Potassium ferrate is prepared by an improved hypochlorite oxidation method and then characterized. A new, effective and green approach for ultralow-sulfur pentane production is proposed using potassium ferrate as oxidant. Effects of oxidation conditions on the desulphurization and the oxidation mechanism are discussed. With 0.1786 g of K_2FeO_4. 0.5 mL of ZSW-1 catalyst, 20 mL of pentane under 30℃ for 60 min, the reaction mixture was extracted with 5%NaOH aqueous solution, the sulphur content was reduced from 50 mg/L to 0.632 mg/L, and the desulfurization ratio reached to 98.7 %.
