Pyrolysis of disposed plastic food containers and its potential in diesel engine by doping with nano particle at optimum injection timing

Abstract

The excess consumption of plastics and improper waste management leads us to remove the plastic leftovers collected in landfills is basic from the ecological point of view. The conversion of waste into energy is an attempt that was made to assess the energy exemplified from waste plastic food containers could be recuperated as waste plastic oil (WPO) through pyrolysis. In order to maximise the potential of WPO as a fuel for diesel motors, Titanium dioxide (TiO2) nanoparticle was doped at three levels. This article focuses on the effect of nanoparticle doped WPO on diesel engine characteristics at three different fuel injection timings 25°BTDC (Before Top Dead Center), 23°BTDC, 21°BTDC. The test results displayed a greater improvement in brake specific fuel consumption and brake thermal efficiency for TiO2 nanoparticles blended test fuels when compared to other test blends by advancing the injection timing by two degrees. The significant reduction in pollutants such as carbon monoxide, hydrocarbons and smoke were recorded due to improved oxidation rate by TiO2 nanoparticle, however punished with little NOx. The study led to the decision that adding 150 ppm of TiO2 with WPO would be the decent substitute for diesel for the engines that are operated under 25°BTDC.
