Evaluation of peanut oil as a “drop in” fuel source to expand market opportunities for U.S. peanuts and sustain rural economic development. These “drop in” fuels include jet (JP-5) and/or diesel (F-76 marine) fuel in support of the U.S. Navy’s biofuel mandate as well as Jet A and Jet A-1 for commercial jet fuel. In addition, the use of peanut oil as a green hydraulic fluid for both industrial and food grade usages will be explored.
Research on peanut oil for the purpose of converting triglyceride-type oils or fatty acids into the precursors for renewable jet and diesel fuel for certification by ASTM and the U.S. Navy. The specific fuels of interest are JP-5 jet fuel and F-76 marine diesel that are consumed by the U.S. Navy. A unique characteristic of these fuels is their 60°C flash point, which improves the safety of shipboard operations. Commercial jet fuels (Jet A and Jet A-1) have a flash point of 38°C and commercial diesel #2 has a flash point of 52°C. The scope of their testing will include processing of peanut oil into naphtha, jet, and diesel fuels. The approach includes: 1. Hydrothermal Cleanup (HCU) and Glycerin Recovery. 2. Conversion Peanut FFAs (Free Fatty Acids) to Renewable Crude Oil. 3. Hydrotreating of Renewable CH Crude Oil. 4. Fractionation of the Hydrotreated Product. 5. Analysis of Jet and Diesel Fuel Samples. The end result is trial blends to determine the suitability of peanut oil for production of jet and diesel fuels and also to determine the fractions that result in the maximum yield of each that still meets flash point, freezing point, and cloud/pour point requirements.
