Abstrakt
The thermal decomposition of woody biomass was studied using pellets made from
residual processing spruce wood (Picea abies). The samples were studied using
thermogravimetric analysis in the isothermal regime at the temperatures 275 °C, 300 °C, 325 °C,
and 350 °C, which corresponds to the main decomposition region. The results show that the main
decomposition region can be described as a volatilisation of the main constituents at a temperature
higher than 300 °C. Otherwise, the results indicate, that the lignin does not decompose at lower
temperatures. Therefore, it can be concluded that the heating rate is one of the most important
parameters that affect the thermal decomposition of lignin and could lead to different
interpretations if non-isothermal measurements are used.
