High energy fuel
production by
optimization of waste
polymers pyrolysis

Polymers are among the
most popular materials
used in modern societies. The
applications of polymers go from
high corrosion and temperature
long-lasting components to
one-time use applications
containers; such as those used
for food, beverages, liquids
and a number of products
consumed in our daily life. It
is estimated that worldwide,
more than 100millions of tons
of plastic are wasted every year
after one single use. Due to
its high stability, most of these
materials remain undegraded for
decades, polluting the land, air
and water with the consequent
negative impact on humans and
animal life. In recent years, an
alternative that has called the
attention is the use of pyrolytic
process to transform wasted
materials into fuels and other
chemicals compounds, as an
alternative to reduce the amount
of material disposed of and
at the same time, to generate
products of economic interest. In
this project, a pyrolytic process
was implemented in order to
thermally decompose High-
Density Polyethylene (HDPE) into
products with applications as
fuel with high energy content.
The HDPE was initially evaluated
in a Thermogravimetric analyzer
Q500, with this information the
pyrolytic reactor was adjusted at
600°C, at a heating rate of 20°C/
min and flow of 40mL/min of N 2.
25g of HDPE with a mean particle
size of 5mm were treated during
25minutes. After that, the
pyrolysis products were analyzed
by Fourier-Transform Infrared
Spectroscopy to determine
its higher heating value (HHV)
and the functional chemical
groups present. Additionally,
a second test was performed,
reducing the HDPE mass to 15g
and increasing the temperature
to 700°C. The obtained results
from the first test showed that
the products obtained have an
HHV of 47MJ/kg, which is an
encouraging finding, considering
the HHV of diesel and gasoline
are 45 and 44MJ/kg respectively.
With respect to the second
evaluation, the results proved
that an increase in the reaction
temperature decreases the
density of the products which
facilitates its manipulation and
application as high energy fuel.
