Research output: Contribution to conferencePaperpeer-review


The positive effect of deposited vanadium on reducing FCC naphtha sulfur content has been gradually realized and come to be affirmed during FCC process. A study was carried out to determine the appropriate method by adding vanadium oxide in FCC catalyst. The interaction between vanadium oxide and its supports could induce new active sites, e.g., Lewis acid sites with proper acid strength and V-O-M (support) bond with active oxygen. The former benefited the selective adsorption of thiophene in the presence of cyclohexane while the latter benefited the oxidation of thiophene to SO2. This is an abstract of a paper presented at the 41st Annual Loss Prevention Symposium (Houston, TX 4/22-26/2007).
