Abstract: A method is disclosed for obtaining an alkyl ester fuel, i.e., a biodiesel, and alcohol from a feedstock mixture of free fatty acids and/or glycerides mixed with a simple alcohol, such as methanol. The method uses an electrostatic probe to provide an electrical field within the reactor. This causes the glycerin molecules to precipitate out of the feedstock mixture. A drain is provided in the reactor, to drain the glycerin from the reactor. When the precipitated glycerin reaches a level to make contact with the electrostatic probe, an electrical circuit is closed, which causes the drain to open. When the level drops, the drain closes. Glycerin absorbs water and draining glycerin from the reactor naturally dehydrates the fuel.

Abstract: Compositions containing unsaturated fatty esters may be stabilized against atmospheric oxidation by the addition of an antioxidant package containing at least one nitroxide free-radical scavenger and at least one alkylalkanolamine. Compositions treated in this manner show good resistance to atmospheric oxidation and resultant viscosity increase. An advantage of the nitroxide free-radical scavenger is that it stops the oxidation of the unsaturated fatty esters already during the initiation stage. Moreover, it is much less volatile than for example the known alkylhydroxylamine oxygen scavengers. By the use of a nitroxide free-radical scavenger, the composition can thus be stabilized for a longer period of time. The stability period is moreover less affected by the supply of oxygen to the composition. The solubility problem of the nitroxide in the fatty ester component can be solved by dissolving the nitroxide first in the alkylalkanolamine.
