Reactors for Biodiesel Production – Farm Energy

The main characteristic of a batch reactor is that it starts with unreacted material, causes it to react, and then at a later time ends up with reacted material. That is, a batch reactor contains different types of material depending on which time one happens to look at it. Batch reactors are generally used in small biodiesel production plants.
