Sulfur dioxide absorbent comprising ionic liquid
摘要:
A sulfur dioxide absorbent comprising an ionic liquid comprised of alkyl ether-substituted imidazolium cation and an alkanesulfonate anion moieties possesses a high thermal/chemical stability, high SO2 absorption rate and low regeneration temperature, and is useful for an effective separation of SO2 from a combustion exhaust gas mixture or the like.
