摘要： The GreenBox+ technology is suitable to extract hemicellulose sugars prior to pulping of biomass into pulp products. The revenue obtainable from the sugar stream can significantly improve the economics of a pulp and paper mill. An initial extraction and recovery of sugars is followed by production of a pulp product with similar or better properties. Other co-products such as acetates and furfural are also possible. Some variations provide a process for co-producing pulp and hemicellulosic sugars from biomass, comprising: digesting the biomass in the presence of steam and/or hot water to extract hemicellulose into a liquid phase; washing the extracted solids, thereby generating a liquid wash filtrate and washed solids; separating the liquid wash filtrate from the washed solids; refining the washed solids at a refining pH of about 4 or higher, thereby generating pulp; and hydrolyzing the hemicellulose to generate hemicellulosic fermentable sugars.

摘要： Embodiments of the present invention overcome the well-known recalcitrance of lignocellulosic biomass in an economically viable manner. A process and a system are provided for the efficient fractionation of lignocellulosic biomass into cellulose, hemicellulose, and lignin. The cellulose and hemicellulose thus obtained are highly amorphous and can be readily converted into highly concentrated mixtures of five and six carbon sugars using known methods. Typical yields of sugars exceed 100 grams of sugars per liter of sugar solution. Other products, such as alcohols, can easily be prepared according to methods of the invention. The modest process conditions and low solvent/solid ratios of some embodiments of the invention require relatively low capital and processing costs.

摘要： A flow wood processing extracting lignin from woody plant material and converting delignified cellulosic residue to crude bio-oils, that removes toxic preservative chemicals from waste timber, and provides conversion to useful or nontoxic forms. Wood is chipped and fed into a lignin extractor using ethanol at high temperatures to dissolve the lignin with counter current material contactors, heat exchangers, and a computer control system. Most of preservative chemicals likely precipitate out at this stage as a heavy sludge that can be removed. Ethanol containing dissolved lignin is removed from the lignin extractor, the dissolved lignin recovered, the ethanol recycled into the lignin extractor, and residual heat returned to the process. Delignified cellulosic pulp is removed from the lignin extractor and subjected to a milling to convert into a smooth sludge for entry to a bio-convertor by a super critical water process. The residue is prepared as a high phosphate fertilizer.

摘要： A method for measuring and controlling a chip level and/or a chip-liquor combination level and/or liquor level height of a liquid-steam phase digester or a hydraulic digester which digester comprises a chip screw for feeding chips into a digesting volume. The method comprises mounting electrode pairs in certain heights and vertically at distances from each other in the digesting volume of the digester, the electrode pairs being formed of electrodes; connecting the electrode pairs to electric circuits; measuring in each electric circuit a current or voltage value during operation of the digester; determining, based on the measurement, type of material layer (for example, steam, chips, combination of chips and liquor, or liquor) located in a certain height, based on the electrical conductivity of the materials in the digesting volume. An arrangement for measuring and controlling a chip level and/or a chip-liquor combination level and/or a liquor level height of a liquid-steam phase digester or a hydraulic digester.
