  • Patent number: 11623990
    Abstract: Asphalt binders are modified using fractional products from waste tire pyrolysis, using an initial step of i) at least partially pyrolyzing, separately from such asphaltic binder, whole rubber articles or size-reduced rubber particles to provide one or more pyrolyzed rubber fractions including a pyrolyzed oil fraction having a selected minimum initial boiling point or flash point, and ii) removing some or all polycyclic aromatic hydrocarbon (PAH) compounds from such pyrolyzed oil fraction to provide a reduced-PAH and preferably translucent pyrolyzed oil fraction that may be combined with an asphaltic binder to provide a modified asphalt composition.

  • Patent number: 11566187
    Abstract: Naphthenic process oils are made by blending one or more naphthenic vacuum gas oils in one or more viscosity ranges with a high CA content distilled aromatic extract feedstock to provide at least one blended oil, and hydrotreating the at least one blended oil to provide an enhanced CA content naphthenic process oil.

  • Patent number: 6569351
    Abstract: The present invention is directed to a an accelerator-gel additive used to deliver an accelerator such as sulfur, into a system for the production of polymer modified asphalt, vulcanized rubber or similar system. Unlike conventional methods of delivering accelerator into the system, the accelerator-gel additive suspends the accelerator in a gel system thereby preventing the sedimentation of the accelerator during processing. As a result, the polymer and asphalt are processed at lower temperature reducing the production of toxic and flammable gases such as hydrogen sulfide.

  • Patent number: 4905918
    Abstract: Pulverizer apparatus is provided for pulverizing solid materials into very fine particles. A cylindrical shell member within the pulverizer housing devides the interior of the housing into central and outer chambers therebetween. A cap disposed above a frusto-conical upper portion of the shell includes a bottom portion closing off the top of the shell and a downwardly depending frusto-conical portion. The latter is mounted in spaced, at least partially overlapping relationship with the upper portion of the shell so as to define a downwardly inclined passageway which opens into the outer chamber. A nozzle assembly, located near the bottom of the housing, produces a plurality of jets of air directed radially inwardly towards the center of the central chamber at an angle such that particles of a material located at the bottom of the central chamber are caused to rise and to impact upon each other so as to provide pulverization thereof.

  • Patent number: 4412839
    Abstract: A process and apparatus for treating coal to produce micron-size coal particles having high surface reactivity and a low level of ash-forming impurities. The process involves grinding the coal in a substantially air tight fluid energy attrition mill under controlled temperature conditions to form a coal fraction comprising a major portion of hydrophobic coal particles and a minor portion of hydrophilic coal particles and an impurities-fraction comprising hydrophilic impurities particles, and separating the hydrophobic coal particles from the hydrophilic particles by virtue of the particles' relative affinity for water. The relative amount of hydrophilic coal particles may be reduced by the addition of a petroleum fraction to the coal during grinding.

  • Patent number: 4394132
    Abstract: Improved particulate coal-in-liquid mixtures and a process for the production thereof wherein, prior to mixing with liquid, the coal component of the mixture is finally divided in a substantially airtight fluid energy attrition mill, and thereafter separated from ash particles. The particulate coal product thus produced is mixed with a suitable liquid to provide a product which may be used in coal gasification or hydrogenation processes, or as a composite fuel, and which can be stored for extended periods without appreciable settling out of the coal from the mixture.
