Abstract

Different non-food-grade oils characterized by a high content of free fatty acids have been successfully deacidified with the use of commercial resins Amberlyst®46 (A46), Purolite®D5081and zirconium sulphate. Not refined or waste oils have been selected in order to reduce the biodiesel production costs, mostly depending on the raw material’s high price. Five sulphated, Zr-based, catalysts have been synthesized through different methods based on sol-gel or impregnation techniques and tested in the same reaction. The role played by the different catalysts’ features in affecting their catalytic activity in the studied reaction is discussed. The economic sustainability of the whole process is also assessed.
