CO SHIFT CATALYST, CO SHIFT REACTOR, AND METHOD FOR PURIFYING GASIFICATION GAS

摘要

Provided is a CO shift catalyst that reforms carbon monoxide (CO) in a gas. The CO shift catalyst includes an active component containing either molybdenum (Mo) or iron (Fe) as a main component, and either nickel (Ni) or ruthenium (Ru) as an accessory component, and a carrier which carries the active component and consists of one or two or more kinds of oxides of titanium (Ti), zirconium (Zr), and cerium (Ce). A temperature during catalyst manufacturing firing is set to 600°C or higher, and an average pore size of the carrier is set to 300 Å or more.
