Abstract

This study aimed to optimize the dry washing purification of Jatropha curcas L. biodiesel. Synthetic magnesium silicate was used to remove the impurities through adsorption. Optimization was done using Response Surface Methodology (RSM) based on Central Composite Design. The following factors were varied: reaction temperature, adsorbent loading reaction duration and mixing speed. First, the glycerol was removed by allowing it to settle. Then, the adsorbent was contacted with the biodiesel. The components of the samples were analyzed using Thin Layer Chromatography and Quantiscan software. Preliminary analysis of data indicated that the high temperature, amounts of adsorbent and mixing speed decreases the purity of the dry-washed biodiesel. On the other hand, increasing the contact time increases the purity. Design Expert software was used to generate an empirical model. It was also used to predict the optimum combination in purifying biodiesel:1% adsorbent loading at 42°C, 20 min reaction time and 200rpm mixing speed.
