Resumen:
Physicochemical properties of the charcoal arising from pyrolysis of sugarcane
bagasse at 600 °C and 800 °C were determined to evaluate potentialities for
specific end uses. The charcoals were found fairly adequate as solid bio-fuels. Their
quality was comparable to charcoals obtained from some other agro-industrial byproducts, reportedly proposed as substitutes of wood-based ones. Surface properties of the charcoal generated at the higher temperature indicated that it is reasonably
suited for potential use as low-cost rough adsorbent, soil amender, and/or for further
upgrading to activated carbon. Moreover, kinetic measurements for pyrolysis of
the sugarcane bagasse individually and mixed with an Argentinean subbituminous
coal in equal proportions were conducted by thermogravimetry for the range 25 °C ?
900 °C. Data modeling accounting for variations in the activation energy with process
evolution provided a proper description of pyrolysis and co-pyrolysis over the entire temperature range
