Catalytic Degradation of Used Plastics oil as Liquid Fuel for IC Engines

Abstract

Plastic pyrolysis oil (PPO) having the acceptable combustion lineaments and in addition, it can be used as alternative fuel for IC engines by blending together with diesel. In the research, used and disposed high-density polyethylene plastics such as plastic bottles, cans and bags have been used to extract the plastic oils from the self-developed pyrolysis reactor. Liquid oil from the plastic has been obtained by heating the waste used plastic in the reactor at 300–500 °C for ceaseless 2–3 hours in the fully locked environment. The obtained plastic hot gases as consequence, been cooled to acquire plastic pyrolysis oil in the liquid form. Further, the oil has been purified and blended along with the diesel in different propositions to conduct the trial experiments to observe the performances. The characteristics of the combustion experiments include emission and performance aspects. The attributes such as smoke density, NOx emission, CO emission, HC emission, CO2 emission as well as exhaust gas temperature and oxygen allocation have tested. The blends of diverse ratios have related and the plastic oil bearing substantial improvements.
