“…Secondly, a complete conversion is hard to achieve since transesterification is a reversible reaction [26]. Thirdly, the high pour points of biodiesels from variable feed stocks, such as À12°C of biodiesel from corn oil [27], lower calorific value, cetane number, and oxidation stability are the intractable problems in the practical use of biodiesel [26].…”

a b s t r a c tThe transesterification of camelina sativa oil with methanol-1-butanol, and ethanol-1-butanol alcohol mixtures under supercritical conditions have been studied in order to maximize biodiesel yield and improve biodiesel quality. The influence of the variation of the molar ratio of methanol-1-butanol and ethanol-1-butanol from 1:0, 3:1, 2:1, 1:1, 1:2, to 0:1 on the yield of free fatty methyl esters/free fatty ethanol esters-free fatty acid butyl esters, the composition of the biodiesel blend mixtures, and the physical properties of the biodiesel have been investigated at the reaction temperature of 290°C, reaction time of 30 min, and the initial reaction pressure of 500 psi. A maximum yield of 86.14 wt% for free fatty acid methyl esters-free fatty acid butyl esters with the optimum cold property can be obtained at the molar ratio of methanol-1-butanol of 0.5-0.9. Also, a maximum yield of 85.60 wt% for free fatty ethyl esters-free fatty butyl esters with the lowest pour point can be achieved at the molar ratio of ethanol-1-butanol in the range of 0.5-0.7.

“…Several cold flow properties of the diesel and biodiesel fuel are generally used to classify cold weather performance, in terms of the cloud point (CP) and pour point (PP). Researchers have applied various experimental techniques to investigate the cold flow behavior of biodiesel (CP and PP) production from various feedstocks [28][29][30][31][32]. It was revealed that at the temperatures approaching the beginning of crystal formation, the viscosity rapidly increases, and the viscosity of the blend changes of between biodiesel and the diesel.…”

Biodiesel is an attractive alternative fuel for diesel engines produced from vegetable oils or animal fats by transesterification in the presence of a catalyst. The feedstocks used in this experiment for the production of biodiesel were waste frying oil (WFME) waste canola oil (WCME), and their different percentages are referred to as 25-WFME, 50-WFME and 75-WFME. The samples are sourced from Northern Cyprus. Also, biodiesel was produced at Mechanical Engineering research laboratory. The purpose of this study is to investigate the effect of the temperature on the kinematic, dynamic viscosity and density of the biodiesel samples. Also, this paper examines the cold flow properties as well as the kinematic viscosity, cloud point (CP) and pour point (PP) of the produced biodiesel. The density, kinematic viscosity, CP and PP measurements were made according to ASTM standards. The properties of the produced biodiesel such as viscosity and density were measured within temperature ranges 20-270°C in steps of 10°C. The kinematic viscosity, CP and PP were measured within temperature range -10-20°C. In this study, five general correlations were presented for estimating the density and kinematic viscosity of the blends at several temperatures. The experimental investigation showed that CP and PP of WCME increased with an increase in the concentration of WFME. Furthermore, empirical equations for predicting the viscosity, density, CP and PP for biodiesel samples give values in good agreement with experiments. The results obtained show that with the increase of the temperature, kinematic viscosity, dynamic viscosity and density decreased.

“…Acetone was found to be an effective stabilizer, which could also mitigate the increase in cloud point due to expanded polystyrene (EPS) addition. A study in [31] was performed to investigate the effect of parameters of the transesterification process on low temperature properties of corn oil biodiesel. It was found that catalysts and alcohol to oil ratios were both able to improve cold flow properties.…”
