【摘要】：針對(duì)純鐵基離子液體(Fe-IL)在脫硫過程中氣液傳質(zhì)效率較低、鐵活性不高等缺陷導(dǎo)致的脫硫液易被擊穿、硫容小和再生緩慢等問題,以鐵基離子液體(Fe-IL)為基質(zhì),選用鋅基離子液體(Zn-IL)、錳基離子液體(Mn-IL)和1,3-二甲基咪唑啉酮(DMI)為助劑,調(diào)節(jié)相互之間的質(zhì)量比配制復(fù)合離子液體基脫硫液,并試驗(yàn)上述混合溶液的脫硫效果。實(shí)驗(yàn)結(jié)果表明,復(fù)合金屬離子液體之間具有協(xié)同強(qiáng)化脫硫的作用,1,3-二甲基咪唑啉酮對(duì)鐵基離子液體脫硫有著較好的活化作用,其中鐵鋅基離子液體與1,3-二甲基咪唑啉酮組成的復(fù)合液脫硫效果更為理想。
[Abstract]:In order to solve the problems of low gas-liquid mass transfer efficiency and low iron activity in the desulphurization process of pure iron-based ionic liquid (Fe-IL), the desulphurization solution is easy to be broken down, the sulfur capacity is small and the regeneration is slow. Using iron-based ionic liquid (Fe-IL) as matrix, zinc-based ionic liquid (Zn-IL), manganese-based ionic liquid (Mn-IL) and 1, 3-dimethyl Imidazolinone (DMI) as auxiliaries. The desulphurization effect of the mixed solution was tested by adjusting the mass ratio of each other to prepare the composite ionic liquid based desulphurization solution. The experimental results show that there is a synergistic effect of enhanced desulfurization between composite metal ionic liquids. 1, 3-dimethyl Imidazolinone has a good activation effect on desulphurization of iron-based ionic liquids, and the composite liquid composed of iron-zinc-based ionic liquids and 1, 3-dimethyl Imidazolinone has better desulphurization effect.
