    Abstract: An improved hydrocarbon cracking process includes a first reactor such as a nozzle reactor positioned in series with a second reactor such as a tubular reactor. A cracking fluid such as steam or natural gas is reacted with heavy hydrocarbon material in the first reactor. The first reactor may provide a tremendous amount of thermal and kinetic energy that initiates cracking of heavy hydrocarbon materials. The second reactor provides sufficient residence time at high temperature to increase the conversion of heavy hydrocarbon materials to the desired level. The cracking fluid functions as a hydrogen donor in the cracking reactions so that very little of the heavy hydrocarbon material becomes hydrogen depleted and forms coke even if the heavy hydrocarbon material is repeatedly recycled through the process.

  • Patent number: 7976695
    Abstract: Methods and apparatus are disclosed for possibly producing pipeline-ready heavy oil from substantially non-pumpable oil feeds. The methods and apparatus may be designed to produce such pipeline-ready heavy oils in the production field. Such methods and apparatus may involve thermal soaking of liquid hydrocarbonaceous inputs in thermal environments (2) to generate, though chemical reaction, an increased distillate amount as compared with conventional boiling technologies.

  • Publication number: 20110162999
    Abstract: Methods, systems and other embodiments associated with upgrading heavy oil with modular units are presented. A method of upgrading heavy oil with modular units comprises connecting modular units together to create a heavy oil refinery system. The method upgrades original heavy oil in the refinery system by creating high pressure pulses in heavy oil to crack the heated heavy oil to produce a processed oil with a lower viscosity than the original heavy oil.

  • Patent number: 7968757
    Abstract: A process for hydrocracking biomass, and the hydrocarbons produced therefrom. A feed stream having free fatty acids, fatty acid esters, or combinations thereof is contacted with a first catalyst under hydrogen pressure and heat. The hydrocarbon product stream which is comprised predominantly of n-paraffins is separated into heavy and light fractions. The heavy fraction is contacted with a second catalyst under hydrogen pressure and heat to produce an effluent stream which is combined with the light n-paraffin fraction to form a unique middle distillate product useful as a diesel or jet fuel.

  • Publication number: 20110147264
    Abstract: Systems and processes for the hydroprocessing of a hydrocarbonaceous feed are provided that utilize a plurality of moving bed reactors. The reactors may be moving bed radial flow reactors. A hydrogen injection point can be provided prior to each reactor by providing a mixer that mixes hydrogen with a hydrocarbonaceous feed, or with the effluent stream from an upstream reactor, to produce a reactor feed stream. Catalyst can be provided from the reaction zone of one reactor to the reaction zone of a downstream reactor through catalyst transfer pipes, and can be regenerated after passing through the reaction zones of the reactors. The moving bed reactors can be stacked in one or more reactor stacks.
