Investigation on Pyrolysis of Plastic Waste to Fuel Oil

摘要

Growing demand for the energy promotes the research for alternate fuels. Energy can be generated from different sources like solar, wind, biomass, etc. In this work an effort has been made to convert the waste plastics into a useful source of energy. Pyrolysis is one form of thermo chemical conversion in the absence of air. In this work pyrolysis of High Density Poly Ethylene (HDPE) & Polypropylene has been carried out. Waste plastics were collected from nearby sources and were cut into small pieces. It was subjected to thermal decomposition in a laboratory scale pyrolysis set up at a temperature range of 300-500°C and at atmospheric pressure. The volatile matter which comes out of the reactor was condensed to obtain pyrolytic oil. The various properties of the products obtained were then tested and compared with the actual values for petroleum oil. In order to improve the yield of the pyrolytic oil, Nickel nano particles and Nickel oxide nano particles were added as a catalyst along with the plastic wastes. It was found that the yield was improved significantly in the presence of catalyst.
