Abstract
An S storage catalystis equipped with a catalytic supporter, a catalytic metal being supported on this catalytic supporter and oxidizing SOto SO, and an S storage material being supported on the catalytic supporter and storing S components therein. This S storage catalysthas an exhaust-gas-inlet-side high-concentration portionA in which the S storage material is supported on the catalytic supporter in a high concentration, and an exhaust-gas-outlet-side low-concentration portionA in which the S storage material is supported on the catalytic supporter in a low concentration that is lower than that of the high-concentration portion. In accordance with this S storage catalyst, it is possible to maintain the S storing performance favorably, even in a case where exhaust-gas temperatures are low, while keeping the material cost from rising steeply.
