Abstract:
1. A process for increasing color quality and thermal stability of a jet fuel, comprising: providing the jet fuel, wherein the jet fuel has an ASTM D86 10% boiling point from about 110° C. to about 190° C., an ASTM D86 90% boiling point from about 200° C. to about 290° C.; and a Saybolt color of not greater than 20; and contacting the jet fuel with an acidic, ion-exchange resin thereby increasing the color quality of the jet fuel by at least 10% in accordance with ASTM D156 and increasing the thermal stability of the jet fuel by at least 10% in accordance with ASTM D3241; wherein the provided jet fuel is treated to reduce mercaptan content prior to contact with the acidic, ion-exchange resin.
