Empty fruit bunches (EFB) are palm oil processing waste consisting of fibers and skins that still contain oil. EFB can be used as fuel for power plants or in the pyrolysis process to produce bio-oil, biogas and biochar. The test results showed various chemical contents of EFB and functional groups such as hydrocarbons, alcohols, aldehydes, acids, hydroxyl, carboxylates, ketones, chlorides, nitrates, nitriles, amines, phenols, hydrogen sulfide, sulfur and oxygen. The calorific value of EFB varies between 4,000 - 4,400 kcal or 16.6 - 18.48 kJ per metric ton. Pyrolysis at 400oC produces compounds with aliphatic and acyclic hydrocarbon groups, as well as a higher methane content.
