Abstract

Purification of Jatropha Methyl Ester extracted from neutralized oil through dry washing using ion exchange resin Amberlite as adsorbent. The effect of amount of Methanol in excess, contact time, resin-to-biodiesel ratio and mixing speed was tested and analyzed for optimization of the purity of biodiesel. Optimum conditions were set to maximize the purity as well as minimize the four parameters. The components of the samples were analyzed using Thin Layer Chromatography (TLC) and QuantiScan Version 3.0. Of the four parameters, amount of excess Methanol has the greatest significant effect on the purity of biodiesel, while contact time has the least. Generation of design matrix, fitting of a model was done using Design Expert® 8.0.1. It was observed that to maximize the purity of the biodiesel, the set conditions are 1% methanol in excess, 30 minutes of contact time, 200 rpm of rotation speed and 1.75 resin-to- biodiesel ratio. The purity of the biodiesel at those conditions was verified at 98.80% through a confirmatory test.
