Tsyganova, Nikolai V. Chesnokov and Boris N. Kuznetsov* Institute of Chemistry and Chemical Technology SB RAS 50/24 Akademgorodok, Krasnoyarsk, 660049, Rossia Received 19.01.2015, received in revised form 12.02.2015, accepted 01.03.2015 The infl uence of birch and aspen wood modifi cation by explosive autohydrolysis and ZnCl2 additive on the yield, composition and porous structure of carbon products obtained for carbonization of modifi ed wood has been studied. <...> It was shown that the aspen wood is subjected to a more profound transformation in the processes of explosive autohydrolysis and carbonation than the birch wood. <...> The yield of the carbon product increases up to 40 %, and the specifi c surface area rises by two orders for carbonation of autohydrolyzed wood modifi ed by ZnCl2 regardless on the nature of wood. <...> It was shown that the processes of intensive thermal decomposition of the modifi ed wood are carried out at lower temperatures, as compared to the initial wood. <...> Keywords: birch and aspen wood, modifi cation, explosive autohydrolysis, ZnCl2 chloride, carbon product © Siberian Federal University. <...> All rights reserved * Corresponding author E-mail address: bnk@icct.ru , carbonization, zinc # 92 # Svetlana I. <...> Study of the Carbonization of Birch and Aspen Wood Modifi ed… <...> Изучение карбонизации древесины березы и осины модифицированной взрывным автогидролизом и добавками ZnCl2 С.И.
