Performance and emission characteristics of diesel fuel produced from waste plastic oil obtained by catalytic pyrolysis of waste polypropylene

Waste plastic oil derived from kaoline catalyzed pyrolysis of waste polypropylene is blended with diesel fuel, tested as an alternative fuel in a diesel engine, and its performance characteristics are analyzed and compared with diesel fuel operation. It is observed that the engine could operate with maximum 50% waste plastic oil blended diesel. An engine showed better performance up to 30% blend, but beyond 50% blend it gave a vibration. The results showed a stable performance with brake thermal efficiency similar to that of diesel and its value is higher up to 80% of full load. All emissions are considerably higher than that of the diesel baseline especially at high load and blend.
