Embodiment Construction
[0039] Embodiments of the present invention provide a method for treating spent chloroaluminate-based ionic liquid catalysts, comprising the following steps:
[0040] The spent chloroaluminate-based ionic liquid catalyst is digested-neutralized with an alkaline solution until the system is neutral to weakly alkaline, and a three-phase mixture consisting of water phase / acid-soluble oil phase / floc is obtained;
[0041] The three-phase mixture is fully mixed with the organic coagulant and separated by sedimentation, and the acid-soluble oil phase of the upper layer and the floc phase of the bottom layer are respectively collected;
[0042] Transfer the floc phase to a thickener for concentration to form a concentrated slurry with a water content of 50-60wt%, part of the concentrated and precipitated aqueous solution provides a reaction medium for digestion-neutralization, and part is used for alkaline solution and organic coagulation aid Agent configuration; the concentrated slur...
