摘要

Open-field burning of agri cultural residues significantly contributes to regional air pollution and environmental degradation. This study investigates the potential of four commonly available crop residues like rice straw, wheat straw, maize straw, and barley straw, for charcoal production through pyrolysis. The experimental investigations were carried out to calculate the influence of the pyrolysis parameters on the charcoal production yield and emission factor. Thermodynamic and exergy analyses were employed to assess the quality and efficiency of the process. Results indicated that increasing pyrolysis temperature led to a reduction in charcoal yield by 15.2%, 12.5%, 17.7%, and 16.7% for rice straw, wheat straw, maize straw, and barley straw, respectively, while significantly lowering emissions compared to raw straw combustion. Among the tested residues, wheat straw exhibited the highest energy and exergy performance. This study presents a comprehensive comparative assessment of crop residue pyrolysis, offering practical insights for clean energy production and pollution mitigation, especially in developing countries.
