Abstract:
e husk is
count
ed as
an
agricultural waste that
results in
environmental problems
during
itshandling. In this
work
, rice husk was used as raw material for producing
liquid
biofuel
(pyrolysisoil)
via pyrolysis. The pyrolysis
reaction
was carried out at temperatures of 450, 500, and 550
°C
for 1 hour
.
The pyrolysis oil was collected and weighted for every 10 minutes. The results showedthat the increase in pyrolysis temperature caused the yield of pyrolysis oil to increase.
Theproperties in the term of heating value also increased while viscosity and density of pyrolysis oil
decreased. These properties were almost similar to diesel oil with a slightly lower heating value.The proposed model using the
single reaction model and two stages
model
were fit to representthe mechanism of rice husk pyrolysis reaction in this study. However, the results of two stagesmodel gave a lower error than those of the single reaction model. Furthermore,
the rate ofpyrolysis reaction
at various temperatures could be determined using
the
kinetic data obtainedfrom the developed model. This information would be useful for designing the pyrolysis reactorespecially
for producing biofuel
(pyrolysis oil)
from the rice husk.
