Název v původním jazyce

Comparison of the Catalytic Behaviour of V-Based Supported Catalyst for Oxidative Dehydrogenation of propane and Partial Oxidation of Crotonaldehyde

Popis výsledku v původním jazyce

The vanadium oxide supported catalysts (1 wt. % V on SiO2 (silica, aerosil), TiO2 - anatase, ZrO2, Al2O3 - ?× alumina, MgO) were prepared by impregnation method and characterized by means XRF, N2-BET, H2-TPR methods. The catalytic activity of these catalysts was tested in two different oxidation reaction: oxidative dehydrogenation of propane and partial oxidation of crotonaldehyde in gas phase. Prepared catalysts were active in both studied reactions, but the activity of the catalyst in each reaction was attributed to different catalytic active sites detected by means of H2-TPR. The activity of catalysts was correlated to its redox properties and selectivity to the main reaction products was correlated to the acid-base character of the supports. Reaction scheme for crotonaldehyde oxidation were suggested.
