Abstract
A process and apparatus described is for distributing hydrocarbon feed to catalyst in a riser. Hydrocarbon feed is delivered to a plenum in the riser. Nozzles from the plenum inject feed into the riser to contact the catalyst. Streams of regenerated catalyst and carbonized catalyst may be passed to the riser and mixed around an insert in a lower section of a riser. The plenum may be located in the riser.
Claims17
An apparatus for fluid catalysis comprising:
- a riser;
- a plenum located in an radial center of said riser;
- and
- a nozzle in said plenum with an outlet end directed away from said radial center for injecting hydrocarbon feed, wherein said nozzle is disposed tangentially with respect to an outer wall of said plenum.

An apparatus for fluid catalysis comprising:
- a riser;
- an insert in said riser defining a space between a wall of said riser and a wall of said insert, an opening to a chamber inside said insert;
- a nozzle in said insert for injecting hydrocarbon feed, an outlet end of said nozzle being disposed in said chamber;
- a first catalyst inlet in communication with the riser;
- a second catalyst inlet in communication with the riser;
- and
- said insert in said riser between said first catalyst inlet and said second catalyst inlet.
4 more elements
An apparatus for fluid catalysis comprising:
- a riser;
- an insert in said riser defining a space between a wall of said riser and a wall of said insert, said insert having a dished top with nozzles in the top for injecting hydrocarbon feed;
- a first catalyst inlet in communication with the riser;
- a second catalyst inlet in communication with the riser;
- and
- said insert in said riser is between said first catalyst inlet and said second catalyst inlet and said nozzle is disposed at a higher elevation than said first catalyst inlet and said second catalyst inlet.
