Abstract

The increasing need for sustainable energy sources and effective waste management solutions has driven significant interest in the production of biochar through biomass pyrolysis. This research proposal focuses on the characterization of biochar produced from the co-pyrolysis of Gmelina arborea and Parkia biglobosa using a fixed bed reactor. The primary objective is to investigate the synergistic effects of these two biomass feedstocks to optimize the yield and enhance the fuel properties of the resulting biochar. By conducting systematic experiments, the study aims to provide valuable insights into the potential of mixed biomass co-pyrolysis for biochar production. The experimental procedure involves meticulous preparation of the feedstocks, followed by their co-pyrolysis in a fixed bed reactor under controlled conditions. Post- pyrolysis, the resulting biochar will undergo comprehensive characterization using various standard techniques. Parameters such as moisture content, volatile matter, fixed carbon, ash content, elemental composition, higher heating value (HHV), thermal stability, and chemical functional groups will be analyzed. Techniques like proximate and ultimate analysis will be employed to evaluate these properties, ensuring a thorough understanding of the biochar’s characteristics. The findings from this research are expected to elucidate the optimal conditions for maximizing biochar quality and yield from th
