Abstract:
Methods are provided for qualifying jet fuel fractions that are derived at least in part from pre-refined crude oil sources. The methods allow for determination of the stability of a jet fuel product over time by using an accelerated aging test. The methods are beneficial for verifying the stability of a jet fuel fraction that includes a portion derived from a pre-refined crude oil.

Abstract:
Permselective separation of aromatic hydrocarbons from non-aromatic hydrocarbons in a feed stream is accomplished using improved asymmetric membranes. The preferred membranes are fashioned from a polyimide and conditioned with a lubricating oil. Feed streams containing a mixture of aromatic and non-aromatic hydrocarbons are contacted with the dense active layer side of the polyimide membrane under a pressure and temperature sufficient to selectively permeate the desired aromatic hydrocarbon.
