Abstract
A process for the hydrodesulfurization of a diesel boiling range petroleum fraction wherein the hydrodesulfurization is carried out concurrently with a fractional distillation in a distillation column reactor containing a catalyst bed. The diesel is fed above the catalyst bed and hydrogen is fed below the bed. The bottoms from the distillation column reactor is then separated by fractional distillation to remove a bottoms containing most of the unconverted sulfur.
