- The synthesis of biodiesel fuel from vegetable oil in supercritical methanol was
investigated. The sensitivity of various parameters on the reaction was studied from a series
of batch and continuous experiments. The composition of products was measured by gas
chromatography and titration method. In supercritical methanol, high conversion can be
obtained in a short time compared with conventional process, however, the loss of fatty acid
methyl ester can be occurred due to thermal decomposition and oligomerization of reactants
and products. The application of heterogeneous catalyst was examined to prevent the loss by
lowering reaction temperature and decrease the use of methanol.
