Abstract:
A process for regenerating a used acidic ionic liquid catalyst which has been deactivated by conjunct polymers comprising combining the used catalyst, a metal and a Broensted acid which acts a source of hydrogen in a reaction zone under hydrogenation conditions for a time sufficient to hydrogenate at least a portion of the conjunct polymer is disclosed.
