Process for recovering products from two reactors

摘要

A process 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.

主权项

1. A fluid catalytic cracking process, comprising:
contacting a first hydrocarbon feed in route to a first fluid catalytic cracking reactor with a second hydrocarbon product from a second fluid catalytic cracking reactor to preheat the first hydrocarbon feed and cool the second hydrocarbon product; contacting said first hydrocarbon feed with catalyst to provide a first cracked product; transferring said first cracked product to a first product recovery section; and directing said second hydrocarbon product to a second product recovery section.
