Selection of Optimum Blend of Waste Plastic Oil-Diesel Blends Adapting Combinatorial Mathematics Based Approach 2018-28-0018
In order to compensate energy demand while with replacement of fossil fuels at least to some extent, the development of alternative energy sources is evitable. Global warming and waste management policies have forced for the use of alternative fuels on engines. The production of fuel from plastic wastes will indeed tackle the environmental pollution problem of waste plastic management in the landfills. Plastics being derived from petrochemical source has higher amount of hydrocarbon which yield oil with high calorific value. Engine tests have been carried out using neat waste plastic oil and blends of waste plastic oil in proportions of 25%, 50%, and 75% with diesel as fuel. Combinatorial mathematics based approach has been adapted to choose the optimum blend for superior performance of the engine. Carbon hydrogen nitrogen sulphur analysis of waste plastic oil blends reveals that the amount of oxygen increases with increase in waste plastic oil percentage in blends. Results of combinatorial mathematics based approach and experimental tests showed that 25% of waste plastic oil with diesel is optimum blend.
