Study of Cetane Properties of ATJ Blends Based on World Survey of Jet Fuels
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 (50/50 ATJ/Jet 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 (50/50 ATJ/Jet 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.
