Indonesia targets net zero emissions by 2060. Therefore, pyrolysis from biomass is a promising first step in the transportation fuels-making process. This study aims to investigate the pyrolysis oil and the charcoal produced from the pyrolysis process of oil palm fronds in a 40 L rotary drum reactor. These pyrolysis products can be used as raw materials for bio-fuel and bio-carbon black. The research methodology is to conduct experiments on the conversion of palm fronds into pyrolysis oil and charcoal with variations in heating rates and pyrolysis temperatures, and also with and without the use of heat carrier media (steel shots S330). Based on the experiment results, optimal heating is carried out at a temperature of 500˚C for 1 hour, where it produces the most pyrolysis oil at 37.0%, followed by 30.4% charcoal and 32.6% gas. This pyrolysis oil has a heating value of 16 MJ/kg, 38.3% water content and 38.2% Carbon, 8.8% Hydrogen, 52.0% Oxygen, and 0.1% Sulphur content. Meanwhile, the bio-char has a calorific value of 31 MJ/kg, with a fixed carbon content of 77.0%, volatile matter of 12.9% and ash content of 10.1%. Experiments with steel shots produced fine charcoal and coarse charcoal. The ash content of fine charcoal is 20.8%, greater than coarse charcoal by 6.9%, but coarse charcoal has a Carbon content of 80.7%, which is higher than fine charcoal by 68.2%. This causes the Higher Heating Value (HHV) of coarse charcoal of 30.8 MJ/kg to be greater than the HHV of fine charcoal of 25.7 MJ/kg. Those results are crucial, as those are the data needed to upgrade the pyrolysis oil into high-quality fuel and when processing the bio-char into carbon black, which is a high value-added material.
