“…Figure 2a shows the diffractogram of SrO/Fe 3 O 4 , and it can be seen four 4 crystalline phases: The strontium hydroxide, according to the literature is associated with the decomposition mechanism of the precursor (SrO), where the carbonate and water vapor present in the atmosphere react forming hydroxide and CO 2 12,14,16 . The strontium hydroxide, in accordance to our previous works, does not have catalytic activity in the transesterification reaction 12,14 .…”

“…The TG/DTGA curves (Figure 3a, 3b) showed three weight loss of similar and specific masses. The first event occurs between 100 and 140 °C and is related to the evaporation of water adsorbed on the surface of materials 12 , the second one range to 450-580 °C was associated to the decomposition of strontium hydroxide 17 .…”

“…All experiments were carried out in a 250 mL flask connected to a condenser. The methyl alcohol and catalyst were stirred for 30 minutes and then the oil preheated at 65 °C 12,13 has been added. At the end of the reaction the catalyst has been magnetically separated, the excess of methanol has been removed in a rotary evaporator at 80 °C, and the glycerol has been separated from the product in the separatory funnel.…”

This work described a new magnetic material enriched with strontium as catalyst to produce babassu biodiesel. The use of magnetic materials has attracted attention due to easy and fast separation from reaction medium. Moreover, they are ecologically correct, due to they generate less discards to the environment. Techniques of analysis and characterization were carried out to check the synthesis of magnetite and strontium ferrite, besides to verify the presence of hydroxide and carbonate in the structure of the strontium oxide. The best catalytic activities presented conversions of 78.6% and 89.7% when using the catalysts SrO/Fe 3 O 4 and SrO/SrFe 2 O 4 , respectively. Density studies of the alkali active sites were performed to elucidate the best activity for the catalyst composed with SrFe 2 O 4 .

Concern about environmental problems and climate change has led to increasing efforts toward a transition of the global energy matrix to renewable sources. In this sense, biodiesel is a renewable and alternative biofuel proposal and castor bean and jatropha are interesting non-edible raw materials for its production owing to their high fatty acid content. Transesterification is the most common process applied to industrial-scale biodiesel production owing to its attractive economic characteristics. This process can be catalyzed by chemical (homogeneous or heterogeneous) or biochemical (enzymatic) catalysts. The choice of raw material, as well as the production route of biodiesel, will significantly influence the process parameters. Considering the importance of biodiesel production in Brazil, the present work explores biodiesel production routes focusing on these non-edible raw materials (jatropha and castor bean) and compares them with the process using soy bean, as this is one of the most used worldwide raw materia. In addition, an extensive literature review was performed and the software Microsoft Power BI Desktop was used to model and analyze the selected works, grouping them according to the pattern of each route's influence on process parameters. In addition, the technical scores of each route were determined. The homogeneous chemical route presented better scores and the most interesting parameters for all raw materials; however, considering the technical and environmental advantages related to biochemical and G Baioni e Silva et al.
