Process and apparatus for regenerating catalyst

A catalyst regenerator vessel for combusting carbonaceous deposits from catalyst comprising:

• a combustion gas distributor in fluid communication with a combustion gas line for introducing a combustion gas to said vessel;
• a catalyst pipe with a first opening and a second opening, said catalyst pipe feeding a catalyst distributor being attached to said catalyst pipe, the catalyst distributor comprising:
• a first header in fluid communication with said first opening in said catalyst pipe for distributing catalyst to said vessel, an angular nozzle in said first header projecting at an angle to a longitudinal axis of said first header for distributing catalyst into said vessel;
• a separator in communication with said regenerator vessel for separating gas from said catalyst;
• and
• a regenerated catalyst outlet for discharging regenerated catalyst from said vessel.

A process for combusting coke from catalyst comprising:

• delivering coked catalyst from a catalyst pipe to a catalyst distributor, said catalyst distributor comprising:
• a first header in fluid communication with a first opening in said catalyst pipe for distributing catalyst to said vessel, an angular nozzle in said first header projecting at an angle to a longitudinal axis of said first header for distributing catalyst into said vessel;
• discharging catalyst from said catalyst distributor from at least two sides of said catalyst pipe into a regenerator vessel;
• delivering combustion gas to said regenerator vessel for combusting coke from said catalyst to produce flue gas and regenerated catalyst;
• separating said flue gas from said regenerated catalyst;
• and
• discharging regenerated catalyst from said regenerator vessel.
