Removal of Thiophene from Simulated Oil by Catalytic Oxidation Using K2FeO4/ V2O5
Oxidation extraction of thiophene from simulated oil by using K2FeO4 as oxidant and methanol as extractant has been investigated. The effects of different catalyst, oxidant amount, catalyst amount, reaction temperature, reaction time, and extraction conditions were studied. This process is capable of decreasing the sulfur content of simulated oil from 100 mg•L-1 to 17.8 mg•L-1 at the optimal conditions. The results indicate that such a process could be an alternative to common hydrodesulfurization for deep desulfurization.
