  • Publication number: 20200270530
    Abstract: Processes for treating highly viscous hydrocarbons, such as bitumen from oil sands or petroleum residues, with hydrogen-donor solvents are described. The hydrogen-donor solvent is prepared. A mixture of the hydrocarbon and the hydrogen-donor solvent is heated, and the product is cooled to produce a low viscosity and mildly upgraded hydrocarbon. The hydrogen-donor solvent can be modified to improve its solvent usefulness.

  • Publication number: 20200231879
    Abstract: A process of producing a distillate fuel from lignin includes: preparing a biomass-derived lignin solvent; dissolving the lignin in the biomass-derived solvent; and separating undissolved lignin and mineral matter to produce a syncrude. In certain embodiments, the process further includes subjecting the syncrude to a hydrotreatment/hydrogenation process to produce a distillate fuel. A process to improve direct lignin liquefaction includes: using a non-hydrogenated lipid in a direct lignin liquefaction process to facilitate lignin depolymerization. A process for using a biomass-derived feedstock as a hydrogen donor includes: providing a biomass-derived feedstock; modifying the feedstock to improve its usefulness as a hydrogen donor; and conducting a transfer hydrogenation process using the modified feedstock as a hydrogen donor.

  • Patent number: 10494270
    Abstract: The invention provides an efficient method to purify an aqueous solution, typically mine drainage water, especially of anions and cations present in the aqueous solution as dissolved solids, the anions and cations are removed by treatment with a positively charged extractant having at least eight carbon atoms, whereby an unstable emulsion is formed; the unstable emulsion is allowed to break into an extract phase loaded with the anions and cations, and a water phase depleted in anions and cations; a floc inherently forms in the loaded extractant phase and then the loaded extractant phase and floc are separated from the purified water and treated to remove the anions and cations as concentrated useful products; the treated aqueous phase now reduced in anion and/or cation content is also separated from the emulsion as a purified aqueous solution. The extractant phase is preferably recycled. A continuous water purification process is provided.

  • Publication number: 20190153328
    Abstract: A process of producing a distillate fuel from coal includes: preparing a biomass-derived coal solvent; dissolving the coal in the biomass-derived solvent; and separating undissolved coal and mineral matter to produce a syncrude. In certain embodiments, the process further includes subjecting the syncrude to a hydrotreatment/hydrogenation process to produce a distillate fuel. In certain embodiments, the biomass-derived solvent is a hydrogen-donor solvent. A method to improve direct coal liquefaction includes: using a non-hydrogenated lipid in a direct coal liquefaction process to facilitate coal depolymerization. In certain embodiments, the lipid is a polyunsaturated biobased oil. A method for using a biomass-derived feedstock as a hydrogen donor includes: providing a biomass-derived feedstock; modifying the feedstock to improve its usefulness as a hydrogen donor; and conducting a transfer hydrogenation process using the modified feedstock as a hydrogen donor.

  • Patent number: 8222223
    Abstract: A method of treating biocells includes the steps of: a. providing biocells; b. applying at least one stressor to the biocells sufficient to cause nonlethal and reparable cell wall damage to the biocells, thereby putting the biocells in a catabolic state during which catabolic metabolic functions predominate over anabolic metabolic functions; and c. obtaining at least one product produced by the biocells during the catabolic state. In another embodiment, the method includes the steps of: a. providing biocells that are mammalian cells; b. applying at least one stressor to the biocells sufficient to cause nonlethal and reparable cell wall damage to the biocells, the reparable cell wall damage comprising openings that allow increased passage of materials through the cells walls; and c. inserting foreign DNA through the openings into the biocells.

  • Publication number: 20100108588
    Abstract: A method of converting biological material into energy resources includes transmitting biological material to a pulsed electric field (PEF) station, and applying a PEF to the biological material within a treatment zone in the PEF station to generate treated biological material. The method also includes transmitting the treated biological material to a biogenerator, and processing the treated biological material in the biogenerator to produce an energy resource. A converter may carry out this process, and may include the PEF station and the biogenerator.
