In this study, pyrolysis experiments on palm shell were performed
in a fixed-bed reactor under a nitrogen atmosphere.
The highest liquid yield (bio-oil) of 46.1 wt% was obtained at
a temperature of 500 C with a particle size of 1.7 < dp <2mm,
a reaction time of 60 min and a nitrogen flow rate of 2 L/min.
Bio-oil derived from palm shell was a mixture of various organic compounds of carbons (C3, C5, C6, C7, C8 and C9), with a lot of oxygenated aromatic (ArO).
However, it was noted that the bio-oil product contains a significant amount (53 wt%) of water, low pH (2.5) and high oxygen content (71.40 wt%).
FT-IR analysis also showed that the bio-oil compositions were dominated by oxygenated species. Obviously, the high oxygenated oils need to be upgraded in order to raise the
heating values before it can be for industrial fuels
