Preparation, Physiochemical and Kinetic Investigations of V2O5/SiO2 Catalyst for the Sulfuric Acid Production
V2O5/SiO2 catalyst was utilized to oxidize SO2 to SO3 species in the presence of oxygen mainly for producing sulfuric acid. For this catalyst, the active phase was a mixture of vanadium pentoxide and basic sulfate/pyrosulfate material. This active phase at the reaction temperature behaved as a liquid filling up the pores of the silica support. On the other hand, amounts of the SO3 and V5+ speci...

متن کاملOxidative desulfurization of light fuel oil by using hydrogen peroxide in the presence of acetic acid catalyst
Hydrogen peroxide as an oxidant agent was used for desulfurization of a petroleum hydrocarbon fraction (C10-C22) with boiling range of 175-375 ℃, (light fuel oil) in the presence of acetic acid as catalyst. The oxidation was performed in an ultrasonic bath. It is found that increasing the amount of hydrogen peroxide lead to increase the oxidation rate and so desulfurizatio...
