摘要： A catalytic wall-flow monolith filter for use in an emission treatment system comprises a wall flow substrate having a first face, a second face, and first and second 5 pluralities of channels, wherein the first plurality of channels is open at the first face and closed at the second face, and the second plurality of channels is open at the second face and closed at the first face. The monolith filter comprises a porous substrate having a first zone extending from the first face towards the second face and a second zone extending from the second face towards the first face, where each of the zones are less that filter length. A first 0 catalytic material is distributed throughout the first zone of the porous substrate, and a second catalytic material covers at least a portion of the surfaces in the second zone of the porous substrate and is not distributed throughout the porous substrate.

摘要： The disclosure relates to a method of forming a coated monolith article for the treatment of an exhaust gas. The method comprises the steps of: retaining a porous monolith article in a coating apparatus, the porous monolith article comprising a plurality of channels for the passage of an exhaust gas, each channel having a gas-contacting surface; depositing cementitious particles as a dry powder onto the gas-contacting surface of at least some of the channels; and reacting the cementitious particles with a liquid or gaseous reagent in situ within the porous monolith article to provide the coated monolith article.

摘要： The present invention is directed to a method of preparing a synthetic crystalline material, designated as JMZ-12, with a framework built up by the disorder AEI and CHA structures, substantially free of framework phosphorous and prepared preferably in the absence of halides such as fluoride ions. Such method comprises the step of heating a reaction mixture under crystallization conditions for a sufficient period to form a disordered zeolite having both CHA and AEI topologies, wherein the reaction mixture comprises at least one source of aluminum, at least one source of silicon, a source of alkaline or alkaline-earth cations, and a structure directing agent containing at least one source of quaternary ammonium cations and at least one source of alkyl-substituted piperidinium cations in a molar ratio of 0.20 to about 1.4. The resulting zeolites are useful as catalysts, particularly when used in combination with exchanged transition metal(s) and, optionally, rare earth metal(s).

摘要： Provided is a catalyst washcoat comprising (i) a molecular sieve loaded with about 1 to about 10 weight percent of at least non-aluminum promoter metal (wherein the promoter metal weight percent is based on the weight of the molecular sieve); and (ii) about 1 to about 30 weight percent of a binder having a d90 particle size of less than 10 microns (wherein the binder weight percent is based on the total weight of the washcoat). In another aspect of the invention, the catalyst washcoat is applied to a wall-flow filter to form a catalyst article. In another aspect of the invention the catalyst article is part of an exhaust gas treatment system. And in yet another aspect of the invention, provided is a method for treating exhaust gas using the catalyst article.

摘要： The invention relates to a catalyst article for the treatment of an exhaust gas, the catalyst article comprising a wall-flow filter comprising at least first, second and third catalytic layers. The first catalytic layer extends from the inlet-end of the substrate and comprises a first SCR composition. The second catalytic layer is provided in or on the walls of the inlet channels, extending from the inlet-end of the substrate, and comprises a PGM-containing composition. The third catalytic layer is provided in or on the walls of the outlet channels, extending from the outlet-end of the substrate, and comprises a second SCR composition. A ratio of the PGMs in the second catalytic layer in g per ft3 to the total amount of the first and second SCR compositions in the first and third catalytic layers in g per in3 is from 1.5:8 to 5:8.
