摘要： Objective of the method is a procedure for production of nanocellulose, where energy consumption and other costs of production are lower than in methods presented previously. It is based on separation of minute particles from cellulose or plant based ingredients by effects of light, thermal energy or water-soluble organic solvents. These particles act as precursors of nanocellulose. After separation they form in dry state aerosol, in liquid media a suspension, and combine to chains, microfibrils and secondarily formed fibrils, which form further networks with each other or with other fibres and fibrils. Applications are based on their action as reinforcing structure in composites, paper, cardboard, paints and other materials, on forming thin-layer films for electrical, electronic and medical applications, or on viscosity, surface and permeability properties.

摘要： Technology for separating lignin from alkaline solutions which arise in production of cellulose is presented. Isolated lignin can be applied, for instance, for production of carbon fibre, adhesives and binding materials, antioxidants and organic chemicals. Starting materials are non-woody plant materials, from which lignin is dissolved by sulphur free alkaline solutions at temperatures below 130°C. Lignin is precipitated by acid, and purified by hydrolyzing hemicellulose by acid or by enzymatic reactions or a combination of these. Lignin separated has a closely similar structure as lignin in plant material, and its content of functional atom groups can be controlled by changes in processing conditions.
摘要翻译：介绍了从纤维素生产中出现的碱性溶液中分离木质素的技术。例如，分离的木质素可用于生产碳纤维，粘合剂和粘合材料，抗氧化剂和有机化学品。起始材料是非木质植物材料，在低于130℃的温度下，木质素通过无硫碱性溶液从中溶解。木质素通过酸沉淀，并通过酸或通过酶促反应或这些的组合来水解半纤维素来纯化木质素。木质素分离的结构与植物材料中的木质素结构非常相似，其功能原子基团的含量可以通过改变加工条件来控制。
