  • Regeneration of solid absorbant fuel stability enhancing material
    Patent number: H1071
    Abstract: Liquid hydrocarbon fuels such as diesel fuel and aviation jet fuel are stabilized by insertion of solid porous stabilizing foam into storage tanks. Fuel-insoluble particles resulting from degradation of the fuel which form during prolonged storage are absorbed by the foam. The absorbed particles are removed from the foam by contacting it with a polar solvent. The foam thus regenerated is re-used for continued stabilization of stored liquid hydrocarbon fuels. The polar solvent having fuel-insoluble particles dissolved therein is recovered by distillation for re-use.
