A process for hydrodenitrogenation of shale oil comprising fractionating the shale oil into relatively light and heavy fractions, passing the relatively light fraction through a zone containing a catalyst comprising supported molybdenum and Group VIII metal and passing the relatively heavy fraction

A process for hydrodenitrogenation of shale oil comprising fractionating the shale oil into relatively light and heavy fractions, passing the relatively light fraction through a zone containing a catalyst comprising supported molybdenum and Group VIII metal and passing the relatively heavy fraction through a zone containing a catalyst comprising supported tungsten and Group VIII metal.

A process for the hydrodenitrogenation of shale oil comprising passing a feed shale oil to a distillation zone, removing a relatively low boiling fraction and a relatively high boiling fraction from said distillation zone, passing said low boiling fraction and hydrogen through a zone containing a first catalyst comprising molybdenum as the major supported metallic component in an amount between about 1 and 15 weight percent together with between about 1 to 10 weight percent of Group VIII metal on a non-cracking support, not more than 20 weight percent of said low boiling fraction boiling above the naphtha range being converted to material boiling in or below said naphtha range, passing said high boiling fraction and hydrogen through a zone containing a second catalyst comprising tungsten in an amount between 1 and 25 weight percent together with between about 1 and 25 weight percent of Group VIII metal on a non-cracking supporting material, the temperature in said zones being between about 650°and 800°F. and the hydrogen pressure in said zones between about 500 and 5,000 psi.
