Harbin Institute of Technology Develops Microwave Method for High-Performance Biochar from Sugarcane Waste
Researchers at the Harbin Institute of Technology have developed an optimized microwave-assisted pyrolysis method to convert sugarcane bagasse into high-quality biochar. The study employed response surface methodology to fine-tune pyrolysis temperature, potassium hydroxide (KOH) activation, and CO₂ flow rate.
The optimal conditions were identified as approximately 803 °C, 64.5 grams of KOH, and 68 cm³/min CO₂ flow, resulting in a specific surface area exceeding 1,156.37 m²/g. The findings highlight the balance between maximizing surface area and maintaining structural integrity, crucial for applications in pollutant adsorption and energy storage. This innovative approach integrates experimental precision with statistical modeling, contributing to sustainable biomass valorization.
