High temperature hydrogen sulfide removal with tin oxide
- TDA Research, Inc., Wheat Ridge, CO (United States)
This Phase II SBIR contract is developing a sorbent and process which removes H{sub 2}S from hot gasified coal and generates sulfur during regeneration of the sorbent. The process can be used with any type of reactor (e.g., fixed or moving bed) and any gasifier (e.g., KRW or Texaco) and shows lower costs that competing H{sub 2}S removal processes. TDA Research`s (TDA) process uses a regenerable stannic oxide-based (SnO{sub 2}) sorbent as the first sorbent and zinc ferrite (or zinc titanate) as a second sorbent to remove H{sub 2}S to very low concentrations. The process converts the sulfides from both sorbents to elemental sulfur, a commercial product which is easy to store and transport. The object of this phase is to develop chemically active, high sulfur loadings, and durable stannic oxide sorbents and to demonstrate the process at the bench scale.
