Abstract: Compositions and methods for the removal of hydrogen sulfide, vapor phase thiols, carbonyl sulfide, and combinations thereof, from gas/vapor streams are provided through the utilization of a regenerable formulated media. The compositions may include a bound complex treated-activated carbon media (BCT-AC media). The compositions and methods provide advantages over current known technologies by reducing the number of required process steps and resulting reduction in capital and operating costs, as well as elimination of aqueous phase processes that are expensive to operate and generate unwanted waste by products. Additionally, the compositions and methods provided remove hydrogen sulfide as recoverable elemental sulfur and are ideally suited for gas/vapor phase applications where carbon dioxide may be present as it has no process or economic impact on the compositions or methods.

Abstract: Solid absorbent compositions and methods for the removal of mercaptan sulfur compounds from hydrocarbon streams are provided. The compositions may include porous granulated activated carbon particles with internal pore surfaces containing bound trinuclear basic iron (III) acetate complex containing the [Fe3(?3-O)] core structure.
