TLDR
In this paper, a novel acid catalyst was prepared via sulfonation of incompletely carbonized coconut shell using concentrated sulfuric acid, and the design of experiments were performed using four factor-three-level central composite design coupled with response surface methodology to evaluate the interaction between two factors to determine the optimum process conditions.About:

Homogeneous, heterogeneous and enzymatic catalysis for transesterification of high free fatty acid oil (waste cooking oil) to biodiesel: a review.
TL;DR: It was found that using heterogeneous acid catalyst and enzyme are the best option to produce biodiesel from oil with high FFA as compared to the current commercial homogeneous base-catalyzed process, which still suffers from serious mass transfer limitation problems and therefore is not favorable for industrial application.
