The various embodiments of the invention relates to the composition of matter of a hydrogen sulfide sorption material and the related method of manufacture and method of use. The Capture Material is manufactured from steel or iron solubilized with hydrochloric acid. The resulting iron chloride solution is treated with caustic solution to increase the pH, and then further neutralized with lime. Prior to filtration, a flocculent is used to aid in the separation of the Capture Material. After filtration, the Capture Material is dried, crushed, and screened to an appropriate mesh size and packaged. The Capture Material is used by charging standard sorption towers and allowing hydrogen sulfide laden gas or vapor to flow through a bed of the Capture Material. The Capture Material thereby chemically and physically sorbs the hydrogen sulfide and removing the hydrogen sulfide from the gas or vapor exiting the sorption tower.
A hydrogen sulfide capture material comprising
A hydrogen sulfide capture material having a structure that is comprised of Fe(OH)3, wherein the capture material is formed by solubilizing an iron source in acid to form an aqueous solution comprising iron chloride, neutralizing the aqueous solution with a caustic solution to form a neutralized solution, washing the neutralized solution to separate the neutralized solution into water and a slurry, forming a thickened slurry by removing additional water from the slurry, separating the thickened slurry to produce filtered water and a wet filter cake, and drying the wet filter cake to form granules.
A method for making a hydrogen sulfide capture material, the method comprising the steps of:
