Production and Characterization of Biodiesel from Avocado Peel Oils using Experimental Analysis (ANOVA)

The crisis of energy due to the increasing awareness depletion fossil fuel resources, biodiesel is an alternative source and promising potential that grows rapidly, its high contribution environment friendly, renewable, non-toxicity, biodegradability, essentially sulfur-free, as a strategical renewable in substitution diesel oil contributes minimal amount net greenhouse gases. In this study, extracted used for production from waste avocado peel was investigated laboratory approach. Experimental results evaluate major optimum process parameters base-catalyzed transesterification on yield well properties. most important variables affecting methyl ester during reaction are molar ratio alcohol temperature. A 95.2% FAME conversion obtained using methanol/oil 6:1, 1.21g NaOH, time 67.5 min, 60 0C Important properties (characterization) produced are, (pHof 7.8, specific gravity 0.88, density at 15 0C, kg/m3, kinematic viscosity found be 4.22 m 2·s −1 40 flashpoint 161 Cetane number 49 well-matched relevant international standards quality produced. This result shows can compared those ASTM EN standards.
