Oil palm shell and empty fruit bunch (EFB) are biomass which contains lignocellulose which can potentially converted to bio-oil (liquid product of pyrolysis). Pyrolysis process produces solid, liquid and gas products. Temperature level of pyrolysis process influences bio-oil composition and its characteristics. The objective of this research was to characterize bio-oil of pyrolysis product on palm oil shell and empty fruit bunch at 3 different temperature levels. Pyrolysis process was done by using mini pyrolysis reactor. The temperature was set at 400°C, 500°C and 600°C. The result showed that mass fraction of palm oil shell was fluctuating along with the temperature difference. Shell solid fraction was decreasing at range 44.27-34.99% while shell liquid and gas fraction were increasing at range 38.33-43.28% and 17.40-21.73%, respectively. EFB products mass fraction was fluctuating at range 30.66-45.28%, 24.85-29.16% and 28.86-44.49% for solid, liquid and gas respectively. The highest shell bio-oil calorific value was 36.15 kJ/g at temperature 500°C and EFB highest bio-oil calorific value was 40.86 kJ/g at temperature 600°C. The highest shell and EFB bio-oil energy was 7,445.39 kJ and 1117.62 kJ.
