Production, Characterization and Performance Evaluation of Biodiesel from Avocado Seed Oil Using Autodesk Inventor Fusion

Abstract

The study examined the production, characterization and performance characterization of biodiesel prepared from avocado seeds. The Avacado SeedOil (ASO) was extracted from the seed through both mechanical and solvent extraction methods. 354 ml oil was extracted from1.2 kg seeds ofwindslowson cultivar, having 30% oil content. The extracted oil was characterized and converted to biodiesel using transesterification method with operational condition of methanol to oil molar ratio of 6:1, reaction time of 6 mins, and reaction temperature of 60 oC. TheAvacado biodiesel (ABD) produced was characterized to determine the fuel properties and evaluated on the basis of emission quality. The results of the oil properties indicate thatthe specific gravity,density, acid value, free fatty acid (%FFA), viscosityand higher heating valuewere0.9155, 915.5kgm−3 ,5.25 mg KOH/g, 0.104%,35.9 mm2 /s and 56.05MJ/kg respectively. The results of biodiesel characterized showed that thespecific gravity,density,viscosity,flash point,acid valueand heating valuewere0.869, 869 kgm−3 , 3.59461 mm2 /s, 80℃, 0.76 mgKOH/g and41.113MJ/kg respectively. It was noted that the emission quality wasCO, 0.75%; PM, 0.07%;, NOx 5.04𝑆 2.33%.for Carbon II Oxide, Particulate Matter, Oxide of Nitrogenand Sulphur contentrespectively.The ABD properties were compared with several limits prescribed in the ASTM D675-02 of biodiesel standards. It was concluded
