摘要: Abstract Supported vanadia catalysts were prepared on two TiO 2 /SiO supports, which contained 70% and 90% . The supports thermally stable up to 1023 K surface species formed them. supported characterized by Raman FTIR spectroscopy, XRD TPR. area of the was also determined. active for propane oxidative dehydrogenation (ODH) reaction most selective catalyst 6% vanadia, appeared be monolayer limit these supports. Furthermore, with in support more than containing kinetic parameters determined able explain variations conversion at iso-contact time selectivity iso-conversion different catalysts.
