Maximizing jet fuel from shale oil

Improved method for maximizing jet fuel from shale oil involves hydrotreating the treated oil at a temperature of about 600 DEG -650 DEG F. in the presence of a catalyst having a relatively low metal content and then hydrotreating the oil at a temperature in excess of about 800 DEG F. in the presenc...

Zusammenfassung:	Improved method for maximizing jet fuel from shale oil involves hydrotreating the treated oil at a temperature of about 600 DEG -650 DEG F. in the presence of a catalyst having a relatively low metal content and then hydrotreating the oil at a temperature in excess of about 800 DEG F. in the presence of a catalyst having a relatively high metal content. A 480 DEG F. minus boiling point fraction fractionated from the foregoing process can meet JP-4 jet fuel specifications. Hydrocracking the 480 DEG F. plus boiling point fraction results in substantial additional quantities of jet fuel.
