Influence of the nature of FCC feed on the production of light olefins by catalytic cracking
- Institut Francais du Petrole, Rueil-Malmaison (France)
The 1990 Clean Air Act has act rules for gasoline reformulation, which requires major compositional changes, Including a higher contribution of oxygenated compounds to the gasoline pool. This explains why FCC units are expected to play a major role in the coming years as a producer of light olefins (propylene, butenes and amylenes) to be used as feedstock for oxygenate (MTBE/TAME) production. The impact of the nature of FCC feedstock on light olefins production (C3 to C5 olefins) has been studied using a MAT unit running at various operating conditions (C/O ratio, reactor temperature). Paraffinic feeds are potentially efficient to produce light olefins by catalytic cracking. Heavier paraffinic feeds like mixtures VGO + reside and pure reside have also been evaluated, and compared to naphthenic and aromatic feeds.
