This project describes the process to obtain biocarbon pellets from the lignocellulosic residual biomass (African palm rachis). The process began with a physicochemical characterization of biomass for the analysis of the properties that benefit the coal formation, a proximal analysis, cellulose, lignin and hemicellulose content were determined and the TGA of the sample was analyzed. Subsequently, biochar was obtained through two thermochemical processes (Torrefaction and HTC) in a batch reactor of 1 L capacity. Temperatures of 210, 230 and 250 �?°C, times of 15.0, 22.5 and 30.0 min and with two types of atmosphere (inert and oxidative) were applied, the caloric power was determined and a proximal analysis was performed. The optimum value was obtained at a temperature of 250 �?°C, a time of 30 min, an oxidative atmosphere by the torrefaction method. It was determined that the calorific value increased as the temperature applied in the biomass transformation process increased while the content of volatiles and ash decreased with optimal values of 27.28 MJ/kg, 50.16% and 1.00%, respectively. Finally, the biochar obtained was used to determine the effect of the binder (corn starch) on pelleting, where the concentrations used were 0, 5 and 10%. The properties analyzed were durability, water resistance, impact resistance, proximal analysis and calorific power. It was evidenced that higher concentration of binder agent increases the caloric power, durability and impact resistance but the water resistance was lower. crissa21292@gmail.com
