  • Sequential hydrocracking and hydrogenating process for lube oil production
    Patent number: 4162962
    Abstract: UV-unstable hydrocrackate lube oil stock is improved by hydrogenating the stock at a temperature in the 200.degree. to 300.degree. C. range using a hydrogenating component disposed upon an alumina carrier having a substantial pore volume of which a major portion is in pores having diameters in the 80- to 150-Angstrom range.

  • Combination process for octane upgrading the low-octane C.sub.5 -C.sub.6 component of a gasoline pool
    Patent number: 4162212
    Abstract: Low-octane C.sub.5 -C.sub.6 gasoline pool mixtures or components are upgraded into improved-octane gasoline blendstock by (1) catalytically converting a minor yet significant portion of the C.sub.6 -fraction into a relatively high-octane stock using a unique crystalline aluminosilica zeolite catalyst, (2) isomerizing the C.sub.5 -fraction plus the remainder of the C.sub.6 -fraction, and (3) blending the converted C.sub.6 -portion with the C.sub.5 -C.sub.6 isomerizate.

  • Hydroprocessed shale oil including thermally treating and coking steps
    Patent number: 4142961
    Abstract: An arsenic-contaminated shale oil is thermally treated to precipitate the arsenic and to lower the pour point. Treated oil is then transported and thereafter heated to produce coke and a liquid hydrocarbon distillate. At least a portion of the distillate is catalytically processed in the presence of hydrogen, forming a treated shale oil product.
