BIODIESEL PRODUCTION PROCESS FROM ACID OILS, FREE FATTY ACID ADSORBENTS, PRODUCTION AND USE PROCESS

摘要

"Biodiesel Production Process from Acid Oils, Reactive Free Fatty Acid Adsorbers, Production Process and Use" The present invention relates to a biodiesel production process from acid oils comprising a reactive acid adsorption step free fatty acids and a transesterification step. Such a process may be carried out without any prior oil washing or purification step. The reactive adsorbents of the present invention are obtained by a process which allows the synthesis of calcium, magnesium, strontium or barium oxide or hydroxide nanoparticles supported on mesoporous materials (silica mcm-41 or activated carbons) capable of efficiently removing fatty acids. free in vegetable oils.
