PRODUCTION AND CHARACTERIZATION OF BIO-OIL FROM PYROLYSIS OF BIOMASS WASTE: A COMPARATIVE STUDY

Abstract

Faced with resource scarcity and the increasing demand for sustainable solutions, the recovery of agricultural waste presents a promising alternative. This study investigated the pyrolysis of sugarcane straw (PC), brewer waste (BW), and banana tree straw (PB) for the production of bio-oil. The samples were analyzed using thermogravimetric analysis (TG/DTG), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR) to determine their chemical composition and evaluate how the main constituents (cellulose, hemicellulose, and lignin) influenced the properties of the bio-oil. Analytical pyrolysis allowed for the identification of compounds present in the bio-oil. Banana tree straw, which is rich in hemicellulose, produced higher levels of carbon dioxide. In constrast, brewer waste and sugarcane straw, which are rich in lignin, generated greater amounts of phenols and anhydrous sugars. The results demonstrated the potential of pyrolysis for converting agricultural waste into bio-oil, highlighting that the chemical composition of biomass significantly affects the quality and quantity of the products obtained.
