Low Temperature De-acidification Process of Animal Fat as a Pre-Step to Biodiesel Production

Catalysis Letters Aims and scope Submit manuscript

Abstract

An esterification process is proposed to lower Free Fatty Acids (FFA) content in waste animal fat using solid acid ion exchange resins as catalysts. The final aim is to make this material a suitable feedstock for biodiesel production. Its exploitation does not interfere with the food chain, besides allowing to lower biodiesel production costs.
