United States Patent Application |
20050120621 |
| Kind Code | A1 |
| Lawson, J. Alan ; et al. | June 9, 2005 |
Chemical synthesis method comprising electro-catalytic reaction and apparatus therefor
Methods, systems, and devices are provided for synthesizing one or more chemical products from a renewable oil, comprising the step of flowing a fluid which comprises a renewable oil through a high voltage electrical field effective to catalyze a chemical reaction involving the renewable oil. Examples of renewable oils include vegetable oils, animal fats, bio-oils, and combinations thereof. In one embodiment, the fluid further comprises an alcohol mixed with the oil, and the chemical reaction produces biodiesel and an etherified glycerin. In one embodiment, the biodiesel is further reacted to produce acetic acid.
