Storage stability. Part 3. Comparison of distillate fuel in storage
This brief one-page report summarizes part 3 of a 9-part cooperative program between the Bureau of Mines and the Western Petroleum Refiners Association (W.P.R.A.) to obtain storage stability data on distillate fuels that were representative of crude oil sources from major producing areas of the world. A total of 34 distillate fuels and 250 blends of these fuels were stored under several conditions - at 37.8/sup 0/C (100/sup 0/F) in glass bottles with contaminants (copper or iron, with or without water), at 43.3/sup 0/C (110/sup 0/F) in vented glass bottles with no contaminant, or at ambient temperature in 55-gallon vented steel drums. The fuels and blends in glass bottles were stored for periods of 6, 13, 26, or 39 weeks, while those in the drums remained in storage for one year. At the end of each storage period, a sample was removed for determination of light transmission, insoluble gum, and soluble gum. Straight-run fuels were found to be the most stable, catalytically cracked fuels were intermediate in stability, and thermally cracked fuels were the least stable. Oxidation appeared to be a major factor in gum formation. Copper catalyzed gum formation; storage of a fuel in contact with copper and sea water was the most severe storage condition studied. Iron had no effect on gum formation; however, some of the fuels were degraded by contact with galvanized iron and sea water.
