Abstract
Biodiesel is a kind of clean and renewable energy which can be used directly or mixed with fossil diesel as fuel on vehicles. It can be extracted from recycled vegetable oil or animal fat by using blending, diluting, microemulsion, pyrolysis, or transesterification method.ransesterification means that appropriate amount of alcohols and fat are mixed in supercritical condition with various kind of catalyst to produce esters. It is a common process in producing biodiesel. By using all kinds of catalyst, heterogeneous catalyst is relatively environment-friendly and makes a simple process.n this study, soybean oil is mixed with methanol under 60℃ with hydrotalcite as catalyst to investigate the effect of Mg/Al molar ratio and calcination temperature to the conversion. s result, hydrotalcite made at 550℃ and Mg/Al ratio in 3 has the best conversion. Optimal condition of transesterification is at 60℃, 8hrs, Methanol/Oil=15, catalyst of 5%.
