Numerical Modeling of a High-Efficiency Pyrolysis System for High-Quality Biochar Production from Various Biomass
Short Introductive summary
In this study, the pyrolysis characteristics of various biomass feedstocks were analyzed to optimize biochar production with respect to quality, energy efficiency, and byproduct utilization. Furthermore, in this study, an analytical model was developed to design an efficient pyrolysis process capable of producing biochar and bio-oil at 500°C while minimizing external heat supply. The model was implemented using Microsoft Excel VBA and validated against pilot-scale pyrolysis experiments. The modeling was conducted under steady-state and one-dimensional assumptions, considering constant particle size before and after devolatilization and equal temperatures for volatiles and biochar. Simplified assumptions were applied to the radiation model and volatile composition for computational efficiency. The results demonstrated that pyrolysis gas possessed sufficient energy to sustain the process heat demand; however, efficient flue gas recirculation was essential to enhance flow and heat transfer rates. The developed numerical model provides a practical tool for predicting temperature profiles and heat transfer behavior in commercial-scale pyrolysis systems based on biomass analytical data.
