摘要： Process for the production of an organic acid from a lignocellulosic feedstock. The process is integrated with a pulp mill and comprises: a) pre-treating a lignocellulosic feedstock with an alkaline liquor from the pulp, thereby obtaining a pretreated cellulosic feed and a black liquor; b) subjecting the pretreated cellulosic feed from step a) to enzymatic hydrolysis, thereby obtaining a saccharide feed; c) subjecting the saccharide feed from step b) to microbial fermentation using calcium oxide from the pulp mill as a neutralising agent, thereby obtaining an organic acid calcium salt; d) treating the organic acid calcium salt with sulfuric acid, thereby obtaining the organic acid; e) optionally isolating lignin from the black liquor obtained in step a), thereby obtaining lignin and weak black liquor; and f) returning the black liquor from step a) and/or the weak black liquor from step e) to the pulp mill chemical recovery process.

摘要： The invention relates to a continuous, scalable and parallelizable method for preparing strong and stiff fibers (filaments) or films. The fiber or film is prepared by utilizing hydrodynamically induced alignment of the constituents of a dispersion in combination with surface-charge controlled gel transition to produce fibers with a high degree of alignment of the constituents (polymer(s), fibrils etc). The invention also relates to the fibers or films so formed.

摘要： The present invention relates to a method of producing holocellulose fibres by treating a wood-based raw material with an organic peroxide, wherein the method comprises charging the organic peroxide continuously to the wood-based raw material during the treatment and/or charging the organic peroxide to the wood-based raw material in at least two separate steps with an intermediate alkaline treatment step. Additionally, a process for the production of paper comprising the steps of preparing a papermaking stock comprising an aqueous pulp slurry comprising cellulosic fibres and having a fibre consistency of from 0.1 to 40% by weight, wherein the cellulosic fibres comprise or consist of holocellulose fibres, and wherein the amount of the wood-based holocellulose fibres is from 0.5 to 100% by weight, based on the total weight of the stock; providing the stock to a wire and form a web; dewatering the web; and drying the web is claimed. By the method affordable way to produce holocellulose fibres usable in the process to provide paper with high strength is provided, while effective dewatering can be obtained during the manufacturing process.

摘要： Process for the production of a cured pulp product suitable for use in the production of paper, paperboard, tissue paper, filter paper or fluff pulp, comprising the steps of attaching an anionic or amphoteric carboxymethyl cellulose (CMC) to cellulosic fibres in acidic conditions or in the presence of divalent metal ions. Aluminium ions or divalent ions are then added to the slurry to a total molar concentration of from 0.0001 M to 0.5 M in the first pulp slurry. The first pulp slurry is then dewatered and cured in acidic conditions and a cured pulp product is provided. The cured pulp product is subsequently used in a paper making process to provide a paper-based product, whereby higher bulk is provided for the final paper-based product. Alternatively, the curing step is omitted and instead aluminium ions are added to the first pulp slurry and the pulp is directly used in a paper making process.
