Summary
-
1.
It has been established experimentally that the changes in acidity of gasolines, jet fuels, and diesel fuels during storage at temperatures of 20 to 50°C are subject to relationships that are characteristic for first-order reactions.
-
2.
The average temperature coefficients of the oxidation rate constants for gasolines, jet fuels, and diesel fuels are all essentially the same within the range of temperatures investigated.
-
3.
Feasibility has been demonstrated for the prediction of changes in fuel acidity on the basis of storage tests at elevated temperatures (40–60°C).
