In this work palm shell waste was pyrolyzed to produces bio-oil. The effects of several
parameters on the pyrolysis efficiency were tested to identify the optimal bio-oil production
conditions. The tested parameters include temperature, N2 flow rate, feed-stock
particle size, and reaction time. The experiments were conducted using a fix-bed reactor.
The efficient response surface methodology (RSM), with a central composite design (CCD),
were used for modeling and optimization the process parameters. The results showed that
the second-order polynomial equation explains adequately the non-linear nature of the
modeled response. An R2 value of 0.9337 indicates a sufficient adjustment of the model
with the experimental data. The optimal conditions found to be at the temperature of
500 C, N2 flow rate of 2 L/min, particle size of 2 mm and reaction time of 60 min and yield
of bio-oil was approximately obtained 46.4 wt %. In addition, Fourier Transform infra-red
(FT-IR) spectroscopy and gas chromatography/mass spectrometry (GCeMS) were used to
characterize the gained bio-oil under the optimum condition.
