CO shift catalyst, method for producing the same, and CO shift reactor using CO shift catalyst

摘要

Disclosed is a CO shift catalyst for modifying carbon monoxide (CO) in a gas.  The CO shift catalyst contains one of platinum (Pt), ruthenium (Ru), iridium (Ir) and rhodium (Rh) or a mixture of these elements as an active component, while having a carrier composed of titanium (Ti), aluminum (Al), zirconium (Zr) or cerium (Ce) which is used for supporting the active component.  The CO shift catalyst can be applied to a halogen-resistant CO shift reactor (15) wherein CO in a gasified gas (12) produced in a gasification furnace (11) is converted into CO
