以氧气作为氧化剂,开展催化汽油氧化萃取脱硫实验及氧化动力学研究.实验结果表明,氧气氧化萃取脱硫对催化汽油具有较好的脱硫效果;随着相转移催化剂用量增加、温度提高、氧气分压增大、时间延长、水与汽油体积比增大,汽油脱硫率持续提高,而汽油收率呈现降低的变化趋势.根据反应动力学方程和萃取相平衡原理,确定了脱硫率和汽油收率模型,并开展模型参数估值、统计检验和预测分析.研究结果显示,所建模型具有较高的模拟精度,预测结果与脱硫实验结果的变化趋势相同.

Using oxygen as oxidant,the desulfurization of catalytic cracking gasoline by oxygen oxidation and solvent extraction is carried out,and oxidation kinetics is also studied.The experimental results show that the conversion of organic sulfides goes up with increasing amount of phase transfer catalyst,oxidation temperature,oxygen pressure,reaction time and the ratio of water to gasoline.The enhancement of oxidation conditions is in favor of desulfurization rate,but leads to decrease of gasoline recovery yield.Based on oxidation kinetics and principles of extraction phase equilibrium,two models,one for desulfurization rate and the other for gasoline recovery yield,are deduced.The parameters in the models are calculated and statistical test is carried out.The prediction analysis with the models show that both fit well with experimental results.
