    摘要: The chemical conversion of renewable oil to obtain a hydrocarbon product suitable as a fuel, includes (i) renewable oil including corn distillers oil (CDO), fatty acid glyceryl esters (FAGE), triacylglycerols (TAG), lipids, and free fatty acids (FFA), which are derived from non-fossil-fuel sources that include animals, plants, vegetables, fruits, grains, algae, and plankton (collectively “oil”); (ii) the chemical transformation of the oil by substantially reducing or eliminating the carboxylate functionality and native unsaturations of fatty acids contained therein; (iii) wherein the hydrocarbon product is substantially a mixture of saturated hydrocarbons, or alkanes, originating from corresponding structures in the oil, e.g., the hydrocarbon chains of fatty acids; and (iv) the product mixture is suitable as fuel that may be blended with or be used in place of fuel such as diesel derived from petroleum.

    摘要: A system and method is provided for upgrading a continuously flowing process stream including heavy crude oil (HCO). A reactor receives the process stream in combination with water, at an inlet temperature within a range of about 60° C. to about 200° C. The reactor includes one or more process flow tubes having a combined length of about 30 times their aggregated transverse cross-sectional dimension, and progressively heats the process stream to an outlet temperature T(max)1 within a range of between about 260° C. to about 400° C. The reactor maintains the process stream at a pressure sufficient to ensure that it remains a single phase at T(max)1. A controller selectively adjusts the rate of flow of the process stream through the reactor to maintain a total residence time of greater than about 1 minute and less than about 25 minutes.
