“…Likewise, relatively low sulfur levels are permitted in rocket kerosene in an attempt to minimize surface fouling due to corrosive copper-sulfur reactions leading to deposit buildup in copperbased regenerative cooling passages. 9 Vapor pressure requirements (not shown) and distillation temperature limits for JP-7 permit safe fuel system operation under high heat loads accompanying supersonic flight, while shipboard storage safety concerns impose a higher flash point for JP-5 than for its ground-stored counterpart, JP-8. 3 Note that compositional requirements exist largely through limitations on certain constituents (e.g., mercaptan sulfur), but fuel composition in terms of hydrocarbon classes such as straight chain (n-), branched (iso-), and cyclic paraffins is not specified.…”

“…The effect of sulphur compounds in the fuel leads to decreased efficiency, increased pressure drop in the system, and loss of structural integrity possibly result in engine failure. 32 Further SOx emissions from the products of combustion are harmful to the environment. A possible solution to this problem is to modify the specification of fuel by decreasing the total sulphur content allowed.…”

Kerosene based hydrocarbon fuels are preferred candidates for the source of energy due to its stable properties. Based on the requirement of the combustor and the growing concern over pollutant, kerosene based fuels are modified. The fuel under investigation is a modified form of kerosene with ultra-low sulphur content. The effect of temperature on modified kerosene is studied for viscosity, surface tension, specific heat, density and ignition delay. The time delay for ignition of gas-phase mixtures of modified kerosene/oxygen have been measured using a shock tube facility. The experiments are conducted in the temperature range of 1200–1877 K, pressure range of 4–12 atm and equivalence ratio of Ø = 1.5, 1 and 0.5. The ignition delay time measurements were carried out using piezoelectric pressure transducers, which records the pressure rise due to ignition and simultaneously recording the light emission during the process of ignition using a photodiode. The ignition delay is represented as τign = 0.168841 × P−1.49 × Ø0.72 × e(14310/T)

“…The thermal stabilities of RP-1 and, to a lesser extent, RP-2 have been thoroughly studied, particularly with respect to the conditions that lead to coking. − Studies of how thermal stressing affects the thermophysical properties of RP-1 and RP-2 are lacking, however. In an effort to address this disparity, a comprehensive study was undertaken at the National Institute of Standards and Technology (NIST).…”

Density, speed of sound, and viscosity have been measured for samples of RP-1 and RP-2 that were stressed for 0.5 min at 475 and 510 °C at a pressure of 17 MPa. Density and speed of sound were measured from 5 to 50 °C for samples stressed at 475 °C and from 5 to 35 °C for samples stressed at 510 °C. Viscosity was measured from −10 to 50 and 35 °C for the samples stressed at 475 and 510 °C, respectively. All measurements were made at ambient atmospheric pressure (∼83 kPa). Additionally, the density and sound speed data were used to derive adiabatic compressibilities, and those results have also been included. Current results for the thermally stressed samples were compared to previously reported measurement results for unstressed RP-1 and RP-2. For all reported properties, increased thermal stressing resulted in increased fuel decomposition and increased deviations from unstressed values.
