Abstract
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 analysis are reconciled with other analysis such as bulk analysis, then consolidated to generate the modeol-of composition.
