  • Patent number: 9090773
    Abstract: A method of producing sulfur modified organosilane compounds that can be used in asphalt binders which method involves: combining together an organosilane or mixtures of organosilanes, a sulfide, a halogen acceptor and solvent to form a reaction mixture; and allowing the organosilane to react with the sulfide in the presence of a halogen acceptor to produce a sulfur modified organosilane compound. The sulfur modified organosilane compound can be introduced into a polymer modified or unmodified asphalt binder in which the sulfur modified organosilane compound reacts with components in the asphalt mixture to form a modified asphalt. The organosilanes used to produce the sulfur modified organosilanes can be from a source of waste products (such as Direct Product Residue) in which case the waste products can be reused in asphalt binders.

  • Patent number: 8945351
    Abstract: A method of removing organic components from a mixture containing organic and inorganic components which method involves providing an induction heated screw conveyor having an auger and passing the mixture through the induction heated screw conveyor while inductively heating the auger so as to heat the mixture in the induction heated screw conveyor primarily from the center of the induction heated screw conveyor. The mixture is heated to a temperature that is sufficient to cause the organic components in the mixture to separate from the mixture as a vapor. The oxygen concentration in the induction heated screw conveyor is controlled so as to gasify the organic components. The gasified organic components are removed and the remaining inorganic components are collected.

  • Patent number: 8945350
    Abstract: A method of separating a high boiling component from a mixture containing organic and/or inorganic boiling components which method involves providing an induction heated screw conveyor having an auger and passing the mixture through the induction heated screw conveyor while inductively heating the auger so as to heat the mixture in the induction heated screw conveyor. The mixture is heated to a temperature that is sufficient to cause the boiling component(s) to separate from the mixture as a vapor and the boiling component is removed from the induction heated screw conveyor.

  • Patent number: 8344036
    Abstract: A method of processing polymer materials, highly filled or otherwise to recover cyclic structures or monomers. The method involves providing a vessel having a heated side wall, an agitator, and at least one of an additional heated structure, other than the heated side wall, within the vessel and means for forming a thin coat of material processed in the vessel on said heated side wall. A polymer material is fed into the vessel and heated to a sufficient temperature to cause depolymerization of the polymer material into cyclic structures or monomers. The cyclic structures or monomers are removed from the vessel and collected. The method does not require the use of a solvent.
