Thermal stability of diesel fuels by quantitative gravimetric JFTOT
- Naval Research Lab., Washington, DC (United States)
The gravimetric jet fuel total oxidation tester (JFTOT) was developed several years ago to provide JFTOT conditions which measure quantitatively the solid/deposit products formed in aviation fuels. The gravimetric JFTOT has now been used to measure these products in a small set of typical diesel fuels. These baseline data are compared to a much larger data base of jet fuels and also several pure compounds. Results from the diesels indicate that the gravimetric JFTOT is a useful concept for ranking fuels for their thermal stability. The diesels ranged from quite low (better than jet) to quite high (an order of magnitude greater than jet fuel) in their deposit forming tendencies. Properly ranked fuels can be used in device tests such as diesel injectors and gas turbine nozzles to assess deposition. In addition, diesels with appropriate viscosities may be able to be used as aviation fuels provided the gravimetric JFTOT gives a low deposition rating.
