Description
The use of renewable energy carriers in the mobility sector can happen by replacing fossil fuels. One option is biodiesel, which is obtained from vegetable oils. It is produced by adding methanol and potassium hydroxide (as 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 experimental plant.
The chemical reaction takes place at temperatures of around 60°C. The products leave the reactor after a predefined dwell time. The products are a two-phase mixture: A biodiesel-rich phase and a phase with by-products. The by-products are pumped out of the following phase separator. The options for the biodiesel-rich phase are: Return to the reactor, second transesterification stage, methanol recovery (distillation) and biodiesel washing (absorption).
