GENERATION OF MODEL-OF-COMPOSITION OF PETROLEUM BY HIGH RESOLUTION MASS SPECTROMETRY AND ASSOCIATED ANALYTICS

摘要

A method to determine the model-of-composition of a vacuum resid in which the resid is separated into fractions including the DAO fraction which is then separated into chemical classes including saturates, aromatics, sulfides and polars by a combination of soft ionization methods. The results of the ionization analyses are reconciled with other analyses such as bulk analysis, then consolidated to generate the modeol-of composition.
