Method of Manufacturing Bio-Diesel and Reactor

摘要

A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750° F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.

主权项

1. A method of forming bio-diesel comprising:
emulsifying a mixture comprising alcohol and a source of fatty acids; pressurizing and heating said emulsion until said alcohol is super-critical; pumping said emulsion through a vessel under substantially non-laminar flow; maintaining said substantially non-laminar flow of said emulsion and said super-criticality of said alcohol in said emulsion for at least about 1.5 minutes.
