Abstract
A wood treated at temperature below 300 deg C and under inert atmosphere is chemically modified without reducing too much its mechanical properties. The topics of this work is to find the optimal conditions for the pyrolysis proceed. The conditions of the manipulation are very important to obtain the final product. Coniferous wood begins to damage about 188 deg C the one of broad-leaved about 195-205 deg C. The microscopic aspect of wood is preserved. In the opposite for a pyrolysis at 250 deg C the crystalline structure of the cellulose is modified especially in the longitudinal-tangential plan. The high carbonylations and condensations which exist at 240 deg C seem to be very interesting. The measure of the colour of the samples can be a fast means to control the treatment proceeding. The pyrolysis wood properties allow new applications for the wood.
