“…This parameter increases as a result of fuel oxidation. Acidic conditions exceeding the standard ASTM 6751 specifications provoke further swelling and degradation in elastomers, and corrosion issues in metallic materials [7]. In this case, the B100, B80, and B50 are out of spec fuels.…”

Nowadays, biodiesel is being promoted worldwide as a sustainable and alternative to diesel fuel. However, there is still a lack of a biodiesel market in Mexico. Hence, a new initiative to reform the Mexican biofuels framework by decree includes the production and use of biodiesel. This regulation can ensure and contribute to the development of the biodiesel market in Mexico. The initiative proposes to start from the B5.8 blend by the end of 2017 and reach the B10 by 2020. Therefore, the objective of the present work was the quality assessment of biodiesel blends proposed by the new Mexican policy framework. The techniques applied were Fourier transform infrared (FT-IR) spectroscopy, X-ray fluorescence analysis, scanning electron microscopy analysis, viscosity, higher heating value, thermogravimetric analysis, refractive index, acid number, specific gravity, flash point, and copper strip corrosion based on ASTM standards. The results indicate that the biodiesel and its blends B5.8 and B10 fulfilled relevant quality specifications established in the ASTM D6751 and EN14214 standards for fuels. However, the fuel blends presented a higher heating value (HHV) diminution. The experimental HHV percentages decrease for the mandatory mixtures compared to diesel were 2.29% (B10), and 0.29% (B5.8).

“…Besides the use of WVO, biodiesel from castor oil and inedible oilseeds from Mexicali Valley has been obtained. Subsequently, there have been developed research projects on topics related to the inventory of residual feedstocks to produce biodiesel, the performance of internal combustion engines operating with diesel-biodiesel blends, as well as the study of the behavior of materials exposed to diesel, biodiesel and mixtures of both [6,15,16,[19][20][21]. Research focused on the production of biodiesel via enzymatic has been conducted as well [22][23][24][25].…”

“…The leading standard setting organization ASTM International, formerly ASTM (American Society of Testing and Materials) defines biodiesel as a fuel comprised of mono-alkyl esters of long chain fatty acids [5]. Biodiesel is produced by transesterification of vegetable oils or animal fat, with a short chain alcohol in the presence of a catalyst, according to the following reaction shown in Figure 3 [6].…”

“…According to International Energy Agency (IEA) currently 120 operating solar-thermal systems for process heat are reported worldwide, with a total capacity of about 88 MW (125,000 m 2 ) [6]. Recently, biodiesel has become more attractive because of its environmental benefits and by the fact that it is produced from biomass, a renewable resource [10,11]. However, the production cost of biodiesel is the main obstacle for the marketing of the product [12,13].…”

Recent research and development of clean energy have become essential due to the global climate change problem, which is caused largely by fossil fuels burning. Therefore, biodiesel, a renewable and ecofriendly biofuel with less environmental impact than diesel, continues expanding worldwide. The process for biodiesel production involves a significant energy demand, specifically in the methanol recovery stage through a flash separator and a distillation column. Traditionally, the energy required for this process is supplied by fossil fuels. It represents an opportunity for the application of renewable energy. Hence, the current study presents a system of thermal energy storage modeled in TRNSYS5 and supported by simulations performed in ASPEN PLUS5. The aim of this research was to supply solar energy for a methanol recovery stage in a biodiesel production process. The results highlighted that it is feasible to meet 91% of the energy demand with an array of 9 parabolic trough collectors. The array obtained from the simulation was 3 in series and 3 in parallel, with a total area of 118.8 m 2 . It represents an energy saving of 70 MWh per year.
