the low temperature oxidation of CO. The effect of H-2 on CO oxidation rates was also investigated under similar conditions.
