| Summary: | The search for alternatives to energy derived from fossil sources to decarbonize the environment has been growing in recent years. Therefore, the use of waste to generate energy has been a viable alternative. Among the different types of processes used to transform biomass into energy, pyrolysis, a thermochemical process, stands out for its process versatility and diversity of products for energy applications. This process consists of the thermal decomposition of the organic matrix of the biomass in the absence of oxygen or with a substoichiometric amount of air to avoid combustion, which can produce bio-oil, biochar, and gaseous products. In this context, kinetic parameters obtained from the literature on thermal degradation of biomass were used to evaluate the behaviour of the operating conditions of the process, aiming to obtain optimal product distributions. For this purpose, the COCO (Cape-Open to Cape-Open) simulator with CSTR (Continuous Stirred-Tank Reactor) reactor was used. For these evaluations, parametric studies were performed regarding temperature. The characterization of sugarcane bagasse was crucial for data entry into the simulator, providing real data on the raw material. Thus, proximate, ultimate, and biochemical analyses were performed. The simulation of this process covers the main stages: biomass drying, pyrolysis process, and products separation – biochar, bio-oil, and combustible gases. With fast pyrolysis operating conditions (500 °C), it was possible to obtain the expected yield of liquid products (more than 58 %) in the process. |
