title: Ultrasonically driven continuous process for vegetable oil transesterification.
abstract: A bench scale continuous process for the manufacture of biodiesel from neat vegetable oils under high power low frequency ultrasonic irradiation was investigated. The experimental studies explored variations in alcohol-oil stoichiometry and type of oil. Important parameters such as residence time and reaction volume were considered. The highest conversion was achieved when short residence time was employed. The transesterification under ultrasonic irradiation is mainly influenced by the residence time in the reactor and alcohol-oil molar ratio.
