Carbon deposition from thermal stressing of several jet fuel samples, hydrotreated petroleum- and coal-derived liquids and their blends, and Norpar-13 on an Inconel 718 surface when heated to a fluid temperature of 470°C at 35 atm in an essentially isothermal flow reactor was studied. Hydrotreated (HDT) LCO, JP-7, Jet A, and commercial solvent Norpar-13 produced relatively low masses of carbon deposits after the 24 hr stressing. Further hydrogenation/hydrotreatment of HDT-LCO to produce SAT-LCO increased its tendency to produce carbon deposit. The blended (50:50 vol) SAT-LCO/RCO and HDT-LCO/RCO produced carbon deposits similar in quantities obtained from the thermal stressing of the JP-8 fuel samples. Hydrocarbon composition of the fuels and the constituent sulfur species played major roles on how a metal alloy surface behaves from incipient nucleation to accumulation of massive deposits.
