WIPO Patent Application WO2004069964

A3

The present invention relates to a stable blended diesel fuel comprising an olefinic diesel fuel blending stock. The olefinic diesel fuel blending stock of the invention comprises olefins in an amount of 2 to 80 weight percent, non-olefins in an amount of 20 to 98 weight percent wherein the non-olefins are substantially comprised of paraffins, oxygenates in an amount of at least 0.012 weight percent and sulfur in an amount of less than 1ppm. To provide acceptable stability, the blended diesel fuel comprising the olefinic diesel fuel blending stock comprises a sulfur-free antioxidant. The blended diesel fuel comprising the olefinic diesel fuel blending stock and sulfur-free antioxidant added has a peroxide content of less than 5 ppm when stored at 60°C for 4 weeks. The present invention also relates to processes for making the stable blended diesel fuel and olefinic diesel fuel blending stocks as defined above.
