    摘要: A regeneration process for re-activating an ionic liquid catalyst, which is useful in a variety of reactions, especially alkylation reactions, and which has been deactivated by conjunct polymers. The process includes a reaction step and a solvent extraction step. The process comprises (a) providing the ionic liquid catalyst, wherein at least a portion of the ionic liquid catalyst is bound to conjunct polymers; and (b) reacting the ionic liquid catalyst with aluminum metal to free the conjunct polymers from the ionic liquid catalyst in a stirred reactor or a fixed reactor. The conjunct polymer is then separated from the catalyst phase by solvent extraction in a stirred extraction or packed column.

    摘要: Disclosed herein are processes in which precipitation permits removal of metal halides (e.g. AlCl3) from ionic liquids. After precipitation, the precipitated metal halides can be physically separated from the bulk ionic liquid. More effective precipitation can be achieved through cooling or the combination of cooling and the provision of metal halide seed crystals. The ionic liquids can be regenerated ionic liquid catalysts, which contain excess metal halides after regeneration. Upon removal of the excess metal halides, they can be reused in processes using ionic liquid catalysts, such as alkylation processes.
