Patent number: 11560519Abstract: Processes for converting the coal-derived heavy-oil fraction of syncrude to polyols are described. The processes involve mixing a feed stream comprising the coal-derived heavy-oil fraction with an alcohol and aqueous sulfuric acid, heating the mixture, reacting the coal-derived heavy-oil fraction with ozone, and reacting the ozonated heavy-oil fraction with glycerin to form the polyol. In some cases, the ozonated heavy-oil fraction can be neutralized before reacting the ozonated heavy-oil fraction with the glycerin.Type: GrantFiled: March 9, 2022Date of Patent: January 24, 2023Assignee: Battelle Memorial InstituteInventors: Satya P. Chauhan, Daniel B. Garbark

Patent number: 11466217Abstract: 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.Type: GrantFiled: September 19, 2016Date of Patent: October 11, 2022Assignee: Battelle Memorial InstituteInventors: Satya P. Chauhan, Daniel B. Garbark, Herman P. Benecke, H. Nicholas Conkle

Patent number: 10494270Abstract: 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.Type: GrantFiled: April 7, 2017Date of Patent: December 3, 2019Assignee: Winner Water Services, Inc.Inventors: Bruce F. Monzyk, F.

Patent number: 8222223Abstract: 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.Type: GrantFiled: September 7, 2010Date of Patent: July 17, 2012Assignee: Battelle Memorial InstituteInventors: Satya P.
