On the Mechanisms of Light Alkane Catalytic-Oxidation and Oxy-Dehydrogenation - An FT-Ir Study of the N-Butane Conversion over Mgcr2O4 and a Mg-Vanadate Catalyst
The interaction of n-butane, 1-butene, 1,3-butadiene and of C-4 oxygenates on the surface of oxidized Mg-chromite and Mg-vanadate catalysts has been studied by FT-TR spectroscopy. The results compare well with the catalytic behavior of these materials one of which is a combustion catalyst (MgCr2O4) and the other is a rather selective oxy-dehydrogenation catalyst (Mg-vanadate). A mechanism for these reactions is proposed.
