Latest Patents

Terörde holds a patent for a catalyst and method for the selective oxidation of sulfur compounds to elemental sulfur. This invention provides a catalyst, a method for making the catalyst, and a method for using the catalyst to promote the selective oxidation of hydrogen sulfide into elemental sulfur. The catalyst is prepared by contacting a catalyst support, such as silica, with a solution containing ammonium metal salts, including ammonium iron citrate and ammonium zinc citrate. The process involves adding an amount of chloride, such as ammonium chloride, that ranges from about 0.1 to about 20 weight percent of the metal ions in the solution. This results in a support material that is impregnated with ammonium metal citrate salts and ammonium chloride. The impregnated catalyst support is then dried and calcined to produce a catalyst, such as an iron and zinc oxide mixture supported on silica. The addition of chloride prior to calcination and drying has been found to control the sintering of the metal oxides and promote the formation of a mixed metal oxide. The catalyst exhibits improved selectivity characteristics compared to those prepared without chloride.
