Description
Summary:Gas phase thermal and oxidative dehydrogenation of ethane and propane are explored experimentally and mikrokinetically. Kinetic data for the elementary reactions postulated were adopted from the literature. The results show that oxygen plays a dominating role in the primary activation of the alkanes by producing an HO 2 and a hydrocarbon radical. The kinetic sequences developed predict satisfactorily conversion and products yields for ethane and propane oxidative dehydrogenation.
