The influence of treatment conditions on wood structure and on activated wood acidic hydrolysis was studied. It was found that the preliminary mechanical activation on aspen wood increases the yield of easy – hydrolyzed polysaccharides and the rate of their hydrolysis to sugars with 2 % HCl. The higher influence on the reaction ability in hydrolysis process was observed after aspen wood treatment in a planetary activator mill AGO – 2. Keywords: aspen wood, mechanical treatment, structure, acidic hydrolysis, intensification. Mechanical and mechanochemical processing is widely used in technologies of lignocellulosic raw materials conversion to target materials and chemical products. A variety of equipments like machine of knife grinding, jet grinding, vibrating mills, mechanochemical activators of centrifugal and planetary types, cavitational devices and etc. which differ in nature of action on crushed materials was applied with this purpose. Theoretical basis of grinding process of fibrous materials are considered in monograps [1–4]. Milling of wood biomass in aqueous medium is a complicated mechanical process which resulted in * Corresponding author E-mail address: inm@icct.ru 1 © Siberian Federal University.

Treatment in disk knife mills can be considered as a set of mechanical and hydrodynamic action on wood biomass which lead to the changes in dispersion of water suspensions and to the disintegration of wood fibers [2]. It is been shown [8], that the destruction and compression of external Р and S1 layers of a wood cell, which prevent swelling and fibrillation of fibers take place in the process of knife grinding [5]. Destruction of these layers uncovers bulk structure of a secondary wall of a cell – layer S2, and facilitate the consumption of water. The processes of fibrillation swelling and
