Development of High Stability Fuel.
Abstract
The study of oxygenated trace impurities on the stability of Humble JP-5 was extended to include a typical aliphatic-aromatic ester, (methyl benzoate) an aliphatic ester (phenyl formate) an aliphatic alcohol (n-dodecyl alcohol) and a ketone (5-nonanone). All were evaluated in deoxygenated Humble JP-5 at the 100 PPM 0 level. Hexanoic, was also investigated. Six new diolefins were evaluated in a deoxygenated synthetic 4-component blend. This blend consisted of 25% (by weight) of n-dodecane, 25% of 2,2,5-trimethylhexane, 30% of isopropylcyclohexane and 20% of secbutylbenzene. The results confirm the previous observations that structural features play an important part in determining the influence of olefins on deposit formation. A representative substituted acetylene, 1-decyne, was also tested in the 4-component synthetic blend. Two condensed ring hydrocarbons, indan and tetralin, were tested in a new 4-component blend. Scanning electron microscope studies of deposit morphology were extended to pure hydrocarbon blends containing various amounts of dissolved oxygen. A survey of the use of acid washing, caustic washing and absorbents in refining of jet fuel was conducted to determine the possible changes in trace impurity content brought about by such processing steps.
