Abstract
Oil palm biomass generates an abundance via the oil palm industry such as Palm kernel shell (PKS), empty fruit bunch (EFB), frond, trunk.
Problem Statement: The main issue nowadays is global warming; one of the factors is the increment of CO2 content in the atmosphere. In order to reduce the CO2 content in the atmosphere, biomass is used, as it is a renewable, sustainable, and cost-effective alternative energy source that needs to be adopted in the energy mix. The objective of this study was to improve the quality of bio-oil.
Approach: In this research, an empty fruit bunch (EFB) was utilized in a fixed bed reactor, and pyrolysis oil was upgraded via a thermal distillation reactor. The temperature of pyrolysis was 500 °C, and the temperature of thermal distillation was 100 °C. Gas chromatography-mass spectroscopic and ultimate analysis was utilized to investigate chemical composition.
Results: The maximum distilled bio-oil yield was 60- 65 % at 100 °C. The heating value of bio-oil was 21 MJ/kg, and distilled bio-oil was 30 MJ/kg. The density of bio-oil was 1035 g/mL, and distilled bio-oil was 980 g/mL
Conclusion: The results showed that the distilled bio-oil obtained from EFB bio-oil has a high heating value low oxygen content than it can use as fuel in engines.
