| Summary: | Plastic wastes have considerable potential to be converted into alternative
fuels through pyrolysis process and reduce negative impacts on the environment
pollution. Plastic pyrolysis process carried out to obtain hydrocarbon compounds
that can be used as fuel and increase the economic value of the plastic wastes. The
raw material used is Low Density Polyethylene (LDPE). This study was
conducted to determine the effect of variations in the mass of catalyst on the
characteristics and applications of waste plastics pyrolysis oil (WPO). The reactor
used was a batch-type fixed with a temperature of 450 º C, nitrogen flow rate of
0.8 l / min, which feedstock used is 2000 g and natural zeolite as a catalyst. The
use of mass variation of Catalyst Feedstock Ratio (CFR) are 0.05, 0.10 and 0.15.
The results showed that the increasing use of the mass of catalyst have an effect in
decreasing of liquid products. Most liquid products obtained in the use of 100 g
catalyst, with a percentage of 56.75%wt liquid products, 38.60%wt gas products
and 4.65%wt solid products. The results of the characteristics and properties
testing of plastics pyrolysis oils include specific gravity, kinematic viscosity, flash
point, pour point, cloud point, water content, ash content, carbon number
distribution and PONA analysis showed that the pyrolysis oil has similarities with
the kerosene and can be developed as an alternative fuels. Plastic pyrolysis oil is
then applied to the pressurized oil stove and tested using the Water Boiling Test
(WBT). Power generated on stove testing ranges from 0.83 kW-1,13 kW and the
thermal efficiency 29.85% to 54.89%. The test results showed that the pyrolysis
oil can be applied on the pressurized oil stove and the best mixture is at 25%
WPO and 75% kerosene.
