  • Zoned catalyst for treating exhaust gas
    Patent number: 9597636
    Abstract: 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.
    Type: Grant

  • Zoned catalyst for treating exhaust gas
    Patent number: 9579603
    Abstract: Provided is a system for treating an exhaust gas comprising a first SCR catalyst zone comprising vanadium loaded on a metal oxide selected from TiO2, ZrO2, SiO2, CeO2, and Al2O3; and a second SCR catalyst zone comprising a copper loaded small-pore molecular sieve, 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. Also provided is a method for using the system to treat exhaust gas.

  • Catalytic article for treating exhaust gas
    Patent number: 9545602
    Abstract: Provided is a catalytic article comprising (a) a flow through honeycomb substrate having channel walls; (b) a first NH3-SCR catalyst composition coated on and/or within the channel walls in a first zone; and (c) a second NH3-SCR catalyst composition coated on and/or within the channel walls in a second zone, provided that the first zone is upstream of the second zone and the first and second zones are adjacent or at least partially overlap; and wherein the first NH3-SCR catalyst comprises a first copper loaded molecular sieve having a copper to aluminum atomic ratio of about 0.1 to 0.375 and the second NH3-SCR catalyst comprises a second copper loaded molecular sieve having a copper-to-aluminum atomic ratio of about 0.3 to about 0.6.
