Abstract
Herein is provided mercury sorbent compositions and methods for their manufacture. In embodiments, the mercury sorbent compositions can include calcium metal sulfides (CaxMySz), where M can be Cr, Mn, Fe, Co, Ni, Cu, Zn, or a mixture thereof where x can have a value from about 0.1 to about 5; where y can have a value of about 1, and where z can have a value of about 1 to about 10. In one example, the mercury sorbent composition can have the formula: Cax(Fe1-yCuy)Sz. In other embodiments, the mercury sorbent compositions can include copper sulfide carbonates (e.g., CuxSy(C03)z; wherein x can have a value from about 1 to about 5, y can have a value from about 1 to about 10, and z can have a value from about 0.1 to about 2.5. In one example, the mercury sorbent compositions can have the formula CuSx(CO3)y.
