High temperature hydrogen sulfide removal with stannic oxide

摘要

This contract focuses on the development of sorbents and processes for removal of H(sub 2)S from hot coal gas with the product of sorbent regeneration being elemental sulfur. TDA Research's process uses a regenerable tin(IV) oxide-based (SnO(sub 2)) sorbent as the first sorbent and zinc ferrite (or zinc titanate) as a second sorbent.
