摘要/Abstract

摘要：

考察了以H₂O₂为氧化剂, 过氧磷钨酸为催化剂催化氧化脱除模拟油中的含硫化合物苯并噻吩(BT)和二苯并噻吩(DBT). 讨论了催化剂用量、反应温度、反应时间和剂油体积比等因素对反应的影响. 实验结果表明, 当催化剂用量为0.48%(质量分数), V(H₂O₂)∶V(Oil)=1∶50, 反应时间为60 min, 反应温度为60 ℃时, BT的脱除率达到96.48%, DBT的脱除率达到99.42%. 动力学研究结果表明, 过氧磷钨酸为催化剂的氧化脱除模拟油中的含硫化合物的反应为表观一级反应.

Abstract:

Catalytic oxidation desulfurization of thiophene-type sulfides, benzothiophene(BT) and dibenzothiophene(DBT), in simulated oil using H₂O₂ as oxidant and quaternary ammonium peroxotungsto phosphate as the catalyst was investigated. Effect of amount of catalyst, reaction temperature, reaction time and oxidant/oil volume ratio on catalytic oxidation desulfurization was investigated. The results show that the conversions of dienzothiophene and benzothiophene reach above 96.48% and 99.42% respectively, under the conditions of amount of catalyst 0.48%, H₂O₂/Oil volume ratio of 1∶50, temperature of 60 ℃ after reaction 60 min. The kinetic study indicate that catalytic oxidation desulfurization of simulated oil over peroxy phosphotungstic acid is pseudo first-order reaction.
