Abstract

A two-chamber catalyst system for the aftertreatment of No. 2 Diesel exhaust is demonstrated. NO_x conversion efficiencies greater than 90% were obtained over a broad range of operating temperatures and NO_x levels. The system incorporates a catalyst (SCONO_x™) for the removal of CO, hydrocarbons, and NO_x from the exhaust stream and a sulfur catalyst (SCOSOx™) for the protection of the NO_x catalyst from sulfur poisoning. Both catalysts are of sorbate or "trap" type. No. 2 Diesel and hydrogen were used as reductants. Tests of the catalysts were performed with various loads, temperatures, and NO _x levels. A light-duty diesel engine with no particulate control was used for the tests. All tests were conducted using No. 2 Diesel fuel. NO _x conversion decay is compared with and without sulfur catalyst protection.
