Abstract
A catalyst in the form of a honeycomb structured cordierite carrier having platinum supported in a loading weight of at least 0.20 mg per square centimeter of the apparent outer surface area of the catalyst is effective in a process for oxidizing CO in exhaust gas from a sintering furance wherein it maintains high CO oxidiation efficiency for a longer period of time, requiring less frequently regeneration and less power consumption.
