Abstract:
1. 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.
