Abstract:
A process for regenerating a used acidic ionic liquid catalyst comprising the steps of contacting the used ionic liquid catalyst and hydrogen with a supported hydrogenation catalyst comprising a hydrogenation component on a support in a reaction zone under hydrogenation conditions for a time sufficient to increase the activity of the used catalyst is disclosed.
