  • Maximizing jet fuel from shale oil
    Patent number: 4342641
    Abstract: Improved method for maximizing jet fuel from shale oil involves hydrotreating the treated oil at a temperature of about 600.degree.-650.degree. 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.degree. F. in the presence of a catalyst having a relatively high metal content. A 480.degree. F. minus boiling point fraction fractionated from the foregoing process can meet JP-4 jet fuel specifications. Hydrocracking the 480.degree. F. plus boiling point fraction results in substantial additional quantities of jet fuel.

  • Shale oil process
    Patent number: 4338186
    Abstract: A process for converting the raffinate from an HCl-treated shale oil to a suitable feedstock for a hydrocracking reactor for making fuels from the raffinate by hydrotreating the raffinate and thereafter water quenching the hydrotreated product.
