The use of renewable energy carriers in the mobility sector can occur by replacing fossil fuels. One option is biodiesel, which is obtained from vegetable oils. It is produced by adding methanol and potassium hydroxide (as a catalyst) and is a transesterification, a chemical equilibrium reaction. On a large industrial scale, production is carried out continuously in stirred tank reactors. This process is demonstrated on a small scale by the CE 650 experimental plant. The chemical reaction takes place at temperatures of around 60°C. The products leave the reactor after a predefined residence time. The products are a mixture of two phases: A phase rich in biodiesel and a phase with byproducts. The byproducts are pumped out of the next phase separator.
