Abstract:A novel nanofuel is formulated using aluminum oxide (alumina) nanoparticles (AONs) in neat plastic oil (PO). A light-duty compression-ignition engine is used in the present investigation to analyze the effect of a 100% plastic nanofuel under different concentrations of nanoparticle on performance, combustion, and emission characteristics. The modified fuels used for conducting the experiment were formulated by mixing PO with 100, 150, and 200 mg/L of AON. The results of the physical and chemical properties of … Show more
“…In a similar approach, nanofuels containing Al 2 O 3 nanoparticles in pyrolysis oil were combusted in a lightduty compression-ignition engine at different concentrations of nanoparticles (100−200 ppm). 295 At 200 ppm nanoparticle concentration, lower in-cylinder pressure, delay period, and combustion duration were observed compared to neat pyrolysis oil. Thermal efficiency was comparable and gaseous emissions were reduced, which was even lower than diesel.…”

The increasing demand for plastics for their widespread applications has ultimately resulted in accumulation of substantial plastic waste, which remains a concern due to limited efforts, inadequacy, and environmental distresses of conventional techniques for waste plastics remediation. The enhanced production of raw materials for polymer syntheses has a dual impact on our ecosystem by causing rapid depletion of nonrenewable petroleum resources and waste generation. To address this situation, researchers have adopted advanced thermochemical recycling processes to produce intermediate products of the petrochemical industries including monomers, fuels, and other value-added products. Such practices can potentially serve the purpose of a circular economy. This review aims to cover the recent highlights in the field of waste plastics pyrolysis including critical observations from the past to provide precise understanding. Consequently, the reactivities and product distributions for plastic feeds, pyrolysis reactors, roles of catalysts, and effects of operating parameters on reactivity and selectivity have been covered. Coprocessing of plastic waste with radioactive materials, biomass, and heavy petroleum residue is also discussed. Furthermore, an overview on kinetics and mechanistic aspects of plastic pyrolysis is presented with a discussion on relevant analytical techniques. The applications of pyrolysis oil as a fuel or fuel additive are comprised in a separate section. Lastly, comparisons of existing chemical recycling technologies, summaries of commercial operations, and future projections are provided.

“…This mixture represents an interesting alternative to standard fuel. In study [24], the authors examined the performance of a CI engine using fuel derived from plastic with the addition of aluminum oxide nanoparticles in proportions of 100, 150, and 200 mg/L. The analysis showed that the addition of aluminum oxide shortens the autoignition delay period.…”
This article discusses the potential applications of the Fuel Shot liquid catalyst in compression ignition (CI) engines for reducing toxic substances in exhaust gases. Incorporating catalysts into fuel can optimize the combustion process, consequently reducing the emission of toxic substances into the atmosphere. Toxic compounds, such as nitrogen oxides, particulate matter, and hydrocarbons, adversely affect flora and fauna. Various methods are known for reducing their concentration in engine exhaust gases, one of which is the Fuel Shot liquid catalyst. The authors conducted experiments on a Fiat 1.3 JTD engine with a Common Rail system. The results indicate that the application of the liquid catalyst reduces the content of nitrogen oxides and hydrocarbons in the exhaust gases and slightly decreases fuel consumption. Additionally, investigations were carried out on the engine’s injection apparatus, which was fueled with modified fuel. The findings demonstrate that the fuel additive does not affect the wear of precision parts of fuel injectors and high-pressure pumps.
