Cetane numbers (C#) for the homologous series of straight-chain, saturated n-alcohols, C5−C12 and C14, were determined according to ASTM D 613. Measured C# ranged from 18.2–80.8 and increased linearly with carbon number (CN). Regression analyses developed equations that related various physical properties or molecular characteristics of these alcohols to calculated C#. The degree of relationship between measured and calculated C# was expressed as R2. The decreasing order of the precision with… 
Cetane Number Prediction of Biodiesel from the Composition of the Fatty Acid Methyl Esters
In the present work, the measured cetane numbers (CN) of pure fatty acid methyl esters (FAME), as well as the FAME compositions and the reported CN of 59 kinds of biodiesels collected from literature
A Comparative Assessment of Biodiesel Cetane Number Predictive Correlations Based on Fatty Acid Composition
Sixteen biodiesel cetane number (CN) predictive models developed since the early 1980s have been gathered and compared in order to assess their predictive capability, strengths and shortcomings. All
Precombustion of fatty acids and esters of biodiesel. A possible explanation for differing cetane numbers
Fatty acids of C18 chainlength as well as their methyl, ethyl, n-propyl, and n-butyl esters were injected into a constant-volume combustion apparatus suitable for collecting material from the fuel
Recommended Correlations for the Surface Tension of Aromatic, Polyfunctional, and Glyceride Esters
Surface tension values for 79 esters, including aromatics, polyfunctional, and glycerides, have been compiled from databases, books, and papers in the literature. The data have been carefully
Graphical method to select vegetable oils as potential feedstock for biodiesel production
Chemical compositions of 80 vegetable oils were collected from literature and the properties of the obtainable biodiesel (methyl esters) have been predicted by empirical relationships. The purpose
Comments on reporting cetane index as cetane number for biodiesel
Measurement of cetane number (CN) of a mixture of fatty acid methyl esters (FAME) [biodiesel] from a large number of lipid sources is expensive. This has resulted in cetane index (CI) estimated by a
Cetane number is an important parameter in evaluating the quality of biodiesel fuel. Its determination is usually arduous and expensive, and the results obtained are not always accurate due to
Relating the cetane number of biodiesel fuels to their fatty acid composition: A critical study
Abstract The cetane number is one of the most significant properties to specify the ignition quality of a fuel for use in a diesel engine. The cetane number of biodiesel fuels is considerably


Effect of molecular weights of fatty acid esters on cetane numbers as diesel fuels
Cetane numbers for various esters of the saturated fatty acids from C8 to C18 have been determined according to ASTM D-613. For the methyl esters the cetane numbers were found to increase in a
Heats of combustion of fatty esters and triglycerides
Gross heats of combustion (HG) have been measured for three classes of fatty esters and two classes of triglycerides (TGs). The esters included saturated methyl esters, Me 6:0–22:0; saturated ethyl
