Abstract

<p>Overgrowth of water hyacinth (WH) poses environmental and economic challenges. This study explores the potential of utilizing WH biomass as solid fuel through hydrothermal carbonization (HTC). HTC converts high-moisture organic waste into biochar and bio-oil. While increasing the temperature during HTC improves bio-oil yield, it reduces energy recovery. Mixing WH with other biomass and adding citric acid enhances the process, particularly in bio-oil yield and energy recovery. The research revealed that citric acid enhanced bio-oil yield and energy recovery, indicating its role in promoting synergistic reactions in co-biomass hydrothermal carbonization.</p>
