Abstract
A reduction in the formation and presence of peroxides in low sulfur diesel fuels is obtained through the combination of those fuels with an organic nitrate combustion improver. The reduction in the amount of peroxides means that the fuel system elastomers will be more durable, as they are not being corroded by as much peroxide formed in the fuel, fuel color durability is improved, fuel stability is enhanced, and fuel sediments are reduced.
Claims8
A method of reducing the amount of peroxides in low sulfur, middle distillate fuels comprising the steps of:
- providing a middle distillate fuel having a sulfur content of about 50 ppm or less;
- combining the fuel with an organic nitrate combustion improver;
- maintaining the combined fuel and organic nitrate combustion improver at a temperature below 70 degrees Celsius;
- wherein the amount of organic nitrate combustion improver combined with the fuel reduces the amount of peroxides in the fuel as compared with a middle distillate fuel without the organic nitrate combustion improver.
