Abstract:
The resourceful utilization of agricultural wastes represents a crucial approach to achieving sustainable agricultural development. This study proposes a coupled carbonization-gasification system and conducts a thermodynamic analysis of its behavior. Initially, agricultural wastes are converted into biochar through carbonization technology, while combustible gases are simultaneously released. Subsequently, gasification technology is employed to further transform the biochar into high-calorific-value gases, thereby enhancing energy utilization efficiency. A thermodynamic model is utilized to calculate and optimize key parameters of the coupled system, and the influences of factors such as temperature, raw material composition, and reaction heat on system performance are analyzed. The results indicate that this coupled system can significantly improve energy conversion efficiency, reduce carbon emissions, and simultaneously realize high-value resourceful utilization of wastes. The research demonstrates that this technology holds broad application prospects in the treatment of agricultural wastes and energy recovery, providing theoretical support and technical references for green agriculture and sustainable energy development.
