“…However, residues can also be used for biofuel production. Lourenço et al (2021) used rice bran to produce biodiesel. According to the authors, the biodiesel obtained complied with the specifications of the American, European, and Brazilian standards for the iodine index (IO), acidity index, saponification index, and moisture.…”

Currently, concern about the burning of fossil fuels and the consequences for the planet has increased and become the agenda of discussions at global levels. In this sense, biofuels are an important alternative, and this article seeks to review the literature on the use of microalgae as raw material for the manufacture of biodiesel, the transesterification process as a conversion method, the technologies used to optimize this process, the characteristics of biodiesel that are required by Brazilian legislation, and the challenges for production. Brazil has a very large potential for the production of these biofuels but their production on a large scale still requires further studies so that it can be part of the country's energy matrix, including in the agro-industrial sector.

“…In a study, it was found that a volumetric blend of 20 % RBO and 80 % petrodiesel is the most economically effective to be used in the existing diesel engines [34]. Hence, RBO is a suitable candidate for sustainable biodiesel feedstock, since it is abundantly available and unsuitable to be consumed by human [35].…”

“…Biodiesel production and consumption have rapidly expanded in recent years because of its positive environmental effects [1,2]. The most common method for obtaining biodiesel is the methanolysis of highly refined oil in the presence of homogeneous alkaline catalysts such as NaOH, KOH, CH 3 ONa, and CH 3 OK [3,4]. These homogeneous-basic catalysts, on the other hand, cannot be recovered or regenerated after the reaction and should be neutralized with acid or removed with a substantial volume of hot water, raising overall biodiesel production costs and causing significant environmental damage.…”

For efficient biodiesel production, an acid-activated clay (AC) modified by calcium hydroxide and sodium hydroxide (CaNa/AC) was prepared as a catalyst. CaNa/AC and Na/AC were characterized by Hammett indicators, CO2-TPD, FT-IR, XRD, and N2 adsorption techniques. The influence of catalyst dose, reaction temperature, methanol/oil molar ratio, and reaction time on the transesterification of Jatropha oil was studied. Due to the introduction of calcium, CaNa/AC displayed a higher activity and stability, thereby achieving an oil conversion of 97% under the optimal reaction conditions and maintaining over 80% activity after five successive reuses. The reaction was accelerated as the temperature rose, and the apparent activation energy of CaNa/AC was 75.6 kJ·mol−1. The enhanced biodiesel production by CaNa/AC was ascribed to the increase in active sites and higher basic strength. This study presents a facile and practical method for producing biodiesel on large-scale operation.
