Abstract
Embodiments herein relate to the production of alkyl esters from acidified soap stock. In an embodiment, a process for producing alkyl esters is provided. The process can include mixing acidified soap stock with an alcohol, water, carbon dioxide, and/or carbon monoxide, to form a reaction mixture, and contacting the reaction mixture with a catalyst under supercritical conditions for the alcohol, the catalyst including a metal oxide. Other embodiments are also included herein.
