Activity of Molybdenum Oxide Catalyst Supported on Al2O3, TiO2, and SiO2 Matrix in the Oxidative Dehydrogenation of n-Butane

Popis výsledku v původním jazyce

The catalytic oxidative dehydrogenation (ODH) of light alkanes has great potential to be used for production of alkenes instead of classically used steam cracking of naphtha. We report for the first time a comparison of molybdenum oxide species supportedon three different industrially relevant mesoporous supports-Al2O3, SiO2 and TiO2 in ODH of n-butane. All samples were prepared by wet impregnation and characterized by ICP-EOS for determination of molybdenum content, XRD and N-2-adsorption for study ofmorphology and texture, H-2-TPR and DR UV-vis spectroscopy for determination of molybdenum complex speciation and by NH3-TPD for study of acidity. All prepared materials were tested in n-butane ODH reaction at 540 degrees C and iso-conversion conditions. The molybdenum oxide supported on alumina exhibited the extraordinary high productivity (1.16 kg(prod) kg (-1)(cat) h(-1)) in ODH of n-butane which is one of the five highest C4-deh productivity values which were published for ODH of n-
