Abstract
Improved methods of oxidative dehydrogenation (ODH) of short chain alkanes or ethylbenzene to the corresponding olefins, and improved methods of oxidative coupling of methane (OCM) to ethylene and/or ethane, are disclosed. The disclosed methods use boron- or nitride-containing catalysts, and result in improved selectivity and/or byproduct profiles than methods using conventional ODH or OCM catalysts.
