Synthesis and ultra-deep fast desulfurization performance of fiber based POM-ILs hybrid catalyst
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.
