| Summary: | This study aimed to produce
and improve the quality of pyrolysis oil as a source of bioenergy that is made
by mixing palm empty fruit bunch (EFB) with high-density polyethylene (HDPE)
plastic waste. The slow co-pyrolysis method was employed, and HDPE waste and
EFB were fed into the pyrolysis reactor at HDPE amounts of 0, 10, 25, 50, 75,
and 100% by weight. The pyrolysis oil product was obtained by co-firing EFB
with HDPE using the slow co-pyrolysis method in a fixed bed reactor at 500°C with a flow rate of 750 mL/min and a heating rate of
5°C/min. The chemical compositions
of pyrolysis oil were analyzed by gas chromatography-mass spectroscopy. A
pyrolysis oil produced by HDPE 100 wt.% was dominated by the chemical compounds
of phenols, aromatics, aliphatic, and acids, while for EFB 100 wt.% was
dominated with aldehydes, acids, phenols, furan and aliphatic. The addition of
HDPE reduced the amount of pyrolysis oil yield, increased the pH, reduced the
viscosity, and reduced the oxygen content of the pyrolysis oil. These results
proved that the HDPE affected the decrease in pyrolysis oil and the increase in
gas production from co-firing HDPE and EFB using the slow co-pyrolysis method. |
