Abstract
An apparatus for stripping gases from catalyst material comprises baffles having a second face that extends toward a downcomer channel between baffles to spread catalyst out on adjacent baffles for better contact with stripping gas.
Claims20
An apparatus for the stripping of entrained and/or adsorbed hydrocarbons from catalyst particles, said apparatus comprising:
- a stripping vessel;
- at least one port defined by the stripping vessel for receiving catalyst particles that contain entrained or adsorbed hydrocarbons;
- a first baffle and a second baffle spaced apart vertically over at least a portion of the stripping vessel, said first and second baffles defining a downcomer channel therebetween and said first baffle including a first face and a second face angled with respect to vertical and each other;
- a fluid inlet for passing a stripping fluid to the underside of said first and second baffles for stripping hydrocarbons from the particulate material;
- and
- a particle outlet for recovering stripped particles from the first and second baffles.

An apparatus for the stripping of entrained and/or adsorbed hydrocarbons from catalyst particles, said apparatus comprising:
- a stripping vessel;
- at least one port defined by the stripping vessel for receiving catalyst particles that contain entrained or adsorbed hydrocarbons;
- a first baffle and a second baffle spaced apart vertically over at least a portion of the stripping vessel, said first baffle including two faces angled with respect to vertical and angled with respect to each other, said second face of said first baffle extending into said downcomer channel;
- a fluid inlet for passing a stripping fluid to the underside of said first and second baffles for stripping hydrocarbons from the particulate material;
- and
- a particle outlet for recovering stripped particles from said first and second baffles.

An apparatus for catalytically cracking larger hydrocarbons into smaller hydrocarbons comprising:
- a reactor riser in which catalyst is contacted with feed comprising larger hydrocarbons to produce smaller hydrocarbons;
- a reactor vessel in which catalyst and hydrocarbons are separated;
- a stripping vessel in which entrained and/or adsorbed hydrocarbons are stripped from catalyst particles comprising at least one port defined by the stripping vessel for receiving catalyst particles that contain entrained or adsorbed hydrocarbons, a first baffle and a second baffle spaced apart vertically over at least a portion of the stripping vessel, said first and second baffles defining a downcomer channel therebetween and said first baffle including a first face and a second face angled with respect to vertical and each other, said second face extending from said first face into said downcomer channel, a fluid inlet for passing a stripping fluid to the underside of said first baffle for stripping hydrocarbons from the catalyst particles, and a particle outlet for recovering stripped catalyst particles from the first and second baffles;
- and
- a regenerator for regenerating stripped catalyst particles.
