Аннотация
The paper concerns the environmentally benign method of catalytic cellulose production by wood delignification over various catalysts using sulfur-free reagents – acetic acid and hydrogen peroxide. The optimum operation conditions (temperature and time of the process, H2O2/CH3COOH and liquor/wood ratios) of abies wood delignification using sulphuric acid as reagent and TiO2 as catalyst which allow reaching the acceptable yields of cellulosic product with high content of cellulose were selected.
