Biodiesel
• Made from plant oils• No modification of engine• Lower emissions• Carbon neutral• Renewable energy source

Reactive Distillation
• The merging of a reactor and a distillation column in one
• Much interest in this technology• Can save a lot of money• Not always feasible

Summary
• The model shows the same trends as in the literature.
• The model is not ideal and some challenges still exists.
• The chemical equilibrium needs to be modelled a different way to get more accurate results.
