| 摘 要： | 以油溶性过氧化羟基异丙苯(CHP)为氧化剂,Al2O3为催化剂,引入超声作用,以正辛烷为模拟油品对油中二苯并噻吩的氧化进行了研究。考察了反应温度、反应时间、催化剂用量、氧硫比、超声功率对二苯并噻吩(DBT)降解率的影响并进行了正交实验,结果表明,各因素影响程度大小依次为:反应温度>催化剂用量>超声功率>反应时间>氧硫比,在反应温度为70℃,反应时间为45 min,氧硫比为5:1,催化剂用量为0.3 g,超声功率为60 W的最佳氧化条件下,DBT的降解率达到了88.0%。

| Abstract: | The oxidation of dibenzothiophene in octane was studied under ultrasonic irradiation by using oil-soluble cumyl hydroperoxide(CHP) as oxidant,alumina as catalyst.The influences of reaction temperature,reaction time,catalyst dosage,oxidant to sulfur(O/S) ratio and ultrasonic power on DBT degradation ratio were studied.The results showed that the effect of various factors on DBT degradation ratio lay in the order of reaction temperature > catalyst dosage > ultrasonic power > reaction time > O/S ratio.The opti... |
