CATALYST FOR REMOVING CARBON MONOXIDE IN HYDROGEN RICH GAS ACCORDING TO WATER GAS SHIFT REACTION

摘要

A catalyst for removing carbon monoxide (CO) in a hydrogen rich gas accordin g to a water gas shift reaction is provided. This catalyst includes platinum a nd rhenium supported as catalyst metals on a rutile titania support. This catalyst provides a high CO conversion at a relatively low reaction temperature between 200 .Zcaron.and 300 .Zcaron. and is excellent in cost/performance due to a reduction in amount of supported platinum. It is preferred that a weight ratio of an amount of supported platinum to an amoun t of supported rhenium is in a range of 3:1 to 1:1, and particularly 3:2. For example, an apparatus using this catalyst is expected as a hydrogen source f or a fuel cell of generating electricity from a reaction between hydrogen and oxygen.
