Synthesis, characterization and application of some non-halogen ionic liquids as green solvents for deep desulfurization of diesel oil
http://repository.vnu.edu.vn/handle/VNU_123/28392
Some
non-halogen ionic liquids (1-n-butyl-3-methylimidazolium hydrosulphates
([BMIM][[HSO4]), 1-n-butyl-3-methylimidazolium acetate ([BMIM][CH3COO]),
1-n-butyl-3-methylimidazolium dibutyl phosphate ([BMIM][DBP]),
1-n-octyl-3-methylimidazolium hydrosulphates ([OMIM][HSO4]), and
1-n-octyl-3-methylimidazolium acetate ([OMIM][CH3COO])) were synthesized, characterized,
and used as solvents for extraction of sulfur compounds in model oils.
All
investigated ionic liquids show high desulfurization performance from the model
oils.
The
influence of factors such as the structures of ionic liquid anions and cations,
and the structure of sulfur compounds on the deep desulfurization was
inves-tigated.
Some
ionic liquids with high, mild and low desulfurization ability ([OMIM][CH3COO],
[BMIM] [DBP], and [BMIM][[HSO4], respectively) were used as solvents to extract
sulfur compounds in diesel oil.
The
residual sulfur contents in diesel oil meet Euro III and Euro IV standards
after five or six extraction cycles corresponding to a desulfurization
efficiency of approximately 97%.
The
combination of oxidation reagents and [BMIM][HSO4] or [BPy][HSO4] increases the
desulfurization efficiency.
The
used ionic liquids were recovered by re-extraction of sulfur compounds and
oxidation products of DBT from ionic liquid
