Processes for the continuous regeneration of a catalyst

A method for the continuous regeneration of a catalyst comprising:

• passing a catalyst from a reaction zone to a regeneration zone, wherein the regeneration zone includes at least a burn zone to remove coke from the catalyst;
• recycling the catalyst from the regeneration zone back to the reaction zone;
• and,
• further comprising at least one of the following:
• cooling the catalyst in a catalyst cooling zone after the catalyst exits the burn zone while the catalyst flows through a chloride, and,
• dispersing a metal on the catalyst with chloride in a chlorination zone after the catalyst has left the catalyst cooling zone;
• dispersing a metal on the catalyst in a chlorination zone of the regeneration zone,
• drying the catalyst in a catalyst drying zone of the regeneration zone and wherein catalyst drying zone receives a heated ambient oxygen,
• removing a portion of the heated ambient oxygen from the catalyst drying zone,
• passing the removed portion of the heated ambient oxygen to an oxygen heating zone,
• heating the removed portion of the heated ambient oxygen in the oxygen heating zone to provide a reheated ambient oxygen, and,
• passing the reheated ambient oxygen into the chlorination zone, and wherein a flow rate of the heated ambient oxygen is capable of being maintained while a flow rate of the reheated ambient oxygen is decreased;
• heating the catalyst in a catalyst heating zone so that a temperature of the catalyst has increased after the catalyst has flowed out of the burn zone,
• passing a heated ambient oxygen to the catalyst heating zone;
• and,
• removing a regeneration gas from the regeneration zone,
• recovering a chloride from the regeneration gas, and
• recycling the recovered chloride back to the regeneration zone.
