Abstract: A method of depolymerizing coal includes preparing a high temperature depolymerizing medium consisting of heavy hydrocarbon oils and mixing it with coal to form a mixture, performing an optional first distillation at a temperature below 250° C. to recover naphthalene, heating the mixture to a temperature between 350° C. and 450° C. to create a digested coal, centrifuging the digested coal to remove ash and obtain a centrate, and distillation of the centrate into separate fractions. The high temperature depolymerizing medium may be a heavy hydrocarbon with a hydrogen to carbon (H/C) ratio higher than 7.0% and may include liquids chosen from the group consisting of: coal tar distillate, decant oil, anthracene oil, and heavy aromatic oils. The high temperature depolymerizing medium may be blended with an oil, preferably with H/C ratio higher than 10.0%, such as soybean oil, other biomass derived oil, lignin, petroleum oil, pyrolysis oil such that the overall hydrogen-to-carbon mass ratio in a digestion reactor is over 7.0% for the mixture of depolymerizing medium and coal. The depolymerized coal is an aromatic liquid that can itself be, either wholly or in part, a depolymerizing medium so that the process can be repeated.

Abstract: Processing of a reaction product mixture containing at least one volatile organic compound as well as lignin, lignin derived compounds, and/or unextracted cellulose and hemicellulose using a recovery system comprising at least two flashers or at least one flasher and at least two reboilers. In a particular embodiment, the reaction product mixture comes from reactions involving deconstruction (or digestion) of biomass, particularly cellulosic biomass which contains various polysaccharides (e.g., carbohydrates) and lignin.

Abstract: Digestion of cellulosic biomass solids may be complicated by release of lignin therefrom. Methods and systems for processing a reaction product containing lignin-derived products, such as phenolics, can comprise hydrotreating the reaction product to convert the lignin-derived products to desired higher molecular weight compounds. The methods can further include separating the higher molecular weight compounds from unconverted products, such as unconverted phenolics, and recycling the unconverted phenolics for use as at least a portion of the digestion solvent and for further conversion to desired higher molecular weight compounds with additional hydrotreatment. The methods and systems can further include generating hydrogen with the further hydrotreatment.

Abstract: Polycarbon biofuels may be made from feedstock such as wood waste, agricultural wastes and waste paper. The feedstock may be cooked under acidic conditions to convert cellulose and similar material in the feedstock into a biofuel that is hydrophobic, readily pelletized, and has a high energy density. The biofuel may be blended with coal or other fuels to provide blended fuels that may be burned in conventional burners. One process forms a slurry of the feedstock, sparges carbon dioxide through the slurry to achieve a pH below 5 and cooks the slurry at temperatures in the range of 170 C to 300 C until conversion of the feedstock to polycarbon biofuel has occurred. The biofuel may be separated from liquids in the slurry by filtration.

Abstract: The amount of renewable hydrocarbons produced from biomass may be increased by pyrolyzing the biomass in a biomass conversion unit in the presence of hydrogen sulfide or a sulfiding agent. The formation of deposits of unwanted carbonaceous materials, such as coke, is reduced by the presence of the hydrogen sulfide or sulfiding agent.

Abstract: A method for converting hydrocarbon materials into a product includes receiving a hydrocarbon feedstock in a first reaction chamber, receiving a process gas in the first reaction chamber, and forming a first set of discharge conditions in the presence of energy from a microwave generator, in the first reaction chamber, to convert the hydrocarbon feedstock into an intermediate product for delivery to a second reaction chamber. The method also includes delivering the intermediate product to the second reaction chamber, forming a second set of discharge conditions, and converting the intermediate product into a final product in the second reaction chamber.

Abstract: A selective removal of chlorine and phosphorus that are detrimental to subsequent hydrothermal hydrocatalytic conversion from the biomass feed prior to carrying out catalytic hydrogenation/hydrogenolysis/hydrodeoxygenation of the biomass in a manner that does not reduce the effectiveness of the hydrothermal hydrocatalytic treatment while minimizing the amount of water used in the process is provided.
