Abstract
Thailand relies heavily on crude oil imports, emphasizing the need for alternative, locally sourced energy solutions. This study highlights pyrolysis as a cost-effective method for converting biomass into energy and producing three primary outputs: pyrolysis oil, pyrolysis gas, and biochar. Fresh palm fruit bunches (FFB) from the Tenera strain were investigated as a feedstock for pyrolysis using a modified downdraft biomass gasifier and burner as heat sources. The FFB underwent size reduction to ensure a diameter of no more than 20 mm before pyrolysis. A 120-liter batch pyrolyzer was designed to maximize thermal efficiency and product yield. Key parameters, including pyrolysis temperatures of 400, 500, and 600 °C, were systematically analyzed. The highest yield of pyrolysis oil (24.66 %) was obtained at 400 °C, with chemical analysis identifying compounds such as naphthalene, heptadecanol, phenol, and methyl palmitate. Environmental evaluations showed significant reductions in greenhouse gas emissions, with 5.37 kg-CO2/kg-PPO less than LPG and 8.44 kg-CO2/kg-PPO less than electricity. This study demonstrates the feasibility of utilizing FFB for biofuel production and presents a sustainable framework for addressing energy demands in Thailand.
