【Abstract】 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 K2FeO4,0.5 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%.更多还原
