UJI KARAKTERISTIK MINYAK PIROLISIS BERBAHAN BAKU LIMBAH PLASTIK POLYPROPYLENE

Abstract

The number of plastic uses that are not accompanied by the ability to recycle has effect an increase the amount of plastic on earth. Plastics have non-biodegradable properties. One safe method is pyrolysis which is an eco-friendly method because it does not produce waste during the  process. This method can also reduce waste by up to 90%. Pyrolysis produces  products in the form of charcoal (char), oil, and gas. Bio-oil from  pyrolysis can be used  as a substitute for fossil fuels. The purpose of this study  was to analyze the characteristics of oil produced by pyrolysis polypropylene plastic, the influence of reactor temperature on the characteristics of pyrolysis oil, and compare oil characteristics  with Other fuels include: density, viscostas,  heatvalue, flash point,and  cetane number.  This study uses experimental methods with descriptive qualitative data analysis, namely by applying reactors at temperatures of 350°C, 400°C, and  450°C to determine the characteristics of  pyrolysis oil, namely: density, viscosity,  flash point, heat value, and cetane number. The best pyrolysis oil characteristics obtain are density at reactor temperature of 400°C  which is 0.813 kg / l. Viscosity and heat values at reactor temperature 350°C which is 2.05 cst  and  12380.5 kcal/kg. Flash points and cetane numbers at reactor temperatures of 450°C  which is 51.05°C  and 47.05. The temperature of the reactor affects the characteristics of pyrolysis oil. From the results of the comparison it can be concluded that the characteristics of PP pyrolysis oil are close to the characteristics of diesel.
