Alkanes, light, oxidative dehydrogenation catalytic

After this paper was accepted for publication in November, 1992, a number of reports have appeared that deal with the subject of oxidative dehydrogenation of light alkanes. The effect of the structure of vanadia on a support has been investigated for the oxidation of butane [87J and propane [88-90], The evidence supports the concepts that the bridging oxygen in V — O — V plays an important role in the oxidation reaction [87, 90], The data also show that vanadia species of different structures on these supports have different catalytic properties, and that isolated V04 units are the most selective [91]. 

The gas-phase selective oxidative transformation of light alkanes is an important challenge as it could reduce the number of process steps, decreasing both the energy required and CO2 emissions, and improve the atom economy. In this chapter a summary of both the oxidative dehydrogenation and the O-insertion for C2-C4 alkanes is presented. In addition, an alternative method for abetter selective oxidative transformation of methane and a description of the best catalytic systems are discussed. 

The most difficult group of hydrocarbons to oxidize and one which until recently has resisted attempts at selective mild catalytic activation is the alkanes. Among those transformations currently desired (Fig. 30) are direct conversion of methane to methanol, formaldehyde, or higher hydrocarbons direct hydroxylation of light alkanes and smooth selective oxidative dehydrogenation of alkanes.
