SYSTEM AND METHOD FOR REACTIVATING AND PELLETIZING SORBENTS FOR GAS CAPTURING
The present invention uses spray of water to reactivate spent sorbent by hydration and simultaneously produce the reactivated sorbent in pelletized form. The use of spray water combined with movement of the sorbent can be controlled to produce reactivated sorbent of desirable size. The system and method eliminate the need for separate pelletization after reactivation of spent sorbent, and allow both to complete in one process and in one container. The system and method enable addition of calcium aluminate cements as coating to form pellets with core-in-shell structure thereby enhancing pellet strength and sorbent capacity for absorbing gas.
