Effect of Variation of Temperature on the Transesterification of &lt;i&gt;Jatropha&lt;/i&gt; Seed Oil Using Homogeneous Catalyst

Since almond seed oil can be used for biodiesel production, this study is aimed at investigating the effect of different blend ratios on the fuel properties of almond biodiesel. The biodiesel was characterized for the properties of flash point, cloud point, pour point, viscosity, saponification value, peroxide value, acid value, iodine value, density and specific gravity using the Gas Chromatography Mass Spectrophotometer (GCMS). When blended with petrol diesel at ratios of 20%, 30% and 50%, results showed that the properties of the biodiesel obtained at a blend of 20% had properties more similar to the ASTM standard. At that proportion of 20%, the properties of acid value, viscosity, cloud point, pour point and iodine value were found to be 0.95meq/kg, 8.80Cp, 6 0 C, 1 0 C and 41.62gI2/100g respectively, except the flash point which was 72 0 C at biodiesel blend of 50%. This is because increase in blending ratios was found to result in corresponding increase of the properties.

“…To assess the quality of oil for biodiesel production, the fatty acid composition and free fatty acid content of the oil must be determined. Oils with high free fatty acids of over 3% must be esterified to reduce their free fatty acids before transesterification to biodiesel [74,76,77].…”

“…The fatty acid composition of the plant oil is an indication of its biodiesel quality and performance in compression ignition engines especially its cold flow properties [8,71,[74][75][76]. Plant oils whose structural fatty acid content has a sufficient number of double carbon bonds show promising biodiesel qualities such as good cetane number, good oxidative stability, lower viscosity with good engine atomization, and higher calorific value [1,71,72,74].…”

“…Among the plant oil biodiesel studied, Jatropha curcas biodiesel and algae biodiesel stands out in terms of quality and good fuel properties for use in compression ignition engines [36,47,48,56,71,74,75]. Some studies [5,25,56,[76][77][78] even report that Jatropha seed oil or its blend with conventional diesel fuel can be used as diesel in compression ignition engines without engine modification.…”

Due to population explosion, and increased industrialization with urban and rural development, the need for increased energy utilization has become more intense. Petrodiesel that has been the main energy source for heavy-duty automobiles or machines has contributed immensely to environmental pollution leading to climate change, an increase in illnesses, and reduced lifespan. To combat this ugly situation arising from the utilization of Petrodiesel, biodiesel is produced from plant oil or animal fats to substitute for Petrodiesel in internal combustion engines, either as neat biodiesel or as a blend with Petrodiesel. Different scientists and researchers have produced biodiesel from edible and non-edible plant oils. Their reports show that biodiesel properties depend on the nature of the parent plant oil and the production procedures taken. These properties that are due mainly to its production procedures determining their performance in internal combustion engines. In this chapter, recent findings on biodiesel properties with their effects on performance in internal combustion engines are reviewed. Researchers’ reports show that the most suitable blend of biodiesel with Petrodiesel is B20. This blend consisting of 20% biodiesel with 80% Petrodiesel has equivalent performance as Petrodiesel with fewer pollutants and only 1–7% nitrogen oxide emission.

This study aimed to examine the effects of transesterification reaction temperature on the biodiesel properties and diesel engine performance. Biodiesel properties evaluated in this work included viscosity, density, and methyl ester content. Meanwhile, the diesel engine performance testing comprised the examination of the engine’s torque and power. The research was conducted in several stages, viz. producing biodiesel from fresh cooking oil with variations in transesterification temperature of 45℃, 55℃, and 65℃; testing the characteristics of biodiesel produced; blending biodiesel with petroleum diesel to result in B30 biodiesel fuel; and testing biodiesel fuel (B30) in diesel-engined vehicles. It was revealed that the higher transesterification temperature led to the lower biodiesel viscosity, the decreasing value of biodiesel density values, and the higher methyl ester content. Furthermore, it was also demonstrated that increase of the transesterification temperature resulted in the higher value of torque and power generated. However, compared to the petroleum diesel fuel (B0), biodiesel fuel (B30) exhibited the lower values of the engine’s torque and power. The highest average values of torque and power of B30 fueled diesel-engine were 108.11 Nm and 43.51 kW, respectively, provided by the biodiesel produced at the transesterification reaction temperature of 65℃.of 65℃.
