    Abstract

    A combination of caustic treating and additives is used in the refinery to stabilize No. 2 distillate fuels to prevent the formation of insoluble gum and color degradation in long-term ambient storage. Cracked components are treated with caustic to remove reactive compounds such as thiophenols. Straight-run components are not treated. Blends of treated cracked components and untreated straight-run components can be further stabilized with commercial additives to limit insoluble gum formation to 2 mg/100 cm3 after storage for 16 weeks at 43.3°C.
