Energy, exergy, sustainability evaluation of the usage of pyrolytic oil and conventional fuels in diesel engines

Solid wastes like used tires have high annual production and significant environmental impact potential. Tire wastes can be pyrolyzed to regenerate energy and create useful products. The purpose of this study is to demonstrate the use of pyrolytic oil produced by the pyrolysis of waste tires as fuel in diesel engines. The energy exergy and sustainability of pyrolytic oil and conventional marine diesel fuels were examined in this study. The energy was determined in the experimental processes used to transform used tires into carbon black, pyrolytic oil, and pyrolytic gas. The components of SOX, NOX, and CO2 produced when pyrolytic oil and conventional marine fuels were combusted in diesel engines were obtained. As a result of the study, the energy value of the pyrolytic oil produced during the pyrolysis process as fuel was determined to be 2.8 MW. The results indicated that the combustion of pyrolytic oil in diesel engines had a thermal efficiency of 38% and a second-law efficiency of 58%. The standard marine fuels were found to have a sustainability index of 2.7, while pyrolytic oil had a sustainability index of 1.42.

Automated summary

This study examines the feasibility of using pyrolytic oil from waste tires as fuel in diesel engines, and evaluates its energy, exergy, and sustainability. The results indicate that pyrolytic oil has potential as a renewable fuel source with relatively high thermal efficiency.
