New methods have been developed for obtaining powder lignocelluloses substances from vegetable raw materials, including wastes of wood-working industry and agriculture. The products are fine powders obtained by the acid catalytic methods of plant material destruction in aqueous and anhydrous environments; they possess a set of useful properties of cellulose and lignin and are enriched with functional groups.

Originality of the approach: the use of catalytic thermal processes to obtain the desired products; the application of anhydrous easy-regenerating media free from harmful emissions into the environment.

Major advantages: renewable vegetable raw materials; environmentally friendly material; availability of raw material supply; ease of chemical processing of raw materials; and a wide range of applications.

Fields of Application: stabilizing and binding agents, carriers and sorbents in chemical industry.
