摘要
采用浸渍法将Keggin型P-Mo-W多金属氧酸盐(POM)与双离子液体结合在醋酸纤维素(CA)上,获得一种用于萃取氧化脱硫(EODS)的成型催化材料,采用响应面设计实验,探究温度、催化剂质量、氧硫比以及多酸负载量对脱硫的影响.研究表明,最佳脱硫反应条件为:模拟柴油25 mL,催化剂0.16 g,温度63 ℃,氧硫比4.8,多酸负载量1.08,反应2 h,可将模拟燃油中99.2%的DBT脱除.
Abstract
The Keggin-type P-Mo-W polyoxometalate(POM)with ionic liquids(ILs)have been facilely supported on cellulose acetate fiber(CA)through the impregnation method,obtaining a kind of molding catalytic material for the extractive oxidative desulfurization(EODS).The response surface design experi-ment was used to investigate the effects of temperature,catalyst mass,oxygen-sulfur ratio and polyacid loading on the desulfurization reaction.Research has shown that the optimal desulfurization reaction condi-tions were:simulated diesel oil 25 mL,catalyst 0.16 g,temperature 63 ℃,oxygen sulfur ratio 4.8,polyac-id loading 1.08,99.2%of DBT in simulated fuel can be removed after 2 h of reaction.
