Processing shale oil cuts by hydrotreating and removal of arsenic and/or selenium
Patent
·
OSTI ID:6354232
A method for processing shale oil to remove both nitrogen and impurities such as arsenic and/or selenium shile minimizing such removal costs comprises fractionating the shale oil feed to form a first naphtha cut which essentially boils at or below 350/sup 0/F and a gas oil cut which essentially boils above 350/sup 0/F, hydrotreating the first naphtha cut, separately removing a substantial amount of said impurity from the gas oil cut and then hydrotreating the gas oil cut is fractionated to form a second naphtha cut which essentially boils above 380/sup 0/F and at or below 450/sup 0/F and has a high nitrogen content, and hydrotreating the second naphtha cut to reduce the nitrogen content.
