Abstract
Processes and systems are disclosed for improving the yield from reforming processes. Aromatic complex bottoms, or a heavy fraction thereof, are subjected to catalytic conversion to produce additional gasoline and higher-quality aromatic compounds.
Claims28
A process for treatment of C9+ aromatic complex bottoms obtained from catalytic reforming of naphtha followed by separation in an aromatic complex into a gasoline pool stream, an aromatic products stream and the C9+ aromatic complex bottoms, the process comprising:
- reacting a feedstream comprising all or a portion of the C9+, C10+ or C11+ aromatic bottoms in the presence of a catalyst under specified fluidized catalytic cracking reaction conditions to produce an FCC naphtha stream, light olefins and cycle oil.
A process for treatment of C9+ aromatic complex bottoms obtained from catalytic reforming of naphtha followed by separation in an aromatic complex into a gasoline pool stream, an aromatic products stream and the C9+ aromatic complex bottoms, the process comprising:
- separating all or a portion of the C9+ aromatic bottoms into a tops fraction and a bottoms fraction;
- and
- reacting a feedstream comprising all or a portion of the bottoms fraction in the presence of a catalyst under specified fluidized catalytic cracking reaction conditions to produce an FCC naphtha stream, light olefins and cycle oil.
A system comprising:
- a catalytic reforming zone having an inlet in fluid communication with a source of naphtha, a first outlet for discharging a gas stream containing hydrogen, and a second outlet for discharging reformate;
- an aromatic complex having an inlet in fluid communication with the second outlet for discharging reformate, a first outlet for discharging a gasoline pool stream, a second outlet for discharging an aromatic products stream, and a third outlet for discharging C9+ aromatic complex bottoms;
- and
- a fluidized catalytic cracking (FCC) zone having an inlet in fluid communication with the third outlet for discharging C9+ aromatic complex bottoms, a first outlet for discharging gases including light olefins, a second outlet for discharging an FCC naphtha stream, and a third outlet for discharging cycle oil.
