This work presents a comprehensive study on the modeling of drying, pyrolysis, and combustion of biomass for biochar, heat, and electricity production. Utilizing an ideal stirred reactor model, the study simulates the thermochemical processes involved in biomass conversion, focusing on a waste wood as primary feedstock. It examines the impacts of temperature, moisture content, and oxygen concentration on biochar yield and the production rates of key gases such as carbon monoxide, hydrogen, and methane. The study highlights the optimal temperature ranges for drying, pyrolysis, and combustion to maximize biochar yield and minimize undesirable byproducts like ash and PAHs. Chemical kinetics are based on the works of Ranzi et al. 19-21. Results underscore the critical role of process parameters in optimizing biochar production, offering insights into the challenges and solutions associated with biomass conversion technologies. arrowdownwardDownload PDF
