VANADIUM PHOSPHATE SUPPORTED CATALYSTS FOR ETHANE OXIDATIVE DEHYDROGENATION

抄録

TiO₂ and Al₂O₃ supported VOPO₄ was studied as catalyst for the oxidative dehydrogenation of ethane in the temperature range 450-550°C. The catalytic performances were dramatically enhanced with respect to bulk VOPO₄ as result of modified redox properties. Catalytic activity and selectivity to ethylene are associated to the presence of reduced vanadium, whose formation occurs during the reaction and is favoured by high temperature.
