  • Process for the production of biodiesel in continuous mode without catalysts
    Patent number: 7524982
    Abstract: A continuous, non catalytic process for producing biodiesel from vegetable oils and ethanol or methanol includes pumping a mixture of vegetable alcohol through a pump towards a tube shaped reactor, wherein the mixture is submitted to high pressure and temperature, where the resulting product is non reacted alcohol, glycerin and a mixture of esters (biodiesel) which is directed to the reservoir at the reactor outlet where an upper phase of alcohol is redirected through an alcohol return pipe to the pump inlet, and the intermediate phase, biodiesel, and the lower phase (mostly of glycerin) are led to the separation reservoir or decantation tank, where the alcohol is removed through the alcohol return pipe, being biodiesel and glycerin the final products, which are then collected for the end to which they were aimed.
