Process of alkane oxidative dehydrogenation and/or alkene oxidation
The invention relates to a process of the oxidative dehydrogenation of an alkane containing 2 to 6 carbon atoms and/or the oxidation of an alkene containing 2 to 6 carbon atoms, wherein oxygen, water and the alkane and/or alkene are fed to a reactor and are contacted with a mixed metal oxide catalyst containing molybdenum, vanadium, niobium and optionally tellurium in the reactor, and wherein the molar ratio of water as fed to the reactor to oxygen as fed to the reactor is smaller than 1:1.
1. A process for the oxidative dehydrogenation of an alkane containing 2 to 6 carbon atoms and/or the oxidation of an alkene containing 2 to 6 carbon atoms, wherein oxygen, water and the alkane and/or alkene are fed to a reactor and are contacted with a mixed metal oxide catalyst containing molybdenum, vanadium, niobium and optionally tellurium in the reactor, and wherein the molar ratio of water as fed to the reactor to oxygen as fed to the reactor is smaller than 1:1 and the conversion of the alkane containing 2 to 6 carbon atoms and/or the alkene containing 2 to 6 carbon atoms is greater than 30%.
2. The process according to claim 1 , wherein the molar ratio of water as fed to the reactor to oxygen as fed to the reactor is of from 0.01:1 to smaller than 1:1.
3. The process according to claim 1 , wherein the total amount of water and oxygen as fed to the reactor is of from 10 to 80 vol.
4. The process according to claim 1 , wherein the molar ratio of the total amount of water and oxygen as fed to the reactor to the alkane containing 2 to 6 carbon atoms and/or the alkene containing 2 to 6 carbon atoms as fed to the reactor is of from 0.01:1 to smaller than 1:1.
