Role of water in the partial oxidation of propane to acrylic acid over Mo1V0.3Te0.23Nb0.12Ox catalyst
Effects of water on the catalytic performances of MoVTeNbO catalyst in the oxidation of propane to acrylic acid have been investigated at different reaction temperatures and different steam contents. Obtained results show that both catalytic performances and catalyst structure are very sensitive to the presence of water vapor in the reaction feed. Presence of water induces some structural modif...

متن کاملKinetics and Mechanism of Ethane Oxidation to Acetic Acid on Catalysts Based on Mo-V-Nb Oxides
Kinetic and isotopic studies showed that C-H bond activation in ethane by surfaces essentially saturated with lattice oxygens is the sole kinetically relevant step in ethane oxidation on Mo-V-NbOx mixed oxides. These conclusions are consistent with the dependence of oxidation rates on O2 and C2H6 pressures, with H/D exchange and kinetic isotope effects, and with the preferential initial incorpo...

متن کاملEffect of Catalyst Structure on Oxidative Dehydrogenationof Ethane and Propane on Alumina-Supported Vanadia
The catalytic properties of Al2O3-supported vanadia with a wide range of VOx surface density (1.4-34.2 V/nm) and structure were examined for the oxidative dehydrogenation of ethane and propane. UV-visible and Raman spectra showed that vanadia is dispersed predominately as isolated monovanadate species below ~2.3 V/nm. As surface densities increase, two-dimensional polyvanadates appear (2.3-7.0 ...
