ABSTRACT:
A process and reactor system is disclosed for hydrotreating a low sulfur containing olefinic distillate and conventional feedstock to a catalytic hydrodesulfurization. The process comprises passing a minor portion of the olefinic distillate to a first hydrotreating zone in admixture with conventional CHD feedstock. A major portion of the olefinic distillate is passed to a second hydrotreating zone in combination with the effluent from the first zone. In this manner the exotherm attributable to olefins hydrogenation is controlled within limits sufficient to avoid very frequent catalyst regeneration.
