Kinetics of the pre-treatment of used cooking oil using Novozyme 435 for biodiesel production

- An ultra performance liquid chromatography-mass spectrometry method has been developed.
- It was possible to separate and monitor the 1,2 and 1,3 diglyceride isomers.
- Mono- and diglycerides are more readily converted than triglycerides.
- A kinetic model to track the key components has been developed.
