摘要： A method of wood pulping having a significantly increased yield is disclosed. Wood chips are chemically pulped to a high kappa number, providing a first accepts component and a first rejects component. The first rejects component is subjected to a high consistency pulping process such as a substantially mechanical pulping process to generate a second accepts component and a second rejects component. The first accepts component may be used in the production of saturating kraft paper with excellent saturability and resin pick up. The second accepts may be used as a second fiber source in the production of multiply linerboard and unbleached paperboard with enhanced stiffness, strength, and smoothness. Alternatively, the first accepts component may be blended with the second accepts component to produce fiber blends, which may be used in a production of paper-based products having enhanced strength and stiffness at low basis weight.

摘要： The present invention relates to regulation of the p H of a liquefaction process. Presented is a method for treatment of a biomass feedstock wherein the biomass feedstock is subjected to liquefaction, at a p H of at most 4, by treatment with hot compressed liquid water (HCW) at subcritical and/or supercritical conditions to improve the conversion efficiency. The present invention is also directed to quenching of a liquefaction process according to above, preventing, minimizing or eliminating clogging and/or fouling of sticky biomass components in process equipment during processing as according to above, and to the use of additives in a biomass liquefaction process.

摘要： The present invention is directed to a process for producing spinnable cellulose at least in part from citrus fruits, such as oranges and lemons. In a preferred embodiment, cellulose is extracted from citrus fruits, discarded by the citrus fruits plantations and/or from parts of citrus fruits, waste of the industrial processing of citrus fruits derivatives. Cellulose is extracted from the entire peel of citrus fruits, which includes both albedo and flavedo, or only from albedo. Preferably, cellulose is obtained by chemical extraction, preferably in the absence of chlorine, comprising the treatment of raw materials derived from citrus fruits with hydrogen peroxide under basic conditions. Cellulose obtained by the process of the present invention is optionally mixed with cellulose obtained by different processes, for example with cellulose extracted from wood.

摘要： Alkali surfactant compositions and treatment processes. The alkali surfactant composition has a surface tension (at 100 ms) of from [0.8 asymptote] to [1.2 * asymptote]. The composition can be used in treatment processes, such as cleaning, chemical pulping, mercerization, metal processing, leather processing, food processing, and personal beauty care. The process comprises the step of contacting a substrate with an effective amount of an aqueous alkali surfactant composition having a hydroxide Molarity of from 2 to 9. The composition comprises (a) alkali; and (b) a surfactant having a Lewis acid head group positioned terminally in a linear or branched aliphatic hydrocarbon chain comprising from 4 to 10 aliphatic carbon atoms.
