  • Patent number: 10113122
    Abstract: The present disclosure provides a process that employs glycerol and a catalyst for partial transformation of heavy petroleum oils to lighter hydrocarbon liquids under mild conditions without the need of external hydrogen gas. The process uses industrially produced glycerol to upgrade heavy crudes; hydrogenates aromatics to paraffin and/or olefins without the use of external hydrogen gas; operates at mild operating conditions; and employs inexpensive catalysts. This process is completely different from the hydroconversion process where high pressurized hydrogen gas is essential. The present process requires no pressurized hydrogen gas and can significantly reduce both operating and capital costs of the traditional hydrotreating process.

Introducing at least a portion of the reactive gas as a radial flow stream allows the reactive gas to travel through the catalyst bed along a shorter path length. This reduces the pressure drop for the radial flow portion of the gas. The reactive gas can be introduced into the catalyst bed at various heights relative to the height of the catalyst bed.

  • Patent number: 9375700
    Abstract: An aspect of at least one embodiment of the present invention is a device for cracking heavy hydrocarbons. A linear applicator is positioned within heavy oil containing aromatic molecules. A radio frequency electrical current source is electrically connected to the applicator at a first connection point and a second connection point to create a closed electrical loop. The radio frequency source is configured to apply a signal to the applicator that is sufficient to create a magnetic field and an electric field relative to the axis of the linear applicator. The device also includes a chamber positioned around the applicator generally between the first connection point and the second connection point to concentrate the magnetic field within a region surrounding the applicator and containing the heavy hydrocarbons.

  • Patent number: 9365781
    Abstract: A process of hydroprocessing a hydrocarbon in a down flow reactor comprising one or more hydroprocessing-catalyst beds. The hydrocarbon feed is mixed with hydrogen and optionally diluent to form a liquid feed mixture wherein hydrogen is dissolved in the mixture, and the liquid feed mixture is introduced into the down flow reactor under hydroprocessing conditions. The hydroprocessing-catalyst bed(s) are liquid-full and the feed reacts by contact with the catalyst. Hydrogen gas is injected into at least one of the hydroprocessing-catalyst beds such that at least part of the hydrogen consumed in that bed is replenished and the liquid-full condition is maintained. In a multi-bed reactor, hydrogen gas may be injected into more than one or all of the hydroprocessing-catalyst beds.

  • Patent number: 9290705
    Abstract: In an FCC process and system, a whole crude oil feedstock is directly converted into light olefins and other products. The feed is separated into a high boiling fraction and a low boiling fraction, and each fraction is processed in separate FCC downflow reactors. The catalyst, combined from both downflow reactors, is regenerated in a common vessel. The low carbon content in the catalyst particles from the low boiling fraction downflow reactor is insufficient to provide the necessary heat. By combining catalyst particles from the high boiling fraction having high carbon content helps to provide additional heat for regeneration.

  • Patent number: 9212313
    Abstract: Methods, processes, apparatus, systems, and compositions are disclosed for improving the sustainability of oil sands processing. In some embodiments, bitumen is combined with biodiluent comprising one or more liquid pyrolysis fractions obtained from pyrolyzing biomass and collecting multiple liquid fractions. The bitumen may be any source of bitumen, such as bitumen obtained from oil sands. In some embodiments, a water-rich pyrolysis liquid displaces water use in an oil sands process. The water-rich pyrolysis liquid may be used for primary separation of bitumen from oil sands or for hydrotransport, for example. Also, biochar produced from biomass pyrolysis may be introduced to an oil sands tailing pond with various benefits. Water may be recycled from a tailing pond. Integration of a pyrolysis and separation process into an oil sands refining process reduces the overall greenhouse-gas emissions on a well-to-refined product basis by 10-70% or more. Various compositions and products are also disclosed.
