CoH(Fe)-BEA zeolite exhibited a substantial increase in propene yield (from 2.0 to 6.8%), if together with molecular oxygen, nitrous oxide was used. No other oxygenates were detected. With increasing concentration of molecular oxygen in the propane/nitrous oxide/oxygen mixture, a synergetic effect of oxygen and nitrous oxide resulting in nearly threefold increase in propene yield was observed. At the reaction conditions studied, the highest propane conversion (15.8%) with 61.9% selectivity to propene and propene yield of 9.8%, and the sum of selectivities to oxygenates of 10.3% (foremost propyl alcohol and propanal) was achieved with the steamed H(Fe)-MFI zeolite when a mixture of nitrous oxide and oxygen was used.
