Abstract
ABSTRACTThis research investigates the conversion of Hydrilla verticillata into bio-oil and charcoal through a continuous pyrolysis process. The pyrolysis was carried out at a controlled temperature in the range of 300–700°C. The bio-oil and charcoal were analyzed using elemental analysis, chemical composition, and Scanning Electron Microscope-Energy Dispersive X-ray (SEM-EDS). At the highest temperature of 700°C the maximum product yield of bio-oil (41.25%) was found, while the maximum product yield of charcoal was 44.98% at 300°C. These results indicate the influence of temperature variation. The analysis of the Hydrilla verticillata mixture found a great portion of large molecules, including phenols (-OH), esters (-C=O), aldehydes (-CHO), and ketones (-C=O). The SEM analysis of the charcoal determined the enhancement of specific surface areas and microporosity, indicating an active diffusion rate, which may make the product suitable for fuel applications.
