The present disclosure provides systems and methods for regenerating a hydrogenation catalyst with reduced water consumption and/or shortened overall regeneration time. The method can include contacting a fouled hydrogenation catalyst with a first flushing medium comprising water and a gaseous phase comprising oxygen and optionally a second flushing medium comprising water and a gaseous phase comprising at least 90% nitrogen by volume. The method can further include treating the effluents of the flushing mediums by ion exchange resin to remove impurities in the effluents.
