Abstract
An apparatus is disclosed for catalytically converting two feed streams. The feed to a first catalytic reactor may be contacted with product from a second catalytic reactor to effect heat exchange between the two streams and to transfer catalyst from the product stream to the feed stream. The feed to the second catalytic reactor may be a portion of the product from the first catalytic reactor.
Claims20
A catalytic cracking apparatus comprising:
- a first catalytic reactor in communication with a wash column;
- a second catalytic reactor in communication with said first reactor;
- and
- said wash column in communication with said second reactor and said wash column is in direct downstream communication with a first hydrocarbon feed line, wherein said first hydrocarbon feed line is out of downstream communication with said first catalytic reactor and said second catalytic reactor.
1 more element
A catalytic cracking apparatus comprising:
- a first catalytic reactor in direct communication with a wash column through a line that exits a bottom of said wash column;
- a main fractionation column in communication with said first catalytic reactor;
- a second catalytic reactor in communication with said main fractionation column;
- and
- said wash column in communication with said second reactor and said wash column is in downstream communication with a first hydrocarbon feed line.

A catalytic cracking apparatus comprising:
- a first catalytic reactor in direct downstream communication with a wash column;
- a debutanizer column in communication with said first catalytic reactor;
- a naphtha splitter column in communication with said debutanizer column;
- a second catalytic reactor in communication with said naphtha splitter column;
- and
- said wash column in communication with said second reactor and said wash column is in direct downstream communication with a first hydrocarbon feed line, wherein said first catalytic reactor is in direct downstream communication with said wash column through said first hydrocarbon feed line from the bottom of said wash column.
