Abstract:  

Deep desulfurization of coked gasoline was investigated by oxidation-extraction process with quaternary ammonium phosphomolybdate and formic acid as catalysts, hydrogen peroxide as the oxidant and furfural as the extractant. The effects of the oxidant volume, catalyst amount, extractant volume, reaction time and temperature to the desulphurization of coked gasoline were investigated. Improved desulphurization capacity of catalytic oxidation-extraction process for coked gasoline was obtained by optimizing the process conditions. Therefore, optimum conditions have been got in the actual desulfurization process of coked gasoline. The optimum technological conditions are as following: reaction time is 60 min, reaction temperature is 70 ℃, oxidant volume is 2.5 mL, extractant volume is 50 mL, catalyst amount is 0.4 g.

摘要： 以过氧化氢、甲酸为氧化剂,磷钼酸季铵盐为催化剂,糠醛为萃取剂,通过催化氧化和萃取结合的方
法进行了焦化汽油脱硫实验。考察了过氧化氢体积、催化剂质量、萃取剂体积、反应时间和反应温度对汽油脱硫率
的影响。通过优化工艺条件提高了焦化汽油催化氧化脱硫的能力,结合生产实际得出焦化汽油脱硫的最佳工艺条
件。最佳工艺条件为:反应时间60min,反应温度70℃,萃取剂体积为50mL,氧化剂体积为2.5mL,催化剂质量为
0.4g。
