Abstract
The composition of fuel production per litre from polyethylene waste via pyrolysis was determined through thermal degradation. Compositions of fuels from high density polyethylene/low density polyethylene (HDPE/LDPE) pyrolysis were naphta, gasoline, and active carbon as residues. The pyrolysis process was carried out at 450-621°C without any catalyst and quantitative analysis method was conducted by using GC-MS. The product of 5 kg pyrolysis HDPE are 3.25 litres of naphta; 0.85 litre of gasoline; 0.325 litre of diesel fuel; and 18.06 grams of active carbon. Then the product of 5 kg pyrolysis LDPE are 0.5 litres of naphta; 2.9 litres of gasoline; 0,1 litre of diesel fuel; and 19 grams of active carbon.
Highlights
The production fuels from plastic waste has been widely reported by many researchers
The relationship between production of fuels from high density polyethylene (HDPE) and low density polyethylene (LDPE) plastic wastes via pyrolysis methods has been an active research area would be explained in detail at theory and methodology
The C5-C12 chain is classified as gasoline, C10-C18 is classified as kerosene, > C12 is classified as diesel oil, and C20-C50 is classified as oil [9]
Summary
Cleaned and chopped HDPE and LDPE plastic samples of 5 kg each were put into the reactor. The plastic is heated using the pyrolysis method at temperature of. 450-621°C without any catalyst for 4 hours for HDPE and 3 hours for LDPE. The gas produced from the reactor were condensed into a liquid phase using a condenser. The product conversion calculation produced is used as follows: Liquid Products (L/Kg %) = (Litre of product/Mass of raw material) x 100%. Solid Product or Residue (Kg/Kg %) = (Kg of product Mass of raw material) x 100%. Products from plastic pyrolysis in the form of naphtha, gasoline, and diesel fuel and produced residues (activated carbon) were analyzed by GC-MS at the Diponegoro University Integrated Laboratory
