Analisis Kuantitas dan Kualitas Minyak Hasil Pirolisis dari Jenis Plastik PP dan LDPE

Abstract

Plastic waste management is a problem because plastic is a material that cannot be decomposed naturally. Pyrolysis is one of the plastic waste processing methods to solve the problem of plastic waste volume by using chemical recycling methods. The purpose of this research is to determine the quantity and quality of density, viscosity and calorific value of pyrolyzed oil from Polypropylene (PP) and Low Density Polyethylene (LDPE) plastic types and compare them with oil on the market. This study used 15 kg each of Polypropylene (PP) and Low Density Polyethylene (LDPE) plastic waste. The pyrolysis process was carried out with a temperature range of 250-3500C. The quantity of PP plastic pyrolysis oil obtained was 12730 ml while the LDPE plastic type only amounted to 10490 ml, where the PP plastic type produced 21.3% more oil than the LDPE plastic type at the same treatment and temperature. The highest density for oil from pyrolysis of PP plastic is obtained at a temperature of 2500C which is 811 Kg/m3 and for the lowest density at a temperature of 3500C for the type of plastic PP lower density of 782 Kg/m3. The highest viscosity value of PP plastic type is at a temperature of 2500C, namely 2.02 cP and the lowest viscosity value at a temperature of 3500C, namely 0.86 cP. For the type of LDPE plastic, the highest viscosity is at a temperature of 3500C, namely 1.35 cP and the lowest viscosity at a temperature of 2500C, which is 1.14 cP. The highest calorific value of oil from pyrolysis of PP plastic at 3500C where the value is 10.870 kcal/g and the lowest calorific value at 2500C the calorific value of the oil obtained is 10.386 kcal/g.
