This experiment aims to improve the properties of used engine oil that has been in operation for 12,000 kilometers. The oil is subjected to a fast pyrolysis process in a drop tube furnace at temperatures of 400, 450, 500, 550, and 600 degrees Celsius, with oil feed rates of 50 and 100 milliliters per hour. The objective is to investigate the properties of the oil after undergoing rapid pyrolysis treatment, including heat value, density, viscosity, acidity, flash point, and ignition point, according to ASTM standards. The experimental results are compared with diesel and biodiesel fuels to provide guidance for decision-making in the production of biofuels for single-cylinder small engines used by farmers.
