This paper presents a study about the effect of excess air and the inert fixed bed height upon the characteristics of fine charcoal particles and the main reactor parameters. The pyrolysis process is considered as a method to concentrate carbon in fine charcoal particles and a method to reduce oxygen content in the biomass.The study concludes that the operation point which gives the highest percentage if carbon fine charcoal particles and reduces the most the oxygen in biomass corresponds to a fixed bed height of 207 mm and excess air of 8%.
