Abstract:
1. A continuous non-catalytic 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.
