Abstract: We provide a segmented reactor for regenerating a spent acidic ionic liquid via a hydrogenation reaction and hydrocracking, comprising: no solid hydrogenation catalyst; a gas inlet on one side for feeding a gas feed comprising a hydrogen; a liquid inlet on an opposite side for feeding a spent acidic ionic liquid; partitions along an axis of the reactor that create segments, wherein each segment functions as a bubble column reactor; and an outlet from which a regenerated acidic ionic liquid flows out of the segmented reactor.

Abstract: We provide a process for regenerating a spent acidic ionic liquid, comprising contacting the spent acidic ionic liquid with hydrogen and without an addition of a hydrogenation catalyst; wherein a conjunct polymer content is decreased in the spent acidic ionic liquid to produce regenerated acidic ionic liquid. We also provide a process for making an alkylate gasoline blending component, comprising: a) alkylating a mixture of isoparaffins and olefins using an acidic ionic liquid and an alkyl halide or a hydrogen halide, wherein a conjunct polymer accumulates in a spent acidic ionic liquid; and b) feeding the spent acidic ionic liquid and a hydrogen, and without an addition of a hydrogenation catalyst, to a regeneration reactor operated under selected hydrogenation conditions to produce a regenerated acidic ionic liquid that is used for the alkylating, wherein the conjunct polymer in the regenerated acidic ionic liquid is decreased by at least 50 wt %.

Abstract: Systems and apparatus for ionic liquid catalyzed hydrocarbon conversion, such as alkylation, using vaporization to remove reaction heat from an ionic liquid reactor and to provide mixing therein, wherein hydrocarbon vapors are withdrawn from the ionic liquid reactor and the withdrawn hydrocarbon vapor is recovered by a hydrocarbon vapor recovery unit in fluid communication with the ionic liquid reactor for recycling condensed hydrocarbons to the ionic liquid reactor. Processes for ionic liquid catalyzed alkylation are also disclosed.
