“…[27] According to several researchers' predictions in the most recent literature on producing biodiesel, methyl esters derived from nonedible oils are indeed the best that require no engine modifications. [28][29][30] Not much evidence of studies relating to oil extraction from JFME pods (seeds) exists. Research into squeezing oil out of JFME seeds (pods) is lacking.…”

Biomass‐based biofuel production is a promising solution to the decline of fossil fuels. Prosopis juliflora seed‐derived vegetable oil, known as Prosopis juliflora methyl ester (JFME), offers a potential feedstock for biodiesel. To enhance its properties, the addition of Decanol is investigated, a higher‐order alcohol similar to Diesel. Experiments are conducted on a 5.2 kW compression ignition (CI) engine using JFME blended with different decanol concentrations (5%, 10%, 15%, and 20%). Fourier‐transform infrared spectroscopy and gas chromatography‐mass spectrometry analysis confirm its compliance with fuel standards. The findings reveal that the 20% decanol blend (D20) achieves a brake thermal efficiency of 29.9% at full load, with reduced NO, smoke, and hydrocarbon (HC) emissions compared to diesel. D20 shows NO emissions of 1265 ppm, smoke opacity of 53%, and HC emissions of 69 ppm, while diesel records 1320 ppm, 69%, and 75 ppm, respectively. The CO emissions for D20 are 0.359 vol%, slightly higher due to decanol's higher latent heat of evaporation. Moreover, D20 exhibits improved combustion with a higher mass fraction burnt and faster heat release rates. These results indicate the potential of using JFME blended with 20% decanol as an alternative fuel for CI engines, offering higher performance and reduced emissions.

“…Furthermore, LC-4, an obligate pMMOexpressing methanotroph, is expected to produce extensive intracytoplasmic membranes (ICM) to host this membrane-associated protein [23]. These membrane lipids are phospholipids containing C 14 -C 18 saturated and monounsaturated fatty acids and are suitable for use in biodiesel [22,24]. The present study explores biodiesel as a by-product of methane mitigation by Methylosarcina sp.…”

The conversion of methane into liquid biofuels using methane-consuming bacteria, known as methanotrophs, contributes to sustainable development, as it mitigates the problem of climate change caused by greenhouse gases and aids in producing cleaner and renewable energy. In the present research, an efficient methanotroph, Methylosarcina sp. LC-4, was studied as a prospective organism for biodiesel production using methane. The methane uptake rate by the organism was enhanced 1.6 times and 2.35 times by supplementing LC-4 with micronutrients, such as copper and tungstate, respectively. This unique ability of the isolated organism enables the deployment of methanotrophs-based processes in various industrial applications. A Plackett–Burman statistical (PBD) design was used to quantify the role of the micronutrients and other media components present in the nitrate minimal salt media (NMS) in biomass and fatty acid methyl esters (FAME) yields. Nitrate, phosphate, and tungstate had a positive effect, whereas copper, magnesium, and salinity had a negative effect. The modified NMS media, formulated according to the results from the PBD analysis, increased the FAME yield (mg/L) by 85.7%, with the FAME content of 13 ± 1% (w/w) among the highest reported in methanotrophs. The obtained FAME consisted majorly (~90%) of C14–C18 saturated and monounsaturated fatty acids, making it suitable for use as biodiesel.

Developments in Biodiesel

The increasing need for energy and the non-renewability of conventional diesel have led researchers to turn their attention to the development of alternative fuels. In this context, biodiesel and alcohols have gained recognition as promising oxygenated alternative fuel additives that can be used in modern diesel engines with minimal changes. In this chapter, vegetable oils blended with alcohols and diesel are analysed with respect to their properties for use in diesel engines, and the properties of biodiesel, alcohols, and pure diesel are also analysed. Biofuels are appropriate for diesel engines because of their physicochemical similarities to pure diesel. Alcohol and biodiesels have higher oxygen contents, which ensure complete combustion and less harmful emissions from engines. A decreased calorific value has a negative impact on engine efficiency. In the past, several volumetric blends of biodiesel and diesel were employed in diesel engines, but numerous studies have demonstrated that the B20 blend (20% biodiesel–80% diesel) provides the best performance and low emissions. Future fuels with ternary compositions of alcohol, biodiesel, and diesel have enormous potential. It is important to evaluate recent studies on the use of alcohols as fuel additives in the form of ternary blends. Therefore, this chapter is centred on how ternary blends affect a diesel engine’s ability to perform better, with low emissions. It was found that adding between 10 and 80% of biodiesel and between 5 and 45% of alcohol to diesel was the most appropriate solution.
