Abstract: 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.

Abstract: The present disclosure belongs to the technical field of clean and efficient mining of deep unconventional or conventional resources, and discloses a pilot-scale supercritical water oxidation oil and hydrogen production system capable of realizing multi-stage heating of organic rock. The system comprises a supercritical water generator, a supercritical water pyrolysis reaction system for organic rock, an oxygen injection system and an oil-gas condensation and collection system, wherein the supercritical water generator mainly comprises a water injection system, a front-section preheating system, a second-stage heating system and a third-stage heating system. The reaction system can carry out a pilot-scale simulation process of supercritical water pyrolysis for organic rock, a multi-stage heating function is realized, the maximum reaction distance is 8 m or more, and the release characteristics of oil-gas products under different reaction distances are explained.
