Abstract
A process for oligomerizing and oligomerizing olefins to distillate fuels which regenerates a first stage oligomerization catalyst bed and/or a second oligomerization catalyst bed in situ by contact with an oxygen gas at elevated temperature. The oligomerization catalyst can be restored to full activity. A regeneration process can enable continuous operation.
