Hydrolysis of carbon oxysulfide |
摘要 |
The hydrolysis of carbon oxysulfide is catalyzed by piperazinone and alkyl-substituted piperazinones at ambient or below ambient temperatures. The hydrolysis step can be combined with a sour gas purification process in the treatment of refinery gases, coal gasification streams, and other such gases which contain COS and other acidic contaminants.
