The oxidative desulfurization of naphtha has been investigated. An octane solution of benzothiophene (BT) was used as model naphtha. BT can be rapidly oxidized with hydrogen peroxide in the presence of acid catalysts in octane-acetic acid solutions. Peracetic acid formed in this oxidation system acts as an oxidizing agent to produce the sulfone of BT. This oxidation system can effectively reduce the sulfur content in straight-run naphtha. Pre-hydrodesulfurization of naphtha is effective for the deeper removal of sulfur by the oxidative desulfurization.
