This patent describes improvement in a process for regenerating a cracking catalyst by introducing an oxygen-containing gas into a fluidized bed of cracking catalyst particles through nozzles arranged on the sidewalls of a generally horizontally positioned grid of supply lines, wherein each one of nozzles has a length which is less than the outside diameter of the supply line. The improvement comprises: introducing the oxygen containing gas into the fluidized bed through a nozzle arrangement wherein a minor portion of nozzles on the sidewalls of the grid of the supply lines have a length greater than the outside diameter of the supply lines and a major portion of nozzles on the sidewalls of the grid of the supply lines have a length less than the outside diameter of the supply lines.
