Isopropanol conversion over binary titan vanadium oxide catalysts
Abstract
Isopropanol conversion over binary titan vanadium oxide catalysts in the presence and absence of oxygen were studied. It was shown that acetone and propylene are the main products of the isopropanol dehydrogenation reaction over studied catalysts. It is established that in the isopropanol dehydrogenation reaction over titanium-vanadium oxide catalysts, the samples with an equimolar ratio of initial elements are highly active. In the dehydrogenation reaction of isopropyl alcohol in the presence of oxygen, except for the catalyst Ti-V=1-9, all other binary titanium-vanadium oxide catalysts have high activity in the propylene formation reaction. It was found that on binary titan-vanadium oxide catalysts in the isopropanol dehydrogenation reaction in the absence of oxygen, the increase in surface acidity leads to an enhancement in acetone yield and a lowering in propylene yield. In the isopropanol dehydrogenation reaction in the presence of oxygen, the change of surface acidity does not lead to a change in the yields of reaction products.
