“…The absence of arachidic and behenic acids in mixed biodiesel reduced combustion duration and interval compared to pure biodiesel. These obtained results are in line with those of Chabane et al 48 and Nicolas et al 49 Figure 7 shows a comparison of DSC combustion curves. Table 2 gives the reaction region temperature, peak combustion temperature, heat flow, and enthalpy.…”

Thermal characteristics of biodiesels are useful in system design, modeling, and operation. Such investigations are extensively being carried out in combustors, engine, and process industries. This article examines the thermal characteristics of jatropha (Jatropha curcas), honge (Pongamia pinnata), and their equal mixing from thermogravitometry and differential scanning calorimetry (TG‐DSC) curves for the specific 10°C/min heating rate under atmospheric air. Fuel properties are measured following ASTM standards to compare with diesel properties. Each experiment was repeated three times, and the properties showed insignificant scatter. The average properties of the repeated tests are presented. Two phases of decomposition were observed for diesel, whereas three (viz., devolatilization of aqueous fractions, combustion of methyl esters, and combustion of carbonaceous residues) in biodiesels. Jatropha oil methyl ester (JOME) is thermally stable compared to honge oil methyl ester (HOME). Mixed biodiesel (JOME+HOME) is prone to oxidation due to the high content of oleic and linoleic acids. Recorded onset and offset temperatures of mixed biodiesel are low compared to pure biodiesel. Mixed biodiesel exhibited high volatility resembling diesel characteristics. It exhibited an enthalpy of 240 J/g, whereas the enthalpy of diesel, jatropha, and honge exhibited enthalpies of 130, 321, and 570 J/g, respectively. The combustion index (S) of diesel, jatropha, honge, and mixed biodiesel was 41.6, 82.8, 77.74, and 64.6, respectively. Mixed biodiesel reduces the intensity of combustion (Hf), promising better combustion characteristics. Thus, mixed biodiesel shows the potential of an efficient alternative energy source.

“…The same structure found in the aforementioned work by Benziane et al [ 43 , 44 ] was followed vy Chabane et al [ 55 ], who reported the phase diagrams and Tammann plots of new binary mixtures involving two FAME and three alkanes (tetradecane, hexadecane and octadecane). The experimental results are also compared with the theoretical ones from different models.…”

“…Thus, other complementary techniques started being utilized, such as optical microcopy [ 41 , 56 ], X-ray diffraction (XRD) [ 36 ] and Fourier-Transform Infrared spectroscopy (FTIR) [ 48 ], allowing more precise and realistic phase diagrams to be developed. The improvement of the measuring devices also allows the management and reporting of additional data, which enables, for example, the representation of Tammann plots [ 26 , 32 , 34 , 35 , 42 , 43 , 47 , 49 , 50 , 52 , 54 , 55 , 56 ].…”

“…Predictive models are studied and evaluated for the measured mixtures by almost all the aforementioned authors, with the exception of older articles [ 27 , 28 , 29 , 38 , 39 , 40 ] and in the work of a few more recent authors evaluating the use of FAE as PCM [ 29 , 48 , 50 ]. Scientists researching on biodiesel are the ones who extensively report the comparison of experimental results with theoretical models, using mainly UNIQUAC [ 31 , 32 , 34 , 37 , 42 , 43 , 44 , 49 , 55 ], UNIFAC [ 30 , 31 , 52 , 53 , 55 , 58 , 59 ], Flory–Huggins (especially Robustillo’s team) [ 35 , 45 , 46 , 47 , 52 , 53 , 55 , 58 , 59 ] and ideal models, based on Schraeder’s equation [ 36 , 43 , 44 , 49 , 52 , 53 , 54 , 55 , 58 , 59 ]. The use of these models allows the description of the mixtures’ phase change behavior using only data from the pure materials, based on thermodynamic equations [ 35 , 45 , 46 , …”

Evolution of the Study of Phase Diagram of Binary and Ternary Mixtures Involving Fatty Acid Esters

et al. 2021

View full text Add to dashboard Cite

Interest in phase change materials keeps on rising as thermal energy storage grows in popularity in the scientific community as a promising complement for renewable energies in the future. Extending the possibilities beyond pure compounds, the use of mixtures (especially eutectics) widens the range of suitable phase change materials (PCM) available in the market. However, a precise knowledge of the mixtures’ phase behavior is required, making phase diagrams the most appropriate tools to follow. The aim of this work is to collect and analyze published literature concerning the phase diagrams of fatty acid esters mixtures, which constitute promising candidates as PCM due to their attractive properties, such as high latent heat, chemical stability and the possibility of extracting them from vegetable and animal oils. The topic appears as a still open scientific field, where further studies need to be performed to complete, complement and perfect the currently available information.
