Abstract:
The present invention is generally related to the analysis of chemical compositions of hydrocarbons and hydrocarbon blends. This method, in particular embodiments, may apply specifically to the problem of analyzing extremely complex hydrocarbon-containing mixtures when the number and diversity of molecules makes it extremely difficult or impossible to realistically identify and quantify them individually in a reasonable timeframe. Particular SEC (size exclusion chromatography)-based methods and apparatus disclosed herein may be used to measure, e.g., the molecular size, weight, and/or volume, whether in absolute or relative manner, of the various components of eluate from the SEC stationary phase (e.g., a permeable gel). This analytical method is applicable on a wide variety of hydrocarbonaceous materials, and especially useful for, but not limited to oil, maltenes of oil, asphalt binders and asphalt binder blends, which may contain wide varieties of different types of additives, modifiers, and chemistries.

Claim (Index 8):
A method as described in  claim 7  wherein said step of dissolving at least a portion of said precipitated asphaltenes with said material dissolving solvent comprises the step of dissolving substantially all of said precipitated asphaltenes using a successive dissolution procedure where material dissolving solvents of increasing strength are successively passed over said precipitated asphaltenes, each dissolving a different portion thereof, and each generating a different additional eluate.
