摘要： This invention provides for the recovery of lignin and other by-products from the pulping of fibrous plant material. In accordance with this invention, solvents and filtrates are recovered and recycled for reuse. This results in significant solvent and energy savings. Filtrates from the bleaching and delignification of the pulp are recycled for reuse in pulping, separation, and recovery of lignin and other by-products which results in significant energy savings and mitigation if not the elimination of pollution typically associated with bleaching. This invention also relates to products derived from the process and apparatus for carrying out the process. Lignins of various molecular weights and by-products of the pulping process are also recovered. The lignins are precipitated in high yields and at a high rate from a black liquor produced by pulping wood at high temperature and pressures. As a by-product of this process a purified furfural product is recovered. This furfural may be recycled for use in the recovery of the low molecular weight lignin of this process.
摘要翻译：本发明提供从纤维植物材料的制浆中回收木质素和其它副产物。根据本发明，回收溶剂和滤液并循环再利用。这导致显着的溶剂和能量节省。来自纸浆漂白和脱木质素的滤液被再循环用于制浆，分离和回收木质素和其它副产物，如果不消除通常与漂白相关的污染，则可以显着节能和减轻。本发明还涉及从用于实施该方法的方法和装置得到的产物。各种分子量的木质素和制浆过程的副产物也被回收。木质素以高产率和高速率从由高温和高压制浆木浆产生的黑液中沉淀出来。作为该方法的副产物，回收了纯化的糠醛产物。该糠醛可以再循环用于回收该方法的低分子量木质素。

摘要： A process of treating a lignocellulosic material includes a pre-extraction step in which hemicellulose is extracted from the lignocellulosic material. In one embodiment, the pre-extraction step involves contacting the lignocellulosic material with an aqueous solution under conditions that release acidic material from the lignocellulosic material into the aqueous solution, and the aqueous solution includes a basic material that at least partly neutralizes the acidic material so that the aqueous solution at the end of the pre-extraction step has a pH within a range of from 4.5 to 11. The process also includes a pulping step, after the pre-extraction step, in which the lignocellulosic material is separated into pulp. The process further includes an adsorption step, after the pulping step, in which hemicellulose is adsorbed on the pulp.

摘要： A method of producing a soft paper product incudes, a) providing a pulp sheet at a moisture content of no greater than about 10%, the pulp of said sheet not having been previously subjected to dry milling and not being predominately anfractuous; b) treating the pulp sheet at moisture content of no greater than about 10% with liquid ammonia of a concentration of at least 90% for a period of time less than or equal to about 60 seconds effective to increase degree of softness in the sheet of pulp from that existing prior to the treating, the pulp in the treated sheet remaining not predominately anfractuous after said treating; c) forming the treated pulp sheet into a papermaking slurry; and d) feeding the papermaking slurry into the headbox of a paper machine and producing a tissue paper product therefrom which has greater softness than a tissue paper product made from the same pulp which has not been so treated with said ammonia.
