Abstract

The possibility of removing sulfur-containing compounds from diesel fuel by extraction with ionic liquids (ILs) as extractants based on 1,3-dibutylimidazolium bromide and 1-butyl-3-octylimidazolium bromide and transition metal salts (Cu, Co, Ni, and Mn bromides and trifluoroacetates) has been considered. It has been shown that the use of extraction systems containing ILs and metal salts increases the degree of removal of sulfur compounds from diesel fuel. It has been suggested that metal salts with electron-withdrawing properties provide additional complexation with sulfur compounds of hydrocarbon feedstocks, which entails an increase in the extraction power of the extractant.

离子液体作为柴油含硫化合物的萃取剂

摘要

通过使用离子液体（ILs）作为溴化1,3-二丁基咪唑鎓和1-丁基-3-辛咪唑鎓溴化物以及过渡金属盐（Cu，Co，Ni和已经考虑了溴化锰和三氟乙酸盐。已经表明，使用含有离子液体和金属盐的萃取系统，可以提高从柴油中去除硫化合物的程度。已经提出，具有吸电子性质的金属盐提供了与烃原料的硫化合物的另外的络合作用，这导致萃取剂的萃取能力提高。
