Abstract
Sulfur compounds in diesel exhaust diminish the performance of aftertreatment devices and contribute to particulate matter mass and composition. Sulfur sorbate catalysts that store and release sulfur compounds have been used in conjunction with NOx aftertreatment catalysts to decrease the negative effects of sulfur.1 The temperature range of diesel exhaust is broad and may vary with application. The effect of temperature on the performance of sulfur catalysts will determine the usefulness of such catalysts for diesel applications. In this study bench reactor and engine testing of sulfur sorbate catalysts were performed to characterize the release of sulfur compounds as a function of temperature. Engine tests were performed on a lightduty platform with No. 2 Diesel fuel.
