EFFECT OF WATER TREATMENT PROVISIONAL PINE SAWDUST WOOD FOR STRUCTURAL CHANGES AND PROPERTIES CARBON PRODUCTS BASED ON IT
Abstract
The effect of long-term water extract of pine sawdust on the structure of wood and its carbon product. It is found that such a timber processing increases the fraction of the amorphous phase and the content of hydrogen in its composition. Using X-ray diffraction is determined that the processing of wood after water decreases the crystallinity of cellulose and increases the width of the crystallite size. It is revealed that an increased content of amorphous component in the timber after the water processing is stored in the structure of the carbon product based on it, compared with an untreated timber and its product.
The possibility of producing porous carbon materials from sawdust pine subjected to long exposure to water. Carbonation of these chips, up to 800 °C leads to the formation of a porous carbon product, specific surface of which is 400 times higher than the specific surface area of product obtained from conventional chips in the same conditions. It is assumed that the disclosure of the porous structure of the carbon product from the timber after the water treatment due to the change of its structure, including the expansion of the crystal lattice of cellulose, and removing formed during carbonization of low molecular weight fragments.
