Abstract:
A process for regenerating a spent ionic liquid catalyst including (a) applying a voltage across one or more pairs of electrodes immersed in a spent ionic liquid catalyst comprising conjunct polymer-metal halide complexes to provide freed conjunct polymers and a regenerated ionic liquid catalyst; and (b) separating the freed conjunct polymers from the regenerated ionic liquid catalyst is described. An alkylation process incorporating the regeneration process is also described.
Abstract:
A process for regenerating a used acidic ionic liquid catalyst comprising contacting the used ionic liquid catalyst with at teas! one metal in a regeneration zone in the absence of added hydrogen under regeneration conditions for a time sufficient to increase the activity of the ionic liquid catalyst is described. In one embodiment, regeneration is conducted in the presence of a hydrocarbon solvent.
Abstract:
A process for regenerating a used acidic ionic liquid catalyst comprising contacting the used ionic liquid catalyst with at least one 'regeneration' metal in a regeneration zone in the presence of added hydrogen under regeneration conditions for a time sufficient to increase the activity of the ionic liquid catalyst is described.

Abstract:
A process and method for making a superior lubricant or distillate fuel component by the oligomerization of a mixture comprising olefins to form an oligomer and the alkylation of the oligomer with isoparaffins to produce an alkylated ("capped") olefin oligomer preferably using an acidic chloroaluminate ionic liquid catalyst system. Preferably the ionic liquid catalyst system comprises a Bronsted acid.

Abstract:
A process for removing metal halides from regenerated ionic liquid catalyst comprising interacting a regenerated ammonium-based metal-halide ionic liquid catalyst or an ammonium-based metal-halide ionic liquid catalyst undergoing regeneration with either the parent ammonium halide salt from which the ionic liquid catalyst was made or a corresponding mixed salt having an ammonium halide to metal halide molar ratio of 0 to less than 2.0 is disclosed.
Abstract:
A process for the production of a high quality gasoline blending components from refinery process streams by the alkylation of light isoparaffins with olefins using an ionic liquid catalyst is disclosed. The alkylation process comprises contacting a hydrocarbon mixture comprising at least one olefin having from 2 to 6 carbon atoms and at least one isoparaffin having from 3 to 6 carbon atoms under alkylation conditions, said catalyst comprising a mixture of at least one acidic ionic liquid and at least one alkyl halide. The alkylhalide by reacting to at least a portion of the olefin with a hydrogen halide.
Abstract:
A process for regenerating a used acidic catalyst which has been deactivated by conjunct polymers by removing the conjunct polymers so as to increase the activity of the catalyst is disclosed. Methods for removing the conjunct polymers include hydrogenation, addition of a basic reagent and alkylation. The methods are applicable to all acidic catalysts and are described with reference to certain ionic liquid catalysts.
Abstract:
A used acidic ionic liquid catalyst, which has been deactivated by conjunct polymers, is regenerated by combining the used catalyst, a metal and a Broensted acid to hydrogenate the conjunct polymer. Regenerating a used acidic ionic liquid catalyst, which has been deactivated by conjunct polymers, includes: combining the used ionic liquid catalyst, a metal and HCI in a reaction zone under hydrogenation conditions to hydrogenate a portion of the conjunct polymer; removing reaction product from the reaction zone; mixing the removed reaction product with a hydrocarbon solvent in which the hydrogenated conjunct polymers are soluble; allowing the mixture to separate into a lighter phase which contains the hydrogenated conjunct polymers, and a heavier phase which contains a regenerated ionic liquid catalyst; and recovering at least a portion of the heavier phase is also disclosed.
