Process for the production of biodiesel in continuous mode without catalysts
First Claim
1. A continuous process of producing biodiesel, comprising:
- dispensing alcohol and vegetable oil;
pumping the alcohol and vegetable oil into a reactor;
applying a pressure between about 20 Bar and 400 Bar and a temperature between about 150°
C. and 450°
C. to the alcohol and vegetable oil in the reactor, thereby forming a mixture of non-reacted alcohol, glycerin, and esters;
releasing the mixture of non-reacted alcohol, glycerin, and esters from the reactor via a flow and pressure control valve;
cooling the mixture of non-reacted alcohol, glycerin, and esters in a cooler;
of the mixture of non-reacted alcohol, glycerin, and esters, separating an upper phase of non-reacted alcohol from an intermediate phase of esters and a lower phase of glycerin and directing the intermediate phase of esters and the lower phase of glycerin to a separation reservoir;
separating the esters from the glycerin.

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.
