氧气氧化脱除模拟汽柴油中的稠环噻吩类硫化物
Oxidation of Sulfur Compounds in Model Fuel with Oxygen
摘要
Abstract
In a system without catalysts,oxygen reacted with octane to produce hydroperoxides in-situ,which were used as oxidants to oxidize the sulfur compounds in the model fuel.A detailed parametric study was performed with different reac-tion temperature,reaction time,and initial oxygen partial pressure,to investigate their effects on the removal of dibenzothio-phene(DBT)and thiophene(Th).The removal of DBT could reach 98.4%, at 140,℃,after 4,h,with initial oxygen partial pressure at 0.4,MPa.The removal of thiophene can reach 81.8%, at 150,℃,after 4,h,with oxygen partial pressure at 0.8,MPa.The white crystals were characterized by FTIR and1H NMR,and identified as dibenzothiophene sulfone(DBTO2).关键词
