Abstract
Pyrolysis is one of the effective ways to convert biomass into energy and value added products. Till date, no comparative study has been done on the characteristic of bio-oils of oil palm shell (OPS) and empty fruit bunch (EFB) from various fast pyrolysis techniques. This includes fluidized bed, fixed bed, rotating cone, microwave and others. Thus, the main objective of this paper was to analyze the characteristics of OPS and EFB bio-oils obtained from these processing techniques. Temperature was found to be the key parameter for the quality of bio-oils. Besides the various pyrolysis techniques, the lignocellulosic constituents of oil palm biomass also influence the chemical composition of the bio-oils. Overall, chemical analysis of OPS and EFB bio-oil through GC-MS has shown variation in the amount of phenol and its derivatives.
