ABSTRACT:
HCN is removed from a gaseous stream, e.g., a synthesis gas stream, by a two stage procedure in which the gaseous stream is first contacted with a specified oxygenated reactant composition to remove the bulk of the HCN, and then the gaseous stream is contacted with a polysulfide solution to reduce further the HCN content of the stream.
