Abstract:
1. A process for preparing an alkylate, where the process comprises: contacting in a reaction zone a hydrocarbon mixture comprising at least an isoparaffin and an olefin with an acidic ionic liquid catalyst under alkylation conditions to form an alkylate and solids in the reaction zone; withdrawing an alkylate-comprising effluent, comprising alkylate, solids and acidic ionic liquid catalyst, from the reaction zone; and treating at least part of the alkylate-comprising effluent to remove at least part of the solids to obtain a solids-depleted effluent, wherein the amount of solids removed from the alkylate-comprising effluent is sufficient to maintain the concentration of solids in the reaction zone at the most 5 wt %, based on the total weight of the acidic ionic liquid catalyst in the reaction zone.
