Experiment Study on Biodiesel Produced from Soybean Oil by Solid Base Catalysts

In this paper, biodiesel is successfully produced by the ester exchange reaction with solid base catalyst of K2O/Ti-HMS based on soybean oil as raw materials. The result of which shows that K2O/Ti-HMS has good ester exchange activity as solid base catalyst and the catalyst easily is separated from products. By single factor experiment, the influence of K2O load, molar ratio of methanol and oil and catalyst dosage on the biodiesel conversion rate is researched and the optimal relationship between the above parameters is obtained.
