Abstract

This study was aimed to examine the utilization of incenerator heat for pyrolysis process. This research used an integrated incinerator-pyrolysis reactor with laboratory scale. The pyrolysis reactor was located in the an incinerator chamber. The dimensions of the pyrolysis chamber was 15 cm x 15 cm x 25 cm, and the dimensions of the incinerator chamber was 45 cm x 45 cm x 50 cm. Pyrolysis process used PP, PET and HDPE plastic, with the treatment of each type of plastic weighing 300 g. incinerator and pyrolysis chambers were equipped with type K thermocouple. The test parameters in this study were incinerator combustion temperatures, pyrolysis combustion temperature and pyrolysis product. The testing time was 120 minutes. The results of this study were incinerator combustion chamber temperatures fluctuating with the highest combustion chamber temperature was 739.4 0C and the highest temperature in the pyrolysis combustion chamber was 433.3 0C. The resulting pyrolysis products were oil, gas and char. The results of PP pyrolysis are 70.3% oil, 29.7% gas, and 0% char. PET pyrolysis results were 77.3% gas, 16% char and 6.7% oil.
