  • Patent number: 4485004
    Abstract: A process is disclosed in which a heavy hydrocarbon oil is converted to lighter products by hydrocracking in the presence of a hydrogen donor material boiling from 200.degree. C. to 300.degree. C. and a particulate hydrogenation catalyst comprising one of cobalt, molybdenum, nickel, tungsten and mixtures thereof.
    Type: Grant

  • Patent number: 4294686
    Abstract: An integrated upgrading process is disclosed which can be used to lower the specific gravity, viscosity and boiling range of heavy, viscous hydrocarbonaceous oil by means of fractionally distilling the oil, treating its residuum with a hydrogen donor material under hydrocracking conditions, fractionally distilling the effluent from the hydrocracking zone and rehydrogenating that portion boiling from about 180.degree. C. to 350.degree. C. for recycling to the hydrocracking zone. The liquid portion of the oil not recycled can be recombined into a reconstituted crude suitable for transporting by normal crude pipelines.
