Process and apparatus for distributing fuel and air to a catalyst regenerator

A process for regenerating catalyst from a catalytic reaction comprising:

• providing a spent catalyst stream;
• distributing an oxygen gas stream to said spent catalyst stream through oxygen nozzles;
• generating an oxygen gas jet from said oxygen nozzles, wherein said oxygen nozzles are directed downwardly;
• distributing a fuel gas stream to said spent catalyst stream through a fuel nozzle;
• generating a fuel gas jet from said fuel nozzle, said fuel gas jet and said oxygen gas jet having the same elevation;
• and
• combusting said fuel gas stream and carbon on said spent catalyst with the oxygen gas stream to provide flue gas and regenerated catalyst.

A process for regenerating catalyst from a catalytic reaction comprising:

• providing a spent catalyst stream;
• distributing an oxygen gas stream to said spent catalyst stream through an oxygen outlet of an oxygen nozzle;
• generating an oxygen gas jet from said oxygen nozzle;
• distributing a fuel gas stream to said spent catalyst stream through a fuel outlet of a fuel nozzle;
• generating a fuel gas jet from said fuel nozzle, said fuel gas jet and said oxygen gas jet having the same elevation;
• and
• combusting said fuel gas stream and carbon on said spent catalyst with the oxygen gas stream to provide flue gas and regenerated catalyst
• wherein said fuel outlet of said fuel nozzle is located below an oxygen outlet of said oxygen nozzle.
