Pretreatment of High Free Fatty Acid Feedstocks for Biodiesel
When working with feedstocks that contain 5% FFA or higher, it is important to convert the FFAs to biodiesel or the process yield will be low. There are at least four techniques: Enzymatic Methods, Glycerolysis, Acid Catalysis, and Acid Catalysis followed by alkali catalysis.
