Chapter 5 Properistics Of Characteristic Fuel Properties Of Mahua Methyl Ester
PROPERTIES OF MAHUA METHYL ESTER AND THEIR BLENDS WITH DIESEL
5.1 INTRODUCTION In this work, characteristic fuel properties of mixture of Mahua methyl ester and their blends with diesel in the proportions of 10:90, 25:75, 50:50, 75:25 and 100:0 respectively were studied. The characteristics fuel properties of Mahua methyl ester blends were found to be those of diesel oil.
5.2 MATERIAL AND METHODS The Mahua oil methyl ester was prepared by using three stage transesterification processes because their FFA level is more than 1%. In the first step, esterification reaction was carried out by adding 15 ml methanol to 100 ml Mahua oil and 0.5ml H2SO4. This reaction period was carried at temperature range between 550c to 600 c with reaction …show more content…

Mahua oil has more specific gravity 0.920 which is reduced to 0.870 after transesterification. Specific gravity of B25 is very close to the diesel oil which is 1.032 times higher than diesel oil. B100 has s g of 0.894 which is 1.098 times more than that diesel oil. Figure 5.2 indicates that specific gravity increases with the increase in % of biodiesel blend.

5.4.3 Flash point Table 5.1 shows that the flash point of Mahua oil, diesel oil, biodiesel. Flash point of B10 is 700C. Flash point of B25 is 760C. Figure 5.3 shows the flash point increases with the increase in % of biodiesel in the blend. Figure 5.3 Flash points of Mahua oil, biodiesel, and its blends
5.4.4 Fire point Table 5.1 shows that the fire point of Mahua oil, diesel oil, biodiesel. Fire point of B10 is 770C. Fire point of B25 is 800C. Figure 5.3 shows the fire point increases with the increase in % of biodiesel in the blend.
