  • Patent number: 8663462
    Abstract: Methods for extracting bitumen from bituminous material through the use of a polar solvent. The method may include a primary leaching or extraction process that separates most of the bitumen from a material comprising bitumen and produces first solvent-wet tailings. A polar solvent is added to the first solvent-wet tailings in order to remove the first solvent (plus any entrained bitumen) from the tailings. A mixture of polar solvent and first solvent produced by the addition of the polar solvent to the first solvent-wet tailings may be phase separated by maintaining the polar solvent-first solvent mixture for a period of time. Alternatively, the polar solvent and first solvent may leave the tailings in a phase separated state. Phase separation may occur due to the presence of water in the polar solvent-first solvent mixture. Water may also be added to the mixture of solvents to serve as an antisolvent and initiate phase separation. The separated solvents may then be recovered and reused in the method.

    Abstract: A method for treating hydrocarbonaceous deposits to recover a petroleum-like hydrocarbon portion and a cleaned particulate substrate portion. Hydrocarbonaceous ore containing bitumen and/or kerogen is crushed or otherwise comminuted to the particle size of sand or smaller. The comminuted ore is mixed with water to form a slurry, is heated to between 60° C. and 100° C., and is blended with an oxidant in aqueous solution, preferably hydrogen peroxide. Both free interstitial hydrocarbons and those hydrocarbons bound electrostatically to the surfaces of clay-like particles in the ore are released from the rock substrate in a putative electrophysical reaction in the presence of the oxidant. Some of the released bituminous and kerogenic compounds are then controllably cleaved by the oxidant in a limited Fenton's reaction to yield organic compounds having lower average molecular weights which are suitable for refining as oil after separation from the process water phase and the residual rock substrate.

  • Patent number: 6156946
    Abstract: The present invention is a process for transforming aromatic organic compounds and resource materials. The process includes the steps of contacting an organic material selected from the group consisting of single and/or multi-ring aromatic compounds and alkylaromatic compounds, and their heteroatom-containing analogues, crude oil, petroleum, petrochemical streams, coals, shales, coal liquids, shale oils, heavy oils and bitumens with a microorganism or enzymes in order to hydroxylate the organic material, followed by contacting the hydroxylated organic resource material so as to cause hydrogenation and/or hydrogenolysis on the material.

  • Patent number: 6036849
    Abstract: A method of removing hydrocarbons from soils contaminated with various hydrocarbons such as gasoline, diesel fuel, solvents, motor oil and crude oil. The process first screens the soil to remove oversized rocks and debris and to reduce the contaminated soil to uniformly sized particles. The soil particles are moved along a conveyor and first sprayed with an oxidizer diluted with ionized water and then sprayed with only ionized water. The washed particles are then vigorously mixed with their entrained oxidizer and ionized water in an auger mixer for several minutes to oxidize almost all of the remaining hydrocarbons. The washed and hydrocarbon-free soil is then moved by conveyor to a stockpile for storage, testing and drying.

  • Patent number: 5936134
    Abstract: A method for producing synthetical oils and storable products of calorific energy, by co-processing waste rubber materials, especially waste tires, and coal optionally in the presence of a material containing Fe as a catalyst, comprising the steps of mixing triturated waste rubber material having a particle size of preferredly 1-5 mm, and coal having particle sizes of 0.2-1 mm, and, when used, the catalyst having a referred particle size of 0.05-0.015 mm, until obtaining a mixture, heating the mixture in a reactor to a temperature between 300.degree. C. and 500.degree. C., during 3-180 minutes, at a pressure between atmospheric pressure and 10 MPa, to enable a processing step basically consisting of a pyrolysis/hydropyrolysis. During the processing step, there is a generation of gases containing approximately 50% CO and CO.sub.2, and approximately another 50% by volume of C.sub.1 -C.sub.4 hydrocarbons, and having a calorific energy between 6000 and 8000 kcal/Nm.sup.

  • Patent number: 5856600
    Abstract: Described is a process for the production of depolymerized natural rubber, which makes it possible to obtain, at high reaction efficiency, of depolymerized natural rubber in the liquid form and having a narrow molecular weight distribution; and also a process for the production of depolymerized natural rubber which is free from odor or coloring peculiar to natural rubber and is also free from the danger of immediate allergy derived from protein.The process according to the present invention comprises adding a carbonyl compound to a natural rubber latex, and then subjecting the resulting natural rubber to air oxidation in the presence of a radical forming agent or adding a carbonyl compound to the latex of deproteinized natural rubber and then subjecting the deproteinized natural rubber to air oxidation optionally in the presence of a radical forming agent.

  • Patent number: 5811607
    Abstract: A process and apparatus for the recovery of hydrocarbons from hydrocarbon containing composite materials, particularly roofing materials including asphalt and solid components to recover asphalt and the solid components. The process includes the steps of: agitating the materials with a solvent, preferably a terpene, to form a hydrocarbon/solvent mixture; heating the hydrocarbon/solvent mixture to vaporize the solvent; recovering the hydrocarbons; and recovering the solvent as a liquid by condensing the solvent vapor. The apparatus includes a composite materials washer for holding the composite materials and a solvent; means for agitating the composite materials washer to dissolve the hydrocarbons in the solvent; and a separator for vaporizing the solvent in the hydrocarbon/solvent mixture and recovering the hydrocarbons.
