Study on Preparation of Bio-diesel with Soybean Oil

Guo Deng

Abstract

A study was made of the reaction of transesterification of soybean oil by means of methanol,using NaOH as catalysts.The operation variables used were the molar ratio of methanol to oil,catalyst concentration,and temperature.The evolution of the process was followed by gas chromatography,determining the concentration of the methyl oleate at defferent reaction times.The results indicated that the optimal conditions for the transesterification of soybean oil are methanol to oil molar ratio at 6∶1,1.0% NaOH(w%)of oil and room temperature.The biodiesel has very similar properties to those of biodiesel DIN V 51.606 IN Austria and diesel 0 # in China
