Heterogeneous esterification of free fatty acid to biodiesel
The potential of sulphated zirconia (SZ) as heterogeneous acid catalyst for esterification of free fatty acid (FFA) to biodiesel has been investigated. Experiments using oleic acid as a model compound preceded the esterification of palm oil free fatty acid (POFFA) mixtures. The relation of reaction...

The potential of sulphated zirconia (SZ) as heterogeneous acid catalyst for esterification of free fatty acid (FFA) to biodiesel has been investigated.

Optimisation of esterification process via response surface methodology (RSM) for blended POFFA revealed maximum biodiesel yield (FAME) and conversion were 80.2% and 78.4%, respectively.
