    • The 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 may be prepared by contacting a catalyst support, such as silica, with a solution containing ammonium metal salts, such as ammonium iron citrate and ammonium zinc citrate, and an amount of chloride (e.g., ammonium chloride) that is between about 0.1 and about 20 weight percent of the metal ions in the solution, to produce a support material impregnated with ammonium metal citrate salts and ammonium chloride. This impregnated catalyst support is then dried and calcined to produce a catalyst, such as iron and zinc oxide mixture supported on silica. It has been found that by adding chloride to the impregnated catalyst support prior to calcination and drying, that the sintering of the metal oxides can be controlled and the formation of a mixed metal oxide is promoted. It has also been found that the catalyst of the invention exhibits improved selectivity characteristics when compared to a catalyst prepared without the chloride.
    • 本发明提供催化剂; 制备催化剂的方法和使用该催化剂促进硫化氢选择性氧化成元素硫的方法。 催化剂可以通过使催化剂载体如二氧化硅与含有铵金属盐(例如柠檬酸铁铵和柠檬酸铵锌)的溶液以及一定量的氯化物(例如氯化铵)接触来制备,所述氯化物(例如,氯化铵)在约0.1和 约20重量%的溶液中的金属离子,以产生浸渍有铵金属柠檬酸盐和氯化铵的载体材料。 然后将该浸渍的催化剂载体干燥并煅烧以产生催化剂,例如负载在二氧化硅上的铁和氧化锌混合物。 已经发现,通过在煅烧和干燥之前向浸渍的催化剂载体中加入氯化物,可以控制金属氧化物的烧结并促进混合金属氧化物的形成。 还已经发现,与不用氯化物制备的催化剂相比,本发明的催化剂表现出改进的选择性特性。
