摘要： Provided is a system for treating an exhaust gas comprising a first SCR catalyst zone comprising an iron loaded medium- or large-pore molecular sieve having a first ammonia storage capacity; and a second SCR catalyst zone comprising a copper loaded small-pore molecular sieve having a second ammonia storage capacity, wherein the first SCR catalyst zone is disposed upstream of the second SCR catalyst zone with respect to normal exhaust gas flow through the system and wherein the second ammonia storage capacity is greater than the first ammonia storage capacity. Also provided is a method for using the system to treat exhaust gas.
