Abstract
Apparatus and methods which can remove, for example, mercury (Hg) from industrial flue gases. An exemplary sorbent polymer composite (SPC) can include a polymer, a sorbent which has a microstructure, and a transition metal halide in the microstructure. The transition metal halide can include silver (Ag), iodine (I), or both (AgI). A method for producing the SPC can include applying a non-halide salt of a transition metal to a sorbent, applying a non-transition metal halide to the sorbent, so as to react the non-transition metal halide with the non-halide salt of the transition metal, thereby forming a transition metal halide within the microstructure of the sorbent.

-44. (canceled)
A sorbent polymer composite (SPC), comprising:
- a polymer;
- and
- a sorbent,
- wherein the sorbent includes a microstructure
- wherein the microstructure comprises a transition metal halide.
A method, comprising:
- obtaining a sorbent polymer composite (SPC), wherein the SPC comprises a polymer and a sorbent;
- obtaining a non-halide salt of a transition metal;
- obtaining a non-transition metal halide;
- applying the non-halide salt of the transition metal to the sorbent, so as to incorporate the non-halide salt of the transition metal within a microstructure of the sorbent;
- and
- applying the non-transition metal halide to the sorbent, so as to react the non-transition metal halide with the non-halide salt of the transition metal, thereby forming a transition metal halide within the microstructure of the sorbent.
A method, comprising:
- obtaining a sorbent polymer composite (SPC), wherein the SPC comprises:
- a transition metal halide, and
- sulfur;
- and
- flowing a gas comprising mercury to contact the SPC, whereby mercury sulfide (HgS) is formed by a catalytic reaction of the mercury and the sulfur wherein the transition metal halide acts as a catalyst.
