Biodiesel
is
one
of
the
renewable
and
clean
burning
fuels,
which
can
be
used
in
diesel
engines.
Biodiesel
is
usually
generated
from
food-grade
vegetable
oils
using
transesterification
process.
Using
the
food-grade
vegetable
oils
is
not
economical
since
they
are
more
expensive
than
diesel
fuel.
Therefore,
it
is
said
that
the
main
obstacle
for
commercialization
of
biodiesel
is
its
high
cost.
The
kind
of
feedstock,
which
is
used
is
the
most
effective
factor
on
the
biodiesel
characteristics
and
the
price.
So,
at
first
finding
a
proper
feedstock
has
an
important
role
in
different
places.
Therefore
in
this
research
the
possibility
of
using
date
seed
as
a
cheap
feedstock
for
biodiesel
production
was
investigated,
because
it
is
produced
largely
in
the
hot
arid
regions
of southwestern
Asia
and
northern
Africa.
After
extracting
oil
and
producing
biodiesel
from
Phoenix
dactylifera
(date
seed)
oil,
the
properties
of biodiesel
were
evaluated
by
fuel
standard
tests
and
the
results
were
compared
with
EN14214
and
ASTM
D6751
standards
and
also
compared
with
the
properties
of
produced.
According
to
the
results,
the
important
benefit
of
the
biodiesel
from
the
date
seed
oil
is high
cetane
number
(60.3),
low
iodine
value
(46),
viscosity
(3.84
mm2/s)
and
flash
point
(140◦C)
and
the
only
weak
point
is
its
high
pouring
point
(−1◦C)
which
limits
the
use
of date
seed
biodiesel
in
cold
weather
in
comparison
with
other
vegetable
biodiesel
fuels.
