摘要: Hydrolysis of COS in gas streams to H.sub.2 S and CO.sub.2 can be improved by using certain bicyclo tertiary amine catalysts. Bicyclo tertiary amine catalysts can enhance COS hydrolysis in an acid gas removal solvent in the liquid phase or on a solid support system in the gas phase.
摘要翻译: 通过使用某些双环叔胺催化剂可以改善气流中的COS对H 2 S和CO 2的水解。 双环叔胺催化剂可以在液相中的酸性气体去除溶剂中或在气相中的固体支持体系上增强COS水解。
