Purpose is to develop environmentally friendly processes to obtain from the stalks and fibers NW cellulose products (packaging types of paper and cardboard, microcrystalline cellulose, cellulose for chemical processing, carboxymethyl cellulose, nitrocellulose). The fractional and chemical composition, microscopic and electron structure of stalks and fibers of various members of NW (kenaf, hemp, flax, miscanthus, rape, sverbihy, wheat, sunflower). The influence of the main process parameters to obtain cellulose in various ways delihnifikatsiyi plant material on indicators of quality. A diagram and built out depending on the content of pulp residual lignin in it to assess the effectiveness of processes delihnifikation plant material. Indexes selectivity (degree delihnifikatsiyi, selectivity, the degree of removal of hydrocarbons) removal of lignin from plant material in different ways delihnifikatsiyi. It was established that the best selectivity among the studied methods delignification sunflower stalks characterized alkali sulfite-alcohol pulping method. Calculated analytical and graphical methods of kinetic parameters (rate constants and activation energy) processes of non-wood cellulose from plant material. The optimum composition for fiber for packaging types of pulp and paper products using a composition of cellulose with NW. The influence of acid stage peredhidrolizu fibers of flax, hemp and kenaf and stage of chelating treatment on quality parameters of microcrystalline cellulose. Established that delihnifikatsiya fiber crops (flax, hemp and kenaf) combined alkaline orhanosolventnym method followed by bleaching lets cellulose, which is suitable for chemical processing. An dynitrocellulose with a nitrogen content 12.88% to 12.97% hemp and kenaf for. The possibility of using soda and sulphite pulp neutral bast of flax and hemp for Na-carboxymethylcellulose. Developed and approved by the regulatory and technical documentation for the production of cellulose for chemical processing and microcrystalline cellulose. Non-woody plant material, pulp, paper, paperboard, microcrystalline cellulose, nitrocellulose Product Description popup.authors Алушкін С.В. Каракуца М.Г. Лисоконь Л.Г. Лобова С.В. Микитюк Т.М.
