Abstract
Disclosed herein is a highly efficient process for producing distillate fuels using a multi-bed hydrogenation reactor. The temperature of the feed to the second and subsequent reactor beds is controlled by removing effluent from the prior bed, cooling the effluent in an external heat exchanger, injecting hydrogen gas into the effluent mixture, and inserting the cooled mixture containing hydrogen gas into the inlet of the next reaction zone.
