EFFECT OF SUPPORT ON CATALYTIC CHARACTERISTICS OF V–Sb OXIDE SYSTEM IN THE PROCESS OF OXIDATIVE DEHYDROGENATION OF ISOBUTANE
It is shown that by influence on catalytic activity of Sb oxide systems the carriers are arranged in the following order: γ-Al2O3 > α-Al2O3>Si–Al–O>SiO2 ≈ MgO. As is indicated in the studied conditions (0.5–2 monolayer) change of a loading degree of V–Sb–O slightly influences on activity and selectivity of a catalyst. The best catalytic activity of V0.9Sb0.1Ox (γ-Al2O3) is explained by optimum interaction between a carrier surface and deposited components
