COS转化催化剂的催化剂再生方法
摘要：
本发明相关的COS转化催化剂的催化剂再生方法是对碳原料进行气化，并对气化气体中的羰基硫(COS)进行水解的Ba/TiO2类COS转化催化剂的再生方法，将使用后的COS转化催化剂用水清洗后干燥，接着于钡盐水溶液中浸渍处理规定时间，干燥后实施烧结处理，从而可以在COS转化催化剂的表面再次担载活性成分，再生COS转化催化剂。
摘要（英）：

This catalyst regeneration method for a COS conversion catalyst is a regeneration method for a Ba/TiO2 COS conversion catalyst for hydrolyzing carbonyl sulfide (COS) in gasified gases in which a carbon starting material is gasified. Used COS conversion catalyst is dried after water washing, immersed in an aqueous solution of a barium salt for a prescribed period of time, and fired after drying. Thereby, it is possible to make the COS conversion catalyst carry an active component again on the surface thereof and thus regenerate the COS conversion catalyst.
