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 کاملDeactivation kinetics of V/Ti-oxide in toluene partial oxidation
Deactivation kinetics of a V/Ti-oxide catalyst was studied in partial oxidation of toluene to benzaldehyde (BA) and benzoic acid (BAc) at 523–573 K. The catalyst consisted of 0.37 monolayer of VOx species and after oxidative pre-treatment contained isolated monomeric and polymeric metavanadate-like vanadia species under dehydrated conditions as was shown by FT Raman spectroscopy. Under the reac...
متن کاملTransient kinetics of toluene partial oxidation over V/Ti oxide catalysts
Transient kinetics in the toluene oxidation over V/Ti oxide catalysts prepared by grafting and impregnation have been compared. V4+ cations are supposed to be the sites for the formation of electrophilic oxygen species participating in deep oxidation. Another oxygen species (probably nucleophilic) present on the oxidised catalyst surface are responsible for benzaldehyde formation. Selectivity o...
متن کاملPartial oxidation of toluene by O2 over mesoporous Cr–AlPO
The synthesis of mesoporous Cr–AlPO was carried out under hydrothermal conditions. Characterisation of the catalyst was done with low angle XRD, N2 adsorption, UV–VISDRS, ESR and thermal analysis. The catalytic activity was tested for partial oxidation of toluene with molecular oxygen in vapour phase. It was observed that Cr–AlPO functions both as acid and redox catalyst. 2002 Elsevier Science ...
