The products of oxidative dehydrogenation of paraffins were corresponding olefins, CO and CO2, in the propane reaction only a small part was cracked to ethylene and methane. Besides CO and CO2, the ammoxidation of ethane yielded ethylene and acetonitrile, and of propane brought propylene and acetonitrile too. Presence of ammonia increased substantially the paraffin conversion as well as selectivity and yield of the sum of olefin and nitrile for CoH-BEA and CoH-MFI zeolites, while with CoNa-zeolites the paraffin conversion and selectivity were similar.
