Abstract
Official abstract text for this publication.
This invention relates to a method for increasing thermal stability of fuel, as well as in reducing nitrogen content and/or enhancing color quality of the fuel. According to the method, a fuel feedstock can be treated with a solid phosphoric acid catalyst under appropriate catalyst conditions, e.g., to increase the thermal stability of the fuel feedstock. Preferably, the fuel feedstock can be treated with the solid phosphoric acid catalyst at a ratio of catalyst mass within a contact zone to a mass flow rate of feedstock through the zone of at least about 18 minutes to increase the thermal stability of the fuel feedstock, along with reducing nitrogen content and/or enhancing color quality.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for increasing thermal stability of fuel, comprising: flowing a jet fuel feedstock through a contact zone containing solid phosphoric acid catalyst within the contact zone, wherein the jet fuel feedstock has an initial and final boiling point within a range from about 90° C. to about 360° C. (194° F. to about 680° F.), and wherein the jet fuel feedstock is in contact with the solid phosphoric acid catalyst for a period of time of at least about 18 m…
