Lubricity and Derived Cetane Number Measurements of Jet Fuels, Alternative Fuels and Fuel Blends

摘要

The objectives are to perform bench top lubricity tests and measure cetane ratings on a given set of fuels and fuel blends per ASTM standards. Overall results indicate that the dilution of the synthetic fuel, by 50%, with petroleum fuel, results in the improvement of lubricity of the synthetic fuel to the level of petroleum fuel. Cetane ratings were measured by Cetane Index, Cetane Number and Derived Cetane Number (DCN). It was concluded that in general, blends with a higher ratio of a component with a high cetane rating will have an overall higher cetane rating and that blends with a higher ratio of a component with low cetane rating will have an overall lower cetane rating. It was concluded that the DCN results from two different sources have approximately 95% correlation.
