  • Patent number: 10519385
    Abstract: Spent zeolite equilibrium catalyst from the fluidized catalytic cracker has a useful function as an adsorbent for jet fuel. Redirecting such spent catalyst saves costs for refinery operations in two ways. The first is by avoiding the costs for disposing of such catalyst as hazardous waste. The second is to reduce the cost of procuring sorbent for the jet fuel decontamination process. Since zeolite is primarily silica and conventional sorbents are also silica, zeolite catalysts are chemically similar. And the equilibrium catalyst may be regenerated in the FCC after its becomes saturated with jet fuel contaminants and re-used.

  • Patent number: 10450518
    Abstract: A supercritical water separation process and system is disclosed for the removal of metals, minerals, particulate, asphaltenes, and resins from a contaminated organic material. The present invention takes advantage of the physical and chemical properties of supercritical water to effect the desired separation of contaminants from organic materials and permit scale-up. At a temperature and pressure above the critical point of water (374° C., 22.1 MPa), nonpolar organic compounds become miscible in supercritical water (SCW) and polar compounds and asphaltenes become immiscible. The process and system disclosed continuously separates immiscible contaminants and solids from the supercritical water and clean oil product solution. The present invention creates a density gradient that enables over 95% recovery of clean oil and over 99% reduction of contaminants such as asphaltenes and particulate matter depending on the properties of the contaminated organic material.

  • Patent number: 8968557
    Abstract: The present invention provides a method of converting coal to a petroleum product. The method includes the steps of mixing the coal and water to form a mixture, and heating the mixture to approximately 500 degrees Fahrenheit. The method further includes separating the mixture in a first separator into a liquid stream of a water bearing minerals and a solid stream of coal, and transferring the coal from the first separator to a coking reactor wherein the temperature is raised to approximately 1,000 degrees Fahrenheit to drive off lighter fractions of the coal as a gas. The method also includes transferring the gas to a fourth separator to separate water and liquid petroleum product from the gas.

  • Patent number: 8951407
    Abstract: A simplified process is provided for creating hybrid crude oils and hybrid crude fractions with characteristics superior to the original. The process uniquely combines gases with crude oil or crude fractions in an effervescent turbulent manner at low temperatures and pressures and without the further aid of catalysts. The process breaks large chain hydrocarbons into smaller chain hydrocarbons, molecularly combines carbon, hydrogen, and/or hydrocarbon molecules from the gases with and into hydrocarbon molecules of the crude or crude fraction, and separates contaminants and impurities.

  • Patent number: 8927796
    Abstract: This invention discloses a process for making high viscosity index lubricating base oils having a viscosity index of at least 110 by co-feeding a ketone or a beta-keto-ester feedstock with a lubricant oil feedstock directly to a hydrocracking unit to produce a hydrocracked stream. Then at least a portion of the hydrocracked stream is treated under hydroisomerization conditions to produce a high viscosity index lubricating base oil. The process may involve bypassing a hydrotreating or hydrofinishing step, which may result in improved efficiency and economics in producing high viscosity index lubricating base oils.

  • Patent number: 8920634
    Abstract: Methods and systems relate to treating an oil-in-water emulsion with an electron beam to decrease aromatic content therein for subsequent recovery of diesel products with upgraded cetane number. The method includes passing the emulsion formed of water and a hydrocarbon stream, such as light cycle oil, through an electron beam. The electron beam causes radiolysis of the water into intermediates that react with and open rings of aromatic compounds from the hydrocarbon stream. Separation of the water from the emulsion after the treating with the electron beam provides the diesel products, which may be hydroprocessed to remove oxygenates.

  • Publication number: 20140353207
    Abstract: Conversion of heavy fossil hydrocarbons (HFH) to a variety of value-added chemicals and/or fuels can be enhanced using microwave (MW) and/or radio-frequency (RF) energy. Variations of reactants, process parameters, and reactor design can significantly influence the relative distribution of chemicals and fuels generated as the product. In one example, a system for flash microwave conversion of HFH includes a source concentrating microwave or RF energy in a reaction zone having a pressure greater than 0.9 atm, a continuous feed having HFH and a process gas passing through the reaction zone, a HFH-to-liquids catalyst contacting the HFH in at least the reaction zone, and dielectric discharges within the reaction zone. The HFH and the catalyst have a residence time in the reaction zone of less than 30 seconds. In some instances, a plasma can form in or near the reaction zone.
