Mechanistic study of propane selective oxidation with H2 and O2 on Au/TS-1

Abstract. The selective oxidation of propane to acetone and 2-propanol with H2 and O2 was studied on Au/TS-1 by kinetic and spectroscopic analysis. A kinetic study using a factorial design at conditions where the catalyst was stable and gave propane conversions of 90%, resulted in a power-rate law expression of the form roxyg. = koxyg.(H2)0.74(O2)0.36(C3H8)0.29. In situ Au L3-edge X-ray ab…
