  • Iron-promoted zeolite and catalyst made therefrom
    Patent number: 11931729
    Abstract: The present disclosure provides a method of forming a selective catalytic reduction (SCR) catalyst, the method including receiving a first iron-promoted zeolite having a first iron content, and treating the iron-promoted zeolite with additional iron in an ion exchange step to form a second iron-promoted zeolite with a second iron content, the second iron content being higher than the first iron content. A selective catalytic reduction (SCR) catalyst composition including an ironpromoted zeolite having at least about 6 weight percent iron, based on total weight of the ironpromoted zeolite, wherein the iron content of the zeolite was added to the zeolite in at least two separate steps is also provided herein.
    Type: Grant
