Catalyst and process for removal of sulphur compounds and oxides from fluid streams |
| abstract |
The invention comprises a regeneratable catalyst that is capable of providing a reactive oxygen to partially oxidize sulphur-containing compounds to produce sulphur. It includes a method for removing sulphur compounds including both sulphur oxides and hydrogen sulphide from a fluid stream and decomposing such compounds to produce sulphur. Sour natural gas can be sweetened effectively by this invention, and sulphur can be prepared thereby. The catalyst is preferably formed by impregnating alkali metal sulfide and sulfide(s) or selenide(s) of metal(s) showing polyvalent and/or amphoteric character, e.g. Zn, etc. on a microporous type support (e.g., alumina). Its activity is sustained by exposure to a source of oxygen, such as air, oxygen sulphur dioxide or nitrogen peroxide and the like. A method is also described by which sulphur dioxide may be absorbed from flue gas and converted to sulphur, while higher oxides of nitrogen and carbon dioxide are being absorbed for subsequent recovery, utiliz-ing a catalyst that has been conditioned by prior exposure to a reducing gas. |
