Abstract:
The purpose of this work is to make a comparative study of the thermal degradation of herbaceous and woody biomasses, in order to forecast possible differences that could be useful to differentiate their combustion conditions. Thermal techniques used were TG and DTA. Derivative of TG (mass loss per unit of time at a determinate temperature- DTG) gave information about the reactivity of the studied biomasses Results obtained showed a lower starting degradation temperatures and higher reactivity for herbaceous biomasses (1.16 and 1.22 mg min-1 C-1) compared to woody materials (1.69 and 1.34 mg min-1 C-1). Both groups of biomasses showed typical DTA and DTG patterns for each of the groups that were related to the different composition of the materials. As a conclusion, it can be said that thermal analysis is a useful tool to establish differences in the degradation behavior of herbaceous and woody biomasses that can be useful to establish differential combustion strategies for these two types of biomasses.
