Název v původním jazyce
Study of vanadium based mesoporous silicas for oxidative dehydrogenation of propane and n-butane
Popis výsledku v původním jazyce
The comparative study of catalytic performance of V-containing high-surface mesoporous siliceous materials (HMS, SBA-16, SBA-15 and MCM-48) in oxidative dehydrogenation of propane and n-butane (C-3-ODH and C-4-ODH, respectively) was carried out. The aimof study was to investigate effect of silica support texture on the speciation of vanadium complexes and its impact on catalytic behavior in both above mentioned reactions is reported. Prepared catalysts were characterized by XRF for determination of vanadium content, XRD, SEM and N-2-adsorption for study of morphology and texture, and H-2-TPR and DR UV-vis spectroscopy for determination of vanadium complex speciation. All prepared materials were tested in propane and n-butane ODH reaction at 540 degrees C and obtained catalytic results were correlated with their structural and surface characteristics. On the basis of obtained data we conclude that the structure of mesoporous silica support plays decisive role in the case of application
