摘要： A multi-function process for hydrolysis and fractionation of lignocellulosic biomass to separate hemicellulosic sugars from other biomass components comprising extractives and proteins; a portion of a solubilized lignin; cellulose, glucose derived from cellulose; and insoluble lignin from said biomass comprising: a) introducing either solid fresh biomass or partially fractioned lignocellulosic biomass material with entrained acid or water into a reactor and heating to a temperature of up to about 185°C-205°C; b) allowing the reaction to proceed to a point where about 60 % of the hemicellulose has been hydrolyzed in the case of water or complete dissolution in case of; c) adding a dilute acid liquid at a pH below about 5 at a temperature of up to about 205 °C for a period ranging from about 5 to about 10 minutes; to hydrolyze the remainging 40 % of hemicellulose if water is used; d) quenching the reaction at a temperature of up about 140 °C to quench all degradation and hydrolysis reactions; and e) introducing into said reaction chamber and simultaneously removing from said reaction chamber, a volumetric flow rate of dilute acid at a temperature of up to about 140 °C to wash out the majority of the solubilized biomass components, to obtain improved hemicellulosic sugar yields.

摘要： The invention relates to a method for removing chemically bound formic acid from a material containing the same, in the presence of free formic acid. The method is characterized in that chemically bound formic acid is allowed to react to free formic acid at a normal pressure, at a temperature of less than 100 °C, the initial content of free formic acid being about 3 to 20 %. The reaction time is typically 0.5 to 4 hours. The material to be treated may be, for instance, material, obtained from a formic-acid-based pulp cooking process, containing cellulose and/or lignin.

摘要： A method for oxidative degradation of lignin and polysaccharide fragments dissolved during polyoxometalate delignification or bleaching of wood pulp, wood fiber or pulp or fiber obtained from a non-woody plant. The method comprises the steps of obtaining a spent polyoxometalate bleaching solution containing a polyoxometalate of the formula [V1MomWnNboTap(TM)qXrOs]x- where 1 is 0-18, m is 0-40, n is 0-40, o is 0-10, p is 0-10, q is 0-9, r is 0-6, TM is a d-electron-containing transition metal ion, and x is a heteroatom; which is p or d block element, provided that 1 + m + n + o + p » 4, 1 + m + q > 0 and s is sufficiently large that x > 0, and heating the solution in the presence of an oxidant under conditions wherein the dissolved organic compounds are oxidatively degraded to volatile organic compounds and water. The invention is further based upon the use of less caustic and less corrosive non-vanadium containing polyoxometalates for delignification or bleaching of wood pulp, wood fiber, or pulp or fiber obtained from a non-woody plant.
