Improving the prediction of biochar production from various biomass sources through the implementation of eXplainable machine learning approaches

International Journal of Green Energy, Journal Year: 2024, Volume and Issue: 21(12), P. 2771 - 2798

Published: March 14, 2024

Examining the game-changing possibilities of explainable machine learning techniques, this study explores fast-growing area biochar production prediction. The paper demonstrates how recent advances in sensitivity analysis methodology, optimization training hyperparameters, and state-of-the-art ensemble techniques have greatly simplified enhanced forecasting output composition from various biomass sources. argues that white-box models, which are more open comprehensible, crucial for prediction light increasing suspicion black-box models. Accurate forecasts guaranteed by these AI systems, also give detailed explanations mechanisms generating outcomes. For models to gain confidence processes enable informed decision-making, there must be an emphasis on interpretability openness. comprehensively synthesizes most critical features a rigorous assessment current literature relies authors' own experience. Explainable encourage ecologically responsible decision-making improving forecast accuracy transparency.

Nowadays, the scarcity of energy resources is promoting search for alternative sources, boosting interest in use forest lignocellulosic residue sector. In this study, focus on recovery from two residues originated during pruning ornamental trees (Horse Chestnut, CI, and False Acacia, FA). Both conventional flash pyrolysis techniques were applied. The experimental variables obtained study thermal behaviour thermogravimetric analysis. It was carried out under 5 heating rates kinetic parameters estimated using Flynn-Wall-Ozawa method. Results denoted higher maximum mass loss rate values same release temperature regions FA experiments. Also, samples had lower final processes. However, activation so close both species. also linked to faster reactions according frequency factor outcomes. Conventional a horizontal oven original design at 25 °C/min, 750 °C 60 min permanence that temperature; tested 850 °C. these processes, three fractions obtained: bio-char, bio-oil gas. physicochemical attributes bio-chars suggested their potential utility as biofuels (28.4–29.8 MJ/kg), adsorbent precursors or soil additives. bio-oils dominant monoaromatic hydrocarbons nature, with phenols being most abundant (≥60%), while contain mainly polycyclic aromatic hydrocarbons. gases contained up vol% CO2; high combustible gas content (CO, CH4, H2) low CO2 (<25 vol%).
