Abstract: A method for regenerating deactivated acidic ionic liquid is described. The method involves reducing a level of free hydrochloric acid in the deactivated acidic ionic liquid in a removal zone using at least one of heat, a stripping fluid, reduced pressure, and liquid-liquid extraction to form a deactivated acidic ionic liquid having a reduced level of free hydrochloric acid; and regenerating the deactivated acidic ionic liquid having the reduced level of free hydrochloric acid.

Abstract: A hydrocarbon conversion process is described. The process includes contacting a hydrocarbon feed with an acidic catalyst under hydrocarbon conversion conditions in a hydrocarbon conversion zone. The hydrocarbon feed reacts to form a mixture comprising reaction products, the acidic catalyst, and deactivated acidic catalyst containing conjunct polymer. The mixture is separated into at least two streams, a first stream comprising the reaction products and a second stream comprising the deactivated acidic catalyst. The reaction products are recovered. The deactivated acidic catalyst is contacted with at least one silane or borane compound in a regeneration zone under regeneration conditions, the conjunct polymer reacting with the at least one silane or borane compound resulting in a catalyst phase and an organic phase containing the conjunct polymer and at least one silyl or boryl compound.

Abstract: A method of regenerating an acidic catalyst is described. A borane compound is contacted with an acidic catalyst that contains conjunct polymer, which releases the conjunct polymer from the acidic catalyst. The acidic catalyst can then be re-activated with acid. The conjunct polymer can be separated from the borane compound, and the borane compound can be recycled.
