THE COMPARISON OF PROPERTIES OF PYROLYSIS OIL FROM POLYPROPELENE PLASTIC WASTE AT LOW HEATING RATE WITH INDONESIAN DIESEL OIL

Abstract

Polypropylene plastic waste is naturally not easily degraded, causing a negative impact on the environment. The pirolisis method is one method that can overcome this problem, besides that there is added value in the form of oil from pirolisis. The current research aims to see the characteristics of oil from pirolisis of polypropylene plastic waste at low heating rates, namely at pirolisis temperatures of 350 0C, 400 0C and 450 0C. The characteristics tested are density by ASTM D-1298 method, kinematic viscosity by ASTM D-445 method, Flash point by ASTM D-93 method, Calorific value by ASTM D-240 method, Cetane number by ASTM D-613 method and color by ASTM D-1500 method. The characteristics of oil from pirolisis of Polypropylene plastic waste are then compared with the quality standards of diesel fuel based on Decree of the Director General of Oil and Gas No. 146.K/10/DJM/2020. The results showed that the characteristics of oil from pirolisis of polypropylene plastic waste were close to the quality standards of diesel fuel 48 with density in the range of 0.805-0.882, kinematic viscosity in the range of 2.05- 2.28 Cts, 05-0.882, flash point in the range of 46.5 - 51.05 0C, calorific value in the range of 11480-12380 kcal/kg, Cetane number in the range of 44.8-47.05 and color of oil in scale No. 0.5.
