Patent ID: 7217401

Claim:
A method for reducing the amount of mercury affixed to a sorbent, the method comprising: providing an amount of sorbent, at least a portion of the amount of sorbent comprising particulates having mercury compounds affixed to the particulates; depositing the amount of sorbent on a floor of a fluidized bed conveyor, the floor comprising a metal media having openings; passing heated flowing air through the openings to move the amount of sorbent from a beginning to an exit area of the fluidized bed conveyor; measuring an in process temperature of the sorbent when the sorbent is exposed to the heated flowing air; removing at least a portion of the sorbent being exposed to the heated flowing air when the measured in process temperature reaches a temperature in the range of 700° F. to 1000° F.; thereafter providing a second amount of sorbent, at least a portion of the second amount of sorbent comprising particulates having mercury affixed to the particulates; and thereafter maintaining the sorbent in the heated flowing air until the sorbent reaches a temperature in the range of 700° F. to 1000° F., wherein the fluidized bed conveyor is an air slide.
