摘要

针对纯铁基离子液体（Fe-IL）在脱硫过程中气液传质效率较低、铁活性不高等缺陷导致的脱硫液易被击穿、硫容小和再生缓慢等问题，以铁基离子液体（Fe-IL）为基质，选用锌基离子液体（Zn-IL）、锰基离子液体（Mn-IL）和1，3-二甲基咪唑啉酮（DMI）为助剂，调节相互之间的质量比配制复合离子液体基脱硫液，并试验上述混合溶液的脱硫效果。实验结果表明，复合金属离子液体之间具有协同强化脱硫的作用，1，3-二甲基咪唑啉酮对铁基离子液体脱硫有着较好的活化作用，其中铁锌基离子液体与1，3-二甲基咪唑啉酮组成的复合液脱硫效果更为理想。

Abstract

Based on the natural feature of Fe-based ionic liquids (Fe-IL)

non-aqueous wet oxidation desulfurization of hydrogen sulfide was proposed in our preliminary work. But it has the poor gas-liquid mass transfer and low concentration of active Fe(Ⅲ)

which leads the desulfurizing agent to be inactivated easily

and presents lower sulfur capacity and regeneration rate during the desulfurizing process. In this work

Fe-IL was used as bulk solution

Zn-based ionic liquids(Zn-IL)

Mn-based ionic liquids(Mn-IL) and 1

3-dimethyl ketone of imidazoline (DMI) are selected as additives with different mass ration to construct complex ionic liquids to improve desulfuring performance. According to the results

the complex ionic liquids with bimetal show much better desulfuring performance

and a stronger intensified effect of DMI on improvement of desulfuring performance is observed after the introduction of DMI into Fe-IL. Particularly

the ternary system of DMI and Zn-IL in Fe-IL presents the best desulfuration performance.
