Abstract
A method may include: contacting a feed stream comprising carbonyl sulfide with an aqueous stream comprising water in the presence of a carbonyl sulfide hydrolysis catalyst, wherein the carbonyl sulfide hydrolysis catalyst comprises a solid support and a polyamine covalently bonded to the solid support; and hydrolyzing at least a portion of the carbonyl sulfide to produce at least hydrogen sulfide.
Claims20
A method comprising:
- contacting a feed stream comprising carbonyl sulfide with an aqueous stream comprising water in the presence of a carbonyl sulfide hydrolysis catalyst, wherein the carbonyl sulfide hydrolysis catalyst comprises a solid support and a polyamine covalently bonded to the solid support;
- and
- hydrolyzing at least a portion of the carbonyl sulfide to produce at least hydrogen sulfide.
A method comprising:
- introducing carbonyl sulfide and an aqueous liquid into a vessel comprising a carbonyl sulfide hydrolysis catalyst;
- and
- hydrolyzing at least a portion of the carbonyl sulfide to produce at least hydrogen sulfide;
- wherein the carbonyl sulfide hydrolysis catalyst comprises a solid support and a polyamine covalently bonded to the solid support and wherein the vessel comprises at least one of a distillation column, a contacting tower, or a fiber bundle type liquid-liquid contactor.

A method of producing a carbonyl sulfide hydrolysis catalyst comprising:
- providing a solid support comprising an oxygen containing functional group;
- mixing the solid support with a polyamine;
- and
- reacting at least a portion of the polyamine with the solid support to form a covalent bond between the polyamine and the solid support, thereby forming the carbonyl sulfide hydrolysis catalyst.
