    Abstract: In order to recover inorganic chemicals from waste liquors in cellulose manufacturing processes it is proposed to separate the alkali or alkaline earth from the organic components by partial or complete oxidation in the aqueous phase with air and/or oxygen. Before this oxidation process, it is possible to separate the lignin in the black liquor by acidification and precipitation with a mineral acid, the resins by extraction and the demi-celluloses by ultra-filtration, whereupon the residual organic substances still remaining in solution are oxidised. Wet oxidation is possible such that the carboxylic acids, especially the acetic acid, is not burned as well and can be separated by crystallisation after caustification. The chemical solution thus freed of organic substances can be returned to the liquor by caustification and made available in the cellulose production cycle.

    Abstract: In a process for manufacturing chemo-mechanical and/or chemo-thermo-mechanical wood pulps, raw materials containing lignocellulose, such as wood shavings, wood chips, pre-ground wood or sawdust, are first impregnated with an aqueous alcoholic SO2 solution and then heated to a temperature between 50 and 170 °C for a period of 1 to 300 minutes. The wood shavings are then ground to the desired degree of fineness in a defibrinating device which is known per se. The process makes it possible to achieve up to 50 % reduction in grinding energy in comparison with known chemo-thermo-mechanical processes.

    Abstract: Method for selectively defiberizing and delignifying lignocellulose employing a novel alkaline pulping system. The subject pulping system includes a pulping liquor comprising water, a water-miscible organic reagent, and a sulfide or bisulfide compound selected from the group consisting of alkali metal sulfides and bisulfides, ammonium sulfide and ammonium bisulfide. Extremely high pulp yields as compared to kraft pulping are provided by employing the method and system of this invention.

    Abstract: Separation of a product of digestion of cellulosic biomass solids may be challenging due to the various components contained therein. Methods and systems for processing cellulosic biomass, particularly a reaction product of a hydrothermal reaction containing lignin-derived products, such as phenolics, comprise providing the reaction product to a separation zone comprising a liquid-liquid extraction unit. The liquid-liquid extraction unit can provide an aqueous portion and a non-aqueous portion, where these portions can be separated into various fractions individually. For example, desirable compounds in the aqueous portion and non-aqueous portion can be recovered from the portions individually and optionally combined to be further processed into a fuels product. Heavier components in the aqueous portion and non-aqueous portion can be recovered from the portions individually and used in the process, such as phenolics that can be used as a digestion solvent.

    Abstract: In some variations, a process is provided for producing a pulp product at a biorefinery site, comprising: converting a woody cellulosic material to a first pulp stream; converting a non-woody cellulosic material to a second pulp stream; blending the second pulp stream into the first pulp stream; and recovering or further processing the blended pulp stream as a pulp product. Biorefinery site infrastructure may be shared between the woody and non-woody lines. Also, the process may include process integration of mass and/or energy between the woody and non-woody lines. The process may be a retrofit addition to a pulp plant, or a greenfield biorefinery site. The non-woody line also can generate fermentable sugars, for fermentation to ethanol (or other products). Through allocation of carbon credits from the ethanol to the pulp, the final pulp product life-cycle profile can be improved.
