Fluid catalytic cracking process

摘要

One exemplary embodiment can be a fluid catalytic cracking process. The process can include a reaction zone operating at conditions to facilitate olefin production and including at least one riser. The at least one riser can receive a first feed having a boiling point of about 180° to about 800° C., and a second feed having more than about 70%, by weight, of one or more C4+ olefins.

1. A fluid catalytic cracking process, comprising:
operating a reaction zone at conditions to facilitate olefin production and comprising at least one riser; receiving in the at least one riser:
1) a first feed having a boiling point of about 180 to about 800° C.;2) a second feed comprising one or more C4+ olefins comprising more than about 10%, by weight, butenes; and3) a third feed comprising a naphtha stream including oligomers of butenes; wherein the third feed is injected downstream of the second feed.
