“…The fuel trials using blends in conventional engines reveal a stable performance with less emission of NOx and SOx compared to diesel and gasoline fuels [ 65 ]. A reduced specific fuel consumption has also been reported [ 61 ]. Awasthi and Gaikwad [ 66 ] stated that the overall performance of the blend of diesel and plastic oil in a single cylinder four stroke VCR diesel engine was very satisfactory, particularly with 20 wt.% of pyrolysis plastic oil.…”

“…The comparison between diesel fuel and a sample plastic oil obtained from the pyrolysis of mixed plastics, including 58 wt.% of HDPE and LDPE, 27 wt.% of PP, 9 wt.% of PS, 5 wt.% of PET [ 61 ] is shown in Table 7 . The GC-MS results reveal that the carbon number distributions of the produced plastic oil is as follows: 35.41 wt.% of C6–C9, 48.40 wt.% of C10–C14, 13.21 wt.% of C15–C20, and 1.83 wt.% of C20+ [ 61 ]. The comparison between fuel properties of pyrolysis plastic oil and diesel indicates similar heating values and kinematic viscosity, while the plastic oil has a higher ash content and a lower cetane number compared to diesel fuel.…”

“…In contrast, there are several researchers [ 8 , 62 , 63 , 64 ] who believe improvements in plastic oil quality are needed to meet EN590 standards. In terms of drawbacks associated with the utilization of pyrolysis plastic oil in internal combustion engines, a high heat release and delayed ignition have been reported [ 61 ]. As such, a blend of conventional fuel and plastic oil can be a potential solution.…”

Pyrolytic Conversion of Plastic Waste to Value-Added Products and Fuels: A Review

Plastic production has been rapidly growing across the world and, at the end of their use, many of the plastic products become waste disposed of in landfills or dispersed, causing serious environmental and health issues. From a sustainability point of view, the conversion of plastic waste to fuels or, better yet, to individual monomers, leads to a much greener waste management compared to landfill disposal. In this paper, we systematically review the potential of pyrolysis as an effective thermochemical conversion method for the valorization of plastic waste. Different pyrolysis types, along with the influence of operating conditions, e.g., catalyst types, temperature, vapor residence time, and plastic waste types, on yields, quality, and applications of the cracking plastic products are discussed. The quality of pyrolysis plastic oil, before and after upgrading, is compared to conventional diesel fuel. Plastic oil yields as high as 95 wt.% can be achieved through slow pyrolysis. Plastic oil has a heating value approximately equivalent to that of diesel fuel, i.e., 45 MJ/kg, no sulfur, a very low water and ash content, and an almost neutral pH, making it a promising alternative to conventional petroleum-based fuels. This oil, as-is or after minor modifications, can be readily used in conventional diesel engines. Fast pyrolysis mainly produces wax rather than oil. However, in the presence of a suitable catalyst, waxy products further crack into oil. Wax is an intermediate feedstock and can be used in fluid catalytic cracking (FCC) units to produce fuel or other valuable petrochemical products. Flash pyrolysis of plastic waste, performed at high temperatures, i.e., near 1000 °C, and with very short vapor residence times, i.e., less than 250 ms, can recover up to 50 wt.% ethylene monomers from polyethylene waste. Alternatively, pyrolytic conversion of plastic waste to olefins can be performed in two stages, with the conversion of plastic waste to plastic oil, followed by thermal cracking of oil to monomers in a second stage. The conversion of plastic waste to carbon nanotubes, representing a higher-value product than fuel, is also discussed in detail. The results indicate that up to 25 wt.% of waste plastic can be converted into carbon nanotubes.

“…It clearly shows that heavier carbon compounds are very low and also higher concentrations of aromatic compounds are found. 31 It also consists of 4.53% oxygenated compounds such as furan, acetyl cyclopentane, and 2-ethyl-2-methyl-2-hepten-4-one that are found in the analysis. The compounds present in neat ULDP oil are similar to diesel fuel.…”

“…There are also many non‐bio based papers for alternative fuels. Alternative fuels obtained as a result of pyrolysis of the waste tire 11,12 or waste plastic 13‐15 can be mixed with diesel or biodiesel. Besides, waste transformer oils 16,17 and waste lubricating oils 18,19 have also been reported to be used as fuels in diesel engines.…”

Today, there is an effort to obtain energy from every possible source and waste to meet the oil demand. Waste engine oil is one of them. Although waste lubricating oils have an important economic potential, the environmental effect of these oils is much more important than their economic effect. In this study, various waste engine oil‐diesel mixture (0:100, 10:90, 20:80, and 30:70) and various fuel pressure conditions (195–255 bar) experiments were performed for various engine loads (3–12 Nm) in a DI diesel power generator. It was aimed to increase the potential of using waste engine oil as fuel by adding 16 μmol/L Mn additive to the waste engine oil. For the design of the experiment, 1/8 fractional factorial Taguchi method was applied and the relationship between engine load, waste engine oil, fuel injection pressure and Mn additive with experimental factors has been successfully determined with variance analysis. Using regression analysis, regression equations were obtained for exhaust temperature, specific fuel consumption, light absorption coefficient, and nitrogen oxides. Finally, although waste engine oil causes deterioration on engine performance and emissions, it has been determined that the use of waste engine oil as fuel can be improved thanks to the Mn additive.
