“…However, the boiling temperature for each distillate volume value for the BCTO was a bit high in comparison with that of diesel. Higher distillation temperature is an advantage in view of improving of combustion efficiency leading to better motor performance [19,20]. Conversely, the distillate temperatures of T 10 , T 50 , and T 90 , respectively, were 198, 280, and 318 C for diesel in this study and also these parameter values were 294, 332, and 355 C for the BCTO oil, respectively.…”

In this study, the main target was to obtain the liquid fuel‐like product from the catalytic cracking of the used transformer oil over bentonite as a low‐cost catalyst. For this aim, a series of cracking runs were performed under certain experimental conditions (450 °C cracking temperature, 10 °C/min of heating rate, and catalyst in the range of 0–8.0 wt %) in a fixed‐bed reactor. In catalytic cracking runs, the use of bentonite as a catalyst led to a considerable increase in yield of the cracking oil comparable to that of the noncatalytic oil. The highest yield value of 98.64 wt % was achieved at catalyst ratio of 4.0 wt %. Furthermore, the liquid product obtained in the highest yield was characterized by FTIR and GC–MS to evaluate its composition in terms of compound distributions as a comparison with the noncatalytic run. Also, its fuel properties such as cetane index, higher heating value, viscosity, density, water content, elemental content, and so forth were analyzed using standard test techniques. Based on these results obtained, the catalytic liquid product can be utilized to prepare liquid fuel blends with diesel for the diesel engines. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13080, 2019

“…The presence of kerosene did not alter the density of diesel appreciably and hence density test for adulteration with kerosene is not useful. The observed variation in opacity with different proportions of adulterant although not sharp, showed a decreasing trend with increasing adulterant presence in diesel (Maceiras et al, 2017). However, the correlation coefficient (R 2 ) was 0.9985 and analyses of variance gave a Pr > F <0.0001.…”

“…The density of mixtures became stable at 40:60 (%) mixture with a value of 830 kg/m 3 . Irrespective of the level of adulteration performed within the mixtures range of 95:5 to 40:60 (%), they all met the Standard of density required in diesel fuel which is in the range of 830-880 kg/m 3 (UNE- EN ISO 3838,2004;Maceiras et al, 2017). However, the adulterated diesel lost its usefulness completely at the mixtures range of 35:65 to 0: 100(%) (Diesel: kerosene).…”

This research was carried out to estimate the proportional mixtures of diesel and kerosene that easily shows the incidence of fuel adulteration. Two samples (kerosene and diesel) were obtained from a base stock at Tema Oil Refinery and the purity for both the kerosene and diesel were ensured by testing their density, kinematic viscosity, distillation and flash point. The values obtained for these parameters after the analyses carried out are density at 15°C falls within 816-850 kgm 3 ; the flashpoint was found to be within 48-73°C; distillation at 360 °C were in the range of 96-98°C and kinematic viscosity at 37.8 °C were also in the range 1.5-3.5 mm 2 /s. The parameters analysed are good indicators in the assessment of the extent to which diesel fuel can be adulterated by kerosene. The above parameters were analysed using both standard American Society for Testing and Materials (ASTM) methods and Statistical Package for the Social Sciences (SPSS) version 23 statistical tools. The values obtained from the experiments conform to respective standards of United States Environmental Protection Agency (USEPA) regulations at 40CFR 79, 2017 and other literature values. The correlation coefficient (R 2) obtained after statistical analyses are 0.9984 for flash point, 0.9985 for density, 0.9405 for distillation and 0.9962 for kinematic viscosity. Also, analyses of variance (ANOVA) was Pr > F <0.0001 for all the parameters. However, the F calculated for various parameters are 669.3500 for flash point, 693.7294 for density, 16.6000 for distillation and 272.3459 for kinematic viscosity. This shows that the various parameters play a significant role in the adulteration of diesel fuel.

“…The effects of organic-based metal additives on engine performance and emissions have been observed in previous studies for biodiesel fuels derived from engine oils and different vegetable and animal oils in previous studies [29][30][31][32][33][34][35][42][43][44]. However, studies on waste mineral oils have focused on the recycling of waste mineral oils after different chemical and mechanical processes [15,[22][23][24][25]. It is known that the organic-based metal additives synthesized from metal oxides are the effect of improving the properties of fuels used in diesel engines.…”

“…Maceiras et al have converted fuels by pyrolytic distillation in the presence of sodium hydroxide and sodium carbonate catalyst, which can be used in waste engine oil diesel engines. With this study, it has been found that the conversion of waste engine oil to diesel fuel can be achieved by pyrolytic distillation in the presence of 2% sodium carbonate [22]. In their study, Prabakaran and colleagues examined the physical and thermal properties of waste engine oil reformed in acetic acid and clay compartments by diesel fuel at various ratios.…”

The heat values of waste mineral oils are equal to the heat value of the fuel oil. However, heat value alone is not sufficient for the use of waste minerals oils as fuel. However, the critical physical properties of fuels such as density and viscosity need to be adapted to the system in order to be used. In this study, the engine oils used in the first 10,000 km of the vehicles were used as waste mineral oil. An organic-based Mn additive was synthesized to improve the properties of the waste mineral oil. It was observed that mixing the Mn additive with the waste mineral oil at different doses (4, 8, 12, and 16 ppm) improves the viscosity of the waste oil and the flash point. The resulting fuel was evaluated for emission using different loads in a 5 kW capacity generator to compare the fuel with standard diesel fuel and to determine the effect of Mn addition. In the experimental study, it was observed that the emission characteristics of the fuel obtained from waste mineral oil were worse than diesel fuel, but some improvement was observed with Mn addition. As a result, we found that the use of waste mineral oils in engines in fuel standards was not appropriate, but may be improved with additives.
