  • The actually used RP-3 jet fuel containing additives was employed as the study object to measure its density and the solubility of CO2 from 5℃ to 40℃ under three pressure ranges via a experiment apparatus based on the pressure reduction method. The experimental solubility was compared with the theoretical solubility calculated by a relative density method provided in the standard of ASTM D2780-92. The result reveals that there exists a large deviation between experimental solubility and the calculated solubility. The deviation rises with the increase of the temperature or the decrease of the pressure, and the maximum deviation is over 106%. Hence, the formula to calculate the Ostwald coefficient depicted in ASTM D2780-92 is linearly corrected via the experimental data and the deviation is within 10% after this correction. The study results can provide a reference for the design of the green on-board inert gas generation system.
