“…A little over a decade ago, several researchers concluded that the difficulty in managing the glycerol produced during biodiesel synthesis constitutes enough technical and economic problems to be considered as a viable option to replace fossil diesel, at the pace foreseen by the current international agreements. In this context, the production of biofuels, in the same process of obtaining FAMEs, that generate glycerol derivatives instead of glycerol itself, seemed the best option to avoid the huge amounts of glycerol produced in the conventional transesterification process and also avoid the process of separation and cleaning of residual glycerol dissolved from the FAMEs mixture which constitutes the raw biodiesel [28,30,[49][50][51][52]. In this respect, among the alternatives described for the integration of glycerol as a biofuel, it is necessary to highlight those that prevent the generation of glycerol in the same biodiesel production process, that is, processes in which together with the corresponding FAMEs mixture, some derivatives of glycerol, such as glycerol triacetate (or Glyperol), glycerol carbonate (or DMC-Biod), or monoglyceride (like Ecodiesel) are also obtained.…”

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.

“…Biodiesel is a safe, renewable, non-toxic, biodegradable and much less polluting fuel for the environment than conventional diesel (Chakraborty et al, 2015;Gomez-Castro et al, 2015;Khang et al, 2018;López-Díaz et al, 2018). Therefore, even though the cost of biodiesel is greater than the diesel oil, many governments support the development of this biofuel considering mainly environmental aspects (Elms and El-Halwagi, 2010).…”

In this paper was assessed the potential of biodiesel production from Jatropha curcas oil. The proposed process was simulated in the software Aspen Plus™ involving the stages of trans-esterification reaction, methanol recovering, purification of the obtained methyl esters, catalyst removing, purifying of glycerol and the energy integration through heat exchange networks (HEN). The biodiesel process was carried out through the catalytic reaction of transesterification of Jatropha oil with methanol using a molar ratio of methanol oil of 6:1, and with 1% w/w of NaOH (related to oil mass) as catalyst. Under these conditions, it is technologically feasible to carry out the production of biodiesel. With energy integration through the synthesis of HENs, reductions of 100% and 41.3% of hot and cold utilities were achieved. This way, the utility cost decreases 70.92%. The net present value (NPV) for the integrated process was 70.64% higher than the one corresponding to the non-integrated process under the same production conditions.
