Propane epoxidation was carried out by sequential propane dehydrogenation–propylene epoxidation steps using a two-catalyst bed and H 2 and O 2 as the oxidant mixture. The propane dehydrogenation step used a Au/TiO 2 catalyst that was active at the low temperature (443 K) used for the propylene epoxidation step; the latter used a Au/TS-1 catalyst. In situ Au L 3 -edge...
The selective oxidation of propane to acetone and 2-propanol with H 2 and O 2 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 <6% and combined oxygenates selectivity of >90%, resulted in a power-rate law expression of the form r oxyg. = k...
