N2 - The effects of the removal extents of nitrogen containing species in gas oil on its deep hydrodesulfurization (HDS) was studied by using conventional catalyst and reaction conditions. The 80% denitrogenated gas oil achieved the total sulfur content of 19ppmS by hydrotreating at 340°C while the feed and 64% denitrogenated gas oils resulted in 311 and 120ppmS of total sulfur contents, respectively under the same conditions. Selective removal of refractory sulfur species which occurred simultaneously with nitrogen removal over a proprietary adsorbent was recognized very effective to achieve deep HDS.
