  • Patent number: 10344236
    Abstract: The present invention relates to a process for preparing fuel-in-water emulsions from oil refining residues, in both continuously or in batches, by adding an emulsifying agent to disperse the residual oil in water and facilitate its transportation. This process does not require the use of chemical substances like stabilizers or diluents for its preparation. The vacuum residue is not limited to specific characteristics and the water used, can be distilled, tap water or saltwater (seawater). The process requires low concentration of a non-ionic surfactant; and the emulsions obtained have proportions from 70 to 90% by weight of refining residues, 10 to 30% by weight of water and from 0.1 to 1% by weight of surfactant. The fuel-in-water emulsion is produced from oil refining residues, such as residues of atmospheric and vacuum distillation, heavy fuel oils and similar, and it is formed from 70 to 90% by weight of refining residues, 10 to 30% by weight of water and from 0.1 to 1% by weight of non-ionic surfactant.

  • Patent number: 10273392
    Abstract: A sealant composition for roofing shingles that includes a base asphalt, a linear and/or a radial copolymer, oil, and a wax is provided. The linear copolymer has an A-B di-block or an A-B-A tri-block structure. The radial copolymer may have an (A-B)n radial structure, where n is at least 4, or a tri-block (A-B-A) radial structure having from 4 to 8 arms. Blocks A and B may individually represent (1) styrene and butadiene or (2) styrene and isoprene. The oil is a petroleum-based oil that both “softens” the asphalt and reduces the viscosity of the sealant composition. The wax may be a bis-stearamide wax. Additionally, the sealant composition may be reacted with elemental sulfur to crosslink the copolymer blend. The sealant composition seals at temperatures lower than conventional sealants and promotes the easy release of the shingle from a shingle bundle.

  • 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: 8901211
    Abstract: The present invention relates to a method for preparing an industrial asphalt comprising sparging an oxygen containing gas through an asphalt flux in the presence of 0.25 weight percent to about 12 weight percent of a highly saturated rubbery polymer at a temperature within the range of about 400° F. to about 550° F. for a period of time which is sufficient to increase the softening point of the asphalt flux to a value which is within the range of 185° F. to 250° F. and a penetration value of at least 15 dmm to produce the industrial asphalt. The highly saturated rubbery polymer can be a styrene-ethylene/butylene-styrene block copolymer rubber or a highly saturated styrene-ethylene/propylene-styrene block copolymer rubber.

  • Patent number: 8883887
    Abstract: A Performance Grade sulfur-extended asphalt binder emulsion is made by combining a viscosifier, an emulsifier, a Performance Grade sulfur-extended asphalt binder, optionally a saponification agent, and a base aqueous solution. During creation of the asphalt emulsion, none of the components or combinations of them exceeds 275° F. The Performance Grade sulfur-extended asphalt binder composition is made by combining free or element sulfur, a linear alkane material, optionally a saturated-backbone polymer modifier, optionally a non-aqueous acid, and a base asphalt. The disclosed Performance Graded sulfur-extended asphalt binder and Performance Graded asphalt sulfur-extended asphalt binder emulsion allow operators using these products directly or in combination with aggregates and other materials to mix and blend the compositions, and apply the compositions in the field, at temperatures less than 300° F.

  • Patent number: 8841365
    Abstract: Straight run bitumen is widely used in the production of built-structure waterproofing systems, more particularly waterproofing membranes. In order to be able to obtain supplies of straight run bitumen wherever it is obtainable at favorable prices, it would have to be transported over relatively long distances. Since straight run bitumen is viscid at ambient temperature, it would have to be transported hot, which is not possible with conventional straight run bitumen. According to the invention, the straight run bitumen is admixed with a small proportion of at least one hydrocarbonaceous polymer. This solidifies straight run bitumen at ambient temperatures, making it transportable cold in the solid state.

  • Patent number: 8808445
    Abstract: One embodiment provides a process for preparing an asphalt-coated crumb rubber composition that meets the specification set forth in ASTM D80-02 or deviations thereof which may be established by the specifying agency from time to time. The process generally comprises obtaining asphalt of different penetration grades, combining the asphalt of each grade with preselected chemicals to form separate premixed components, blending the premixed components together under predetermined conditions to form, upon curing, an asphalt-coated crumb rubber composition that meets certain physical requirements for asphalt-rubber binder (ARB), such as those set forth in ASTM D8-02. Advantageously, the resulting asphalt-coated crumb rubber composition not only meets the physical requirements of ARB used in road paving but also has improved dispersion of the rubber, such as dispersion of the rubber in an oil-in-water emulsion of an asphalt.
