Palm EFB has high heating value and low greenhouse gas emissions during combustion.
Conversion of EFB to bio-oil is mainly by fast pyrolysis without and with catalyst.
Bio-oil from EFB is lower in heating value, heavier and more acidic than fuel oil.
The viscosity of bio-oil from EFB is between those of light and heavy fuel oils.
The flash and pour points of bio-oil from EFB are close to those of light fuel oil.
Abstract Empty fruit bunch (EFB) from oil palm is one of the potential biomass to produce biofuels like bio-oil due to its abundant supply and favorable physicochemical characteristics. Confirming the assertion, this paper presents an overview of EFB as a feedstock for bio-oil production. The fundamental characteristics of EFB in terms of proximate analysis, ultimate analysis and chemical composition, as well as the recent advances in EFB conversion processes for bio-oil production like pyrolysis and solvolysis are outlined and discussed. A comparison of properties in terms of proximate analysis, ultimate analysis and fuel properties between the bio-oil from EFB and petroleum fuel oil is included. The major challenges and future prospects towards the utilization of EFB as a useful resource for bio-oil production are also addressed. Keywords
