  • Patent number: 11319491
    Abstract: A process for making mesophase and/or isotropic pitch. An aromatic rich liquid is charged at high temperature and pressure to a first thermal polymerization reactor to produce an effluent stream which is flashed to remove unconverted or partially converted feed as a vapor yielding a liquid phase enriched in isotropic pitch. The enriched isotropic pitch liquid is charged to a second thermal reactor and reactor effluent flashed to produce mesophase pitch and a vapor phase. The vapor phases from both flashing steps are condensed and combined for recycle of a liquid aromatic rich stream to the first reactor. Flashing from the first reactor cools the liquid phase which is enriched in isotropic pitch. This enriched stream is mixed with a superheated fluid, preferably steam, upstream of the second reactor.

  • Publication number: 20150020711
    Abstract: This invention is based upon the discovery that activated carbon can be used to sequester polycyclic aromatic hydrocarbons that may be present in asphalt and creosote compositions. The treatment of asphalt and creosote compositions with activated carbon accordingly reduces the level of free polycyclic aromatic hydrocarbons in such compositions by sequestering them therein or removing them from the composition. After being sequestered the polycyclic aromatic hydrocarbons remain trapped in the asphalt or creosote composition, and are not available to the environment during normal processing into useful industrial products. This sequestration reduces the risk of exposing humans and the environment to the polycyclic aromatic hydrocarbons which would otherwise be free to migrate from the asphalt or creosote product during manufacturing and the service life of the product.

  • Patent number: 8252168
    Abstract: A method for modifying asphalt comprises blowing an oxygen-containing gas through a base asphalt at a high gas flow rate while simultaneously agitating the base asphalt at a high shear rate and at an elevated temperature for a period of time that is effective to substantially improve at least two paving properties of the base asphalt. In preferred embodiments, modified asphalts are produced having both substantially improved rutting resistance and substantially improved fatigue resistance as compared to the base asphalt.

  • Patent number: 8231775
    Abstract: A process and apparatus is disclosed for converting heavy hydrocarbon feed into lighter hydrocarbon products. The heavy hydrocarbon feed is slurried with a particulate solid material to form a heavy hydrocarbon slurry and hydrocracked in a slurry hydrocracking unit to produce vacuum gas oil (VGO) and pitch. A first vacuum column separates VGO from pitch, and a second vacuum column further separates VGO from pitch. As much as 15 wt-% of VGO can be recovered by the second vacuum column and recycled to the slurry hydrocracking unit. A pitch composition is obtained which can be made into particles and transported without sticking together.

  • Patent number: 8221105
    Abstract: Systems for pelletizing hot asphaltenes are provided. Asphaltenic hydrocarbons can be dispersed to provide two or more asphaltenic particles. The asphaltenic hydrocarbons can be at a temperature of from about 175° C. to about 430° C. The asphaltenic particles can be contacted with a film of cooling medium. The film can have a thickness of from about 1 mm to about 500 mm. At least a portion of the asphaltenic particles can be solidified by transferring heat from the asphaltenic particles to the cooling medium to provide solid asphaltenic particles. The solid asphaltenic particles can be separated from at least a portion of the cooling medium.

  • Patent number: 8197788
    Abstract: The present invention provides a raw coke having such a structure that the graphitized product resulting from graphitization of the raw coke at a temperature of 2800° C. under an inactive gas atmosphere will have ratios of the crystallite size to the lattice constant of 360 or less in the (002) plane and 1500 or less in the (110) plane, as a raw coke providing active carbon produced by alkali-activating the raw coke, which is reduced in remaining alkali content and can simplify washing operation because washing liquid can easily pass through the activated carbon, or as a raw coke for the production of needle coke.

  • Patent number: 8193401
    Abstract: Slurry hydrocracking a heavy hydrocarbon feed produces a HVGO stream and a pitch stream. At least a portion of the pitch stream is subjected to SDA to prepare a DAO stream low in metals. The DAO is blended with at least a portion of the HVGO stream to provide turbine or marine fuel with acceptable properties for combustion in gas turbines or for marine fuel grades.

  • Publication number: 20120097579
    Abstract: The present disclosure provides methods and systems for coal liquefaction and obtaining a mesophase pitch. A method of obtaining a quinolone insoluble-free and ash-free mesophase pitch may include exposing a coal to a hydrogenated vegetable oil in the presence of a coal-derived solvent to form a slurry, elevating the temperature of the slurry to facilitate liquefying the coal and liberating a volatile matter, separating the insoluble components from the slurry to obtain a de-ashed coal extract that is quinoline insoluble-free, and distilling the coal extract under vacuum to obtain a mesophase pitch with a softening point in the range of 25 degrees Celsius to 160 degrees Celsius, wherein the mesophase pitch can be coked to obtain an anisotropic coke.

  • Patent number: 8092671
    Abstract: A method is disclosed for treating gaseous effluent from a hydrocarbon pyrolysis unit to provide steam cracked tar of reduced asphaltene and toluene insolubles content. The method is suitable for preparing reduced viscosity tar useful as a fuel blending stock, or feedstock for producing carbon black, while reducing or eliminating the need for externally sourced lighter aromatics additives to meet viscosity specifications. The method comprises drawing steam cracked tar from a separation vessel, e.g., a primary fractionator or tar knock-out drum, cooling the tar, and returning it to the separation vessel to effect lower overall tar temperatures within the separation vessel, in order to reduce viscosity increasing condensation reactions. An apparatus for carrying out the method is also provided.
