“…Furthermore, previous studies focused on jatropha or castor seed oil methyl ester blends with commodity FAMEs such as SME, PME or canola oil-based biodiesel [17,19e23,25]. Lastly, a review on the topic of predicting properties of biodiesel blends using mathematical models was focused on cold flow, cetane number, energy content, density, flash point, viscosity, and vapor pressure [38]. The current study differentiates itself from prior art by expanding both the fuel properties investigated of the blends as well as providing insights on hitherto unreported biodiesel blends prepared from alternative feedstocks.…”

a b s t r a c tFatty acid methyl esters (biodiesel) prepared from field pennycress and meadowfoam seed oils were blended with methyl esters from camelina, cottonseed, palm, and soybean oils in an effort to ameliorate technical deficiencies inherent to these biodiesel fuels. For instance, camelina, cottonseed, and soybean oil-derived biodiesels exhibited poor oxidative stabilities but satisfactory kinematic viscosities. Field pennycress and meadowfoam seed oil methyl esters yielded excellent cold flow properties but high kinematic viscosities. Thus, field pennycress and meadowfoam-derived biodiesel fuels were blended with the other biodiesels to simultaneously ameliorate cold flow, oxidative stability, and viscosity deficiencies inherent to the individual fuels. Highly linear correlations were noted between blend ratio and cold flow as well as viscosity after least squares statistical regression whereas a non-linear relationship was observed for oxidative stability. Equations generated from statistical regression were highly accurate at predicting KV, reasonably accurate for prediction of cold flow properties, and less accurate at predicting oxidative stability. In summary, complementary blending enhanced fuel properties such as cold flow, kinematic viscosity, and oxidative stability of biodiesel.Published by Elsevier Ltd.

“…The cloud point of the blends in this work was determined according to the ASTM D2500 method. Pour point is the temperature at which a fuel loses its ability to flow and the wax becomes semisolid, like a gel losing its flow potential [16][17][18][19]. The pour point of the blends in this work was determined according to the ASTM D97 method.…”

Biodiesel is a renewable and reduced-emission alternative fuel produced mainly from the alcoholysis of vegetable oils and/or animal fats. It is mainly used in blends with diesel fuel to reduce emissions, enhance lubrication and lower sulfur content. Being able to accurately determine the physicochemical properties of blended fuel is important for optimal injection, combustion, and lubricating performance in diesel engines. Also, fuel properties vary as the ratio of biodiesel-diesel changes, affecting the final fuel quality. In this study, a wide range and narrow intervals of (0,2,4,6,8,10,12,15,18,20, 25, 35, 50, 75 and 100% by volume) off-quality canola-based biodiesel blends were prepared at ambient conditions and used to study the blended fuel properties (density, kinematic viscosity, flash point, cloud point and pour point). This is particularly important for examining the effect of a biodiesel content of more than 20%-the industry maximum blend content-on cold flow properties, fuel stability, energy value, and emissions. It was found that the kinematic viscosity and density increased linearly as the concentration of the biodiesel in the blend increases. The pour point and cloud point temperature showed a small increase up to 35% blending ratio and a rapid increase in temperature for biodiesel concentrations higher than 35%. Also, the flash point remained almost constant at an average value of 73 • C for blends less than 20%, above which the values for the flash point increased exponentially with biodiesel concentration. Furthermore, predictive correlations were developed for all tested fuel properties from regressing corresponding experimental data. All models exhibited excellent agreement with experimental data with an average absolute deviation of less than 5%.
