Pyrolysis of Waste Plastic and use of Plastic Oil as an Alternate Fuel in Diesel Engine
Nagaraj Shivakumar Biradar , Dr. Omprakash Hebbal
Plastic is versatile, light weight, moisture, resistance strong, and relatively inexpensive. This inherent quality of the plastic made it an integral part of daily life and as a result of which polymer products becoming massive scale worldwide. On an average 110 million tonnes of plastic is produced per year globally. Among this India produces 14088 KTA thermoplastic in a year. About 70% of plastic products after use converted into waste in a short span. Approximately 9.4 million tonnes per TPA generated in a country which 26000 TPD. A proper plastic management system shall be developed to mitigate problems arising.
80% of plastic is recycled and remaining indispensable. These waste plastic is pyrolated to convert into useful liquid fuel. In the present study an attempt is made to convert waste polyethylene milk pouches into oil in a batch reactor. The oil is characterized and found that suitable to use as a fuel in diesel engine, due to favourable properties of plastic oil it is mixed with diesel at 10%, 20% and 30% by volume basics. This blend is used to run a single cylinder diesel engine and to evaluate combustion, emission and performances characteristics. The yield of plastic oil is higher for 460 o C i.e. 784 grams/kg. It is found that brake thermal efficiency of plastic oil blend with diesel is having higher than that of neat
diesel. Further as the percentage of plastic oil in the diesel increases the brake thermal efficiency also increases. However emissions of the NO X for the blends are higher than that of neat diesel and this attributes to oxygen molecule availability in plastic oil.
