Exploring the Critical Factors of Biomass Pyrolysis for Sustainable Fuel Production by Machine Learning

Sustainability, Journal Year: 2023, Volume and Issue: 15(20), P. 14884 - 14884

Published: Oct. 15, 2023

The goal of this study is to use machine learning methodologies identify the most influential variables and optimum conditions that maximize biochar, bio-oil, biogas yields for slow pyrolysis. First, experimental results reported in 37 articles were compiled into a database. Then, an explainable approach, Shapley Additive exPlanations (SHAP), was employed find effects descriptors on targets, it found higher biochar can be obtained at lower temperatures using biomass with low volatile matter high ash content. Following that, decision tree classification used discover leading levels generalizable path yield where maximum particle diameter less than or equal 6.5 mm temperature greater 912 K. Finally, association rule mining models created associations very yields, among many findings, discovered larger particles cannot converted bio-oil efficiently. It then concluded methods help determine best pyrolysis production renewable sustainable biofuels.

Process optimization of rice straw-derived activated biochar and biosorption of heavy metals from drinking water in rural areas

Applied Surface Science Advances, Journal Year: 2023, Volume and Issue: 18, P. 100481 - 100481

Published: Oct. 27, 2023

The Indo-Gangetic plain of northern India is known for prevalent rice farming. Due to the lack a straw waste management system, large volume burned in field. Therefore, we add value by converting it into activated biochar and utilizing remove toxic metals from natural water. In this work, single-step physical activation (CO2 H2O) was planned optimized process parameters get better yield surface area. were using central composite design method. CO2 has an optimum area product 399.99 m2/g 26.79 %, whereas H2O 31.53 % 300 m2/g. SEM analysis shows that more uniform porous structure than biochar. Cost revealed had lower manufacturing cost 1.287 1.672 U.S. $/kg, respectively compared other adsorbents. Arsenic manganese removal efficiency water found be greater 95 both
