Abstract
An adsorbent composition for capturing pollutants includes a porous composition that includes a plurality of ferric oxyhydroxide particles and an additional component in the porous composition. The additional component includes one of copper chloride (CuCl2), zinc chloride (ZnCl2), polyvinylpolypyrrolidone, silicon carbide, silicon dioxide, activated carbon or other carbonaceous material, and a combination thereof.

A process of capturing hydrogen sulfide in a contaminated feed stream, comprising:
- providing the contaminated feed stream that includes hydrogen sulfide to an inlet of an adsorption apparatus containing a porous composition comprising ferric oxyhydroxide particles;
- providing optimal contact between the porous composition and the contaminated feed stream to produce treated feed stream;
- and
- allowing the treated feed stream to exit through an outlet of the adsorption apparatus.
