摘要： 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. In certain embodiments, the transfer hydrogenation process is a direct coal liquefaction process.

摘要： A deicing/anti-icing fluid includes at least 20% by weight of a freeze point depressant selected from short chain polyols having 2 to 5 carbon atoms. The fluid further includes at least 10% by weight of water, a thickener, and a surfactant. The fluid meets the requirements of SAE/AMS 1428 or its revisions for a non-Newtonian, Type II, III, or IV aircraft deicing/anti-icing fluid.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
