Abstract

This scientific investigation explores the conversion of olive pomace waste from Moroccan oil mills into valuable biomass energy via pyrolysis. The study involves three pivotal parts: Our research encompasses a multifaceted approach, beginning with a comprehensive review of olive pomace, pyrolysis, gasification, and biomass combustion to establish a robust foundational knowledge base. Following this, we embark on developing a physical and mathematical model for pyrolysis alongside determining crucial thermo-physical properties, thus setting the stage for subsequent simulations. In the final phase, our study conducts intricate simulations of the pyrolysis process, precisely calculating gas and solid temperatures at multiple pivotal points while accounting for fluctuations in solid temperature due to gas interactions. Employing a TDMA (Thomas Algorithm) approach to iteratively solve the system's equations, we simultaneously derive temperature values for both gas and solid phases. Notably, our research integrates critical thermal data, including the initial assumption of a uniform solid temperature at 293 K, an incoming gas temperature of 600 K, and an existing gas temperature post-pyrolysis of 514.52 K, while considering non-uniform solid temperatures. This comprehensive research underscores the potential of pyrolysis as a sustainable biomass energy source, addressing waste management concerns and championing environmental sustainability.
