“…This is faster than 16 months duration used by Pedley et al [32] and lower cost than the system proposed by the ASTM D6186, and could be performed at the lower temperature than EN14112. GC‐MS enabled the tentative identification of numerous compounds, which could not be performed with the conventional IR approach [17] . GC‐MS was also able to tentatively detect aromatic compounds as that reported with the IR analysis [32] .…”

“…The properties of biodiesel are close to diesel fuel and are miscible with petrol‐diesel [9,10] . There is a report that biodiesel could fit in for petrol‐diesel in the engines without any modification on the engine [11] . Biodiesel production methods have also been improved until becoming an important component of an automotive diesel engine [12] .…”

“…The types of analyses include chromatographic, spectroscopic, physical properties‐based, and wet chemical methods [16] . For example, [17] performed the aging of biodiesel at 43 °C, 110 °C and 150 °C using infrared (IR) spectroscopy for the investigation. The aging led to formation of aldehydes, ketones, acids, alcohols, and heavier fractions which may not be effectively analyzed with the IR approach.…”

In this study, two‐phase electrocoagulation (EC) approach was developed and used to investigate blend of bio‐diesel and petro‐diesel (B10) stability under the electrochemical treatment. Gas chromatography‐mass spectrometry (GC‐MS) was used to analyze the aliquots before and after the reaction. The major compounds were alkanes and aromatic compounds with the minor contents of aldehydes, ketones, esters, alkenes, alkynes, halogens, oxygenated compounds, and heterocyclic compounds. The selected condition for the reaction was 10 V and 60 min which resulted in 9.9×109 counts per s total peak area of compounds containing from nine to seventeen carbon atoms (C9 to C17) compared with 6.8×108 counts per s for the control. The peak areas of the straight chain alkanes increased from 12 % to 33 % of the total peak areas observed after the experiment. Compounds with higher peak areas were found between C12 to C14 with the retention indices range of 1155–1678. The EC treatment mainly increased the straight and branched alkane and alcohol contents with the decreasing contents of branched cyclic alkanes. The developed system could be adapted to study the stability of other types of fuels. This is cost effective and can be performed within an hour at room temperature under atmospheric pressure.

“…TGA quantifies the physical or chemical transformation as a function of the temperature, , providing data that can be useful, for example, for the establishment of thermal stability . Such a technique has also been employed for biodiesel characterization as being a mixture of methyl or ethyl esters and has physical properties analogous to those obtained from pure esters. − …”

Use and Reusability of the Na/Nb₂O₅ Catalyst in the Ethanolysis of Different Feedstocks for Biofuel Production: Confirmation of Heterogeneity of the Catalyst

Niobium oxide impregnated with sodium (Na/Nb2O5) was used as a heterogeneous catalyst to produce biofuel from conventional raw materials, such as soybean oil and beef tallow, and non-conventional feedstocks, including andiroba, babassu, coconut, crambe, macaw palm, palm, palm kernel, and jatropha oils. The trials were performed at fixed conditions using 10% catalyst at 78.5 °C under stirring (600 rpm) for 5 h. On the basis of the results generated by gas and liquid chromatographies, high catalytic activity was found for all tested feedstocks, revealing yields higher than 95%. The purity of the ethyl esters was validated by thermogravimetric analysis and nuclear magnetic resonance. The Na/Nb2O5 catalyst performed efficiently, converting the fatty acids present in the lipid raw materials to the ethyl esters, and showed high stability in consecutive batches, generating products that meet the specificity of international standards. The heterogeneity of the catalyst was also confirmed by determining the sodium concentration in both biodiesel and the catalyst after consecutive batch runs.
