Summary:

A two-chamber catalyst system for the aftertreatment of No. 2 Diesel exhaust is demonstrated. NOx conversion efficiencies greater than 95% were obtained over a broad range of operating temperatures and NOx levels. The system incorporates a NOx catalyst (SCONOx) for the removal of CO, hydrocarbons, and NOx from the exhaust stream and a SO2 catalyst (SCOSOx) for the protection of the NOx catalyst from sulfur poisoning. Both catalysts are of sorbate or "trap" type. Hydrogen is used as the reductant and can be supplied by on-board fuel reformers. Tests of the catalysts were performed with various loads, temperatures, and NOx levels. A light-duty diesel engine with no particulate control was used for the tests. All tests were conducted using No. 2 Diesel fuel
