“…And the crystallization depends on the molecular packaging, and the interaction between the molecules, therefore, factors such as molecular weight, ramifications, and the presence of polar groups in carbon chains, have effects on these properties (Knothe & Dunn, 2009;Rodrigues et al, 2006). Santos, Souza, and Silva (2008) points out that babassu biodiesel has a freezing point of -3°C, in the study by (Silva et al, 2011) babassu biodiesel through transesterification by ethyl route obtained the freezing point around -8°C. Thus, despite having viability in tropical conditions, its freezing properties make its use as aviation fuel unfeasible, so it is necessary to bring innovative ways to improve this condition.…”

Through a review of the bibliographic base was identified the potential and difficulties of using biofuels based on babassu culture for use as aviation biofuel. Babassu palm is one of the most important crops for family farming in the north and northeast of Brazil due to its vast use potential. From babassu oil, by transesterification, good quality biodiesel can be obtained. However, it does not have the properties necessary to be used as aviation biofuel. Researches with biofuels from this culture and cultures with a similar organic profile were analyzed pointing out the feasibility of these biofuels as a mixture in aviation kerosene, nevertheless, these biofuels present several problems when used alone. Among the physical-chemical properties analyzed, the freezing point was a critical factor for not using these biofuels. This review points out the best results to improve the physicochemical properties of babassu biofuels to use as aviation fuel and present an important social factor to this palm uses.

“…The heating and cooling curves from the DSC analysis are represented in Figure 6. It is important to note from Table 1 that the majority of the esters of biodiesel are unsaturated (ethyl oleate), which gives a lower melting temperature compared with other biodiesels rich in saturated fatty acids such as babassu and palm kern oils (Silva et al, 2011;Knothe and Dunn, 2009), which are rich in saturated esters such as ethyl laurate, palmitate and stearate. However, when compared with biodiesel with high unsaturated esters (soybean and corn biodiesel), the melting temperature of microalgae ethylic biodiesel was lower.…”

Microalgae oil of the species Chlorella protothecoides was obtained via a donation of the Soley Biotechnology Institute (SOLEYBIO) and characterized according to the fatty acid profile. Ethylic biodiesel was prepared using methods adapted by the research group. Analysis of acidity, water content, and density and viscosity temperature dependence (293.15 K to 368.15 K) were performed for the oil and ethylic biodiesel. The biofuel was characterized in terms of its flash and cloud points, heat capacity and cetane number. The properties studied were compared with conventional vegetable oils and biodiesel, presenting little differences and demonstrating the high viability of biodiesel from microalgae oil.

“…Saturated esters increased kinematic viscosity, cloud point and pour point, since once their melting points are higher than unsaturated ones and increased with the increase in carbon chain, leading to crystallization of these compounds in low temperatures [21,22].…”

In Brazil the soybean oil is most utilized for biodiesel production due to its high production. Nevertheless, this feedstock presents low oxidative stability. This work aimed to evaluate the application of castor oil, babassu oil and beef tallow in soybean oil as an additive (\5 %) to improve thermal and oxidative stability of ethyl soybean biodiesel. The characterizations realized were gas chromatography, kinematic viscosity, thermal analysis and Rancimat. In the binary and ternary formulations were added 2-4 % (w/w) babassu oil, castor oil or beef tallow in soybean oil for promoting ethyl transesterification. Content of ester agrees with Brazilian biodiesel specification, except to soybean biodiesel with 2 % beef tallow (87.2 %). The increase in content of beef tallow in soybean oil for biodiesel synthesis led to an increase in the cloud point and pour point, mainly soybean biodiesel with addition of 4 % beef tallow. In relation to the kinematic viscosity all biodiesel formulations were in agreement with the Technical Regulation established by ANP 3/2014, except for soybean biodiesel with addition of 4 % beef tallow. Thermogravimetric curves indicated that 4 % ternary formulation was the most stable (245°C). In relation to oxidative stability, the most stable were soybean biodiesel with 2 and 4 % beef tallow and 4 % ternary formulation. Considering thermal, oxidative and flow properties, it is suggested that 4 % ternary formulation (soybean oil additive with 2 % babassu oil and 2 % castor oil) is the most appropriate for production of biodiesel.
