【摘要】：以硝酸铋为催化剂,1-甲基咪唑四氟硼酸盐离子液体([HMIM]BF_4)为萃取剂和助催化剂,H_2O_2为氧化剂氧化脱除模拟油中的二苯并噻吩(DBT)。考察了反应温度、H_2O_2用量、催化剂用量、离子液体用量对脱硫率的影响。结果表明,在模拟油5mL、硝酸铋加入量0.02g、[HMIM]BF_4加入量1.0mL、H_2O_2加入量0.3mL、反应温度80℃、反应时间180min的最佳条件下,模拟油的DBT脱除率可以达到99.5%。催化剂循环使用5次活性无明显下降。对硝酸铋的氧化脱硫机理进行了解释。
[Abstract]:Using bismuth nitrate as catalyst, 1-methylimidazolium tetrafluoroborate ionic liquid ([HMIM] BF _ 4) was used as extractant and co-catalyst H _ 2O _ 2 as oxidant to remove dibenzothiophene dithiophene (DBT) from simulated oil. The effects of reaction temperature, H _ 2O _ 2, catalyst and ionic liquid on the desulphurization rate were investigated. The results show that under the optimum conditions of simulated oil 5mL, bismuth nitrate 0.02g, [HMIM] BF_4 1.0mLH2O2 0.3mL, reaction temperature 80 鈩，
