摘　　要：以双氧水为氧化剂,研究混合戊烷催化氧化-萃取耦合脱硫技术,考察了催化剂及其用量、氧化剂用量、甲醇用量、反应温度和反应时间对混合戊烷脱硫效果的影响。结果表明,氧化和萃取过程可以相互促进达到更好的脱硫效果;在混合戊烷10 mL、双氧水0.1 mL、催化剂钨酸0.012 g、甲醇1.6 mL、温度70℃、时间50 min的条件下,混合戊烷中硫的质量浓度由187.3 mg/L降至7.9 mg/L,脱硫率可达95.8%。Production of low sulfur pentane by using the oxidized-extract coupling desulfurization was researched with H2O2as oxidant.The effects of the catalyst system,the amounts of H2O2and methanol,the reaction temperature and time on desulfurization rate of pentane mixture were studied.The results showed that the oxidation process and the extraction process could be promoted mutually,and a good result on desulfurization rate was obtained.Under the conditions of petane mixture 10 mL,H2O20.1 mL,tungstic acid catalyst 0.012 g,methanol 1.6mL,reaction temperature 70℃and reaction time 50 min,the sulfur content of pentane was reduced to 7.9 mg/L from 187.3 mg/L,and the desulfurization rate reached 95.8%.
