1. A method for regenerating deactivated acidic catalyst containing conjunct polymer comprising:
contacting the deactivated acidic catalyst containing the conjunct polymer with at least one C1 to C10 paraffin in a regeneration zone under regeneration conditions, the acidic catalyst selected from the group consisting of sulfuric acid, hydrofluoric acid, trifluoromethanesulfonic acid, phosphoric acid, boron trifluoride, and acidic ionic liquids, the conjunct polymer reacting with the at least one C1 to C10 paraffin, resulting in a mixture comprising regenerated acidic catalyst, the reacted C1 to C10 paraffin, and the released conjunct polymer; and separating the released conjunct polymer from the regenerated acidic catalyst.
