- •
Heterogeneous transesterification of triolein to produce biodiesel is studied.
- •
Experiments have been performed on a pilot unit including two fixed bed reactors.
- •
A pseudo-homogeneous model has been developed to determine kinetic parameters.
- •
A heterogeneous model has been used to estimate molecular diffusion.
