Abstract: Silver strip corrosion and copper strip corrosion of hydrogenated jet fuel caused by H2S were studied using four hydroprocessing jet fuel samples (from various crude oils, processing technologies and producers). Test results showed that there was no significant difference in the corrosion tests of these four samples without the presence of air, H2S content of hydrogenated jet fuel in the range of 0.10—0.50 μg/g and 0.50—1.00 μg/g could cause silver strip corrosion (Class 1) and copper strip corrosion (Class 1b), respectively. Storing or sunlight could greatly reduce the H2S corrosion of jet fuel, the class of silver strip corrosion and copper strip corrosion drops, especially for the latter.

Key words: jet fuel, hydrogen sulfide , silver strip corrosion , copper strip corrosion
