The samples were fed to a devolatilization process at 900 °C in a tubular drop reactor (-0.25 mm) and a batch-type fixed bed reactor (-20 mm). The morphology of the char was determined through image analysis. The surface area was evaluated by BET analysis for particle size -0.25 mm. The results showed that for particle sizes -20 mm synergistic effects were obtained towards the generation of reactive morphologies (thin walls + thick walls) with the increase in bagasse concentration. It was found that coal generated a higher concentration of thick and solid wall morphologies.</p&gt;}, number={40}, journal={Revista Ingenierías Universidad de Medellín}, author={García-Saavedra, Edward Andrés and Torres-Velasco, Alejandra and Medina-Ramírez, Cristian Dubiany and Barraza-Burgos, Juan Manuel and Guerrero-Pérez, Juan Sebastián}, year={2021}, month={Dec.}, pages={44-66} }
