Abstract:
The cetane properties of a fuel blend containing highly iso-paraffinic ATJ fuel and Jet fuel were studied. Literature review was conducted to obtain cetane properties from PQIS database, CRC report and Tri-Services report. Based on data collected from Task 2.4 of WD0024, on cetane properties of ATJ blends, correlation equations were developed to determine cetane properties as a function of volume percentage of ATJ in the fuel, which was used to determine cetane properties of maximum ATJ blends 5050 ATJJet fuel. The overall conclusion is that maximum ATJ blends from any jet fuel Jet A, Jet A-1, and JP-8 had an increase in CI from 7 to 8 using the four variable, D4737 method, while the increase in CI was approximately 3 using D976 method. Based on the extensive decrease in CN and DCN values much below 40, maximum ATJ blends 5050 ATJJet fuel blends were deemed not fit-for-use. It was concluded that the amount of ATJ that must be blended with Jet A or JP-8 to obtain 40 DCN, was less than 50 for all the PADD.
