摘要：
A process for regenerating a used acidic ionic liquid catalyst which has, been deactivated comprising the steps of contacting the used chloroaluminate ionic liquid catalyst and hydrogen with a metal hydrogenation catalyst in a reaction zone under hydrogenation conditions for a time sufficient to increase the activity of the ionic liquid catalyst is described. In one embodiment, hydrogenation is conducted in the presence of a hydrocarbon solvent.
