Reactivity of the saturated, aromatic and resin fractions of ATR resids under FCC conditions

- SARA fractions from a naphthenic crude were converted on FCC catalysts.
- SARA fractions produce hydrocarbons in the same range as VGO feedstocks.
- Yields of the hydrocarbon groups from the various fractions reveal their nature.
- Yields from a resid are not the direct addition of the yields from the SARA fractions.
- CREC Riser Simulator reactor confirmed as a proper tool for FCC related studies.
