“…The economic factors affecting biodiesel production could be the cost of raw material, capital and chemicals used and capacity of plant and technology used. Out of these, 80% is the raw material cost and the rest includes cost of chemicals (catalyst and methanol) as well as labour (Panda et al 2018). In this work, the estimated cost of production (US$) of KME from neat karanja oil was found to be 0.7/lit that is inclusive of raw material cost, cost of chemicals and labour expenses.…”

The present work studies the influence of di-tertiary-butyl peroxide (DTBP) as a cetane-improving additive to karanja methyl ester (KME) on the combustion, performance and emission characteristics of a diesel engine. KME produced by base catalyzed transesterification of non-edible karanja oil was blended with DTBP in different volume proportions to result KMED1 (99% KME + 1% DTBP), KMED2 (98% KME + 2% DTBP), KMED3 (97% KME + 3% DTBP) and KMED5 (95% KME + 5% DTBP) fuel blends. With increase in DTBP content, viscosity was reduced, whereas the cold flow properties, cetane index and calorific value were enhanced. Engine test results exhibited improvement in brake thermal efficiency and brake specific energy consumption for all blends compared to neat KME. Combustion analysis showed improved combustion with rise in DTBP content in the blends. The CO, HC and NOx emissions with KME-DTBP blends were less compared to neat KME and the same significantly reduced with rise in DTBP percentage in the blends. This shows improved combustion due to more oxygen availability and improvement in fuel properties with addition of DTBP to KME. However, the NOx emissions were marginally higher with KME-DTBP blends compared to neat KME and diesel that may be further studied.

“…The oils used in this study were neat diesel, Madhuca Indica Methyl Ester (MIME) of 99.9% purity [13]. 2-Ethylhexyl nitrate (2-EHN) is usually used with a blend of diesel to rise its cetane number [14,15]. Triacetin is a 56 highly oxygenated additive to fuel which can be used in the combustion process.…”

“…So, previously, other theories like desirability function approach, grey relation theory and utility theory [24][25][26] were combined with the Taguchi method. Practically, assigning individual responses priority weights are based on assumptions and it won't lead to an optimum solution and may lead to uncertainty [15]. To solve this problem the fuzzy-based Taguchi method is adopted.…”

The continuous dependency on fossil fuels for energy requirements, transportation and power generation sectors the research has increased considerably on alternative source of fuel. Recently, it can be seen that Madhuca Indica Methyl Ester is gaining popularity due to its economical nature, the similarity with diesel’s properties. The primary aim of this research is to implement blends of Machuca Indica biodiesel using two different additives, 2-EHN and triacetin in different ratios for investigating single cylinder direct injection diesel engine output. In the current analysis, a Taguchi optimisation technique based on fuzzy logic is used to find the optimal combination of emission and performance parameters in order to make prediction of optimal input blends. It shows that the cylinder pressure of the blends is always higher than diesel. Among all blends, BL2 possesses the highest cylinder pressure under various load conditions. In terms of brake thermal efficiency, Among the blends, BL2 and BL3 possess BTE 12%, and 11% more than plain diesel in full load respectively. At maximum load, BSFC of Blend 2, 3 and 6 are (25, 22.5, 20)% less than plain diesel. BL5, BL6 and BL7 produced 3%, 1% and 0.3% less NOx than diesel. It is seen that BL2, BL3 and BL5 had lowermost UHC emission of 34%, 27% and 26% than pure diesel at maximum load. This multi-objective optimization technique shows that the blend BL6 have optimal MPCI value of 0.75.

“…Regarding the investigations carried out on the blends triacetin/biodiesel and triacetin/diesel, the combination of 10% by weight of triacetin with biodiesel is the one that shows the best results [155][156][157][158][159][160][161][162][163][164][165][166][167][168][169][170]. Finally, beneficial effects of triacetin on the cloud point and cold filter plugging point have also been revealed in several studies [171][172][173]. About the economic viability of the process of interesterification of triglycerides with methyl or ethyl esters Authors studied several reaction conditions, i.e., oil/methyl acetate molar ratio in the range 1:3 to 1:9, and temperatures in the range of 40-200 • C. This biofuel exhibited similar properties as biodiesel, although the obtention process of Gliperol improves the yield, the efficiency, and the economic feasibility of the conventional biodiesel obtention process.…”

The delay in the energy transition, focused in the replacement of fossil diesel with biodiesel, is mainly caused by the need of reducing the costs associated to the transesterification reaction of vegetable oils with methanol. This reaction, on an industrial scale, presents several problems associated with the glycerol generated during the process. The costs to eliminate this glycerol have to be added to the implicit cost of using seed oil as raw material. Recently, several alternative methods to convert vegetable oils into high quality diesel fuels, which avoid the glycerol generation, are being under development, such as Gliperol, DMC-Biod, or Ecodiesel. Besides, there are renewable diesel fuels known as “green diesel”, obtained by several catalytic processes (cracking or pyrolysis, hydrodeoxygenation and hydrotreating) of vegetable oils and which exhibit a lot of similarities with fossil fuels. Likewise, it has also been addressed as a novel strategy, the use of straight vegetable oils in blends with various plant-based sources such as alcohols, vegetable oils, and several organic compounds that are renewable and biodegradable. These plant-based sources are capable of achieving the effective reduction of the viscosity of the blends, allowing their use in combustion ignition engines. The aim of this review is to evaluate the real possibilities that conventional biodiesel has in order to success as the main biofuel for the energy transition, as well as the use of alternative biofuels that can take part in the energy transition in a successful way.
