The present disclosure provides binder compositions formed with a plurality of binder materials having differing mean particles, the binder compositions being useful to improve washcoat adhesion on a substrate. Adhesion can be improved related to an increase in the binder concentration without a significant or substantial increase in associated viscosity. Such binder compositions can comprise a first binder material formed of a plurality of particles having a first mean particle size and a second binder material formed of a plurality of particles having a second mean particle size, wherein a ratio of the first mean particle size to the second mean particle size about 2 or greater. The present disclosure further provides catalyst compositions, catalyst articles, and emission systems incorporating the binder compositions.

Binder composition for enhanced catalyst washcoat adhesion

Catalyzed particulate filters comprise three-way conversion (TWC) catalytic material that permeates walls of a particulate filter such that the catalyzed particulate filter has a coated porosity that is less than an uncoated porosity of the particulate filter. The coated porosity is linearly proportional to a washcoat loading of the TWC catalytic material. A coated backpressure is non-detrimental to performance of the engine. Such catalyzed particulate filters may be used in an emission treatment system downstream of a gasoline direct injection engine for treatment of an exhaust stream comprising hydrocarbons, carbon monoxide, nitrogen oxides, and particulates.

Four way conversion catalysts for gasoline engine emissions treatment systems

The present invention relates to a catalyst for the conversion of oxygenates to olefins, comprising

Catalyst coating and process for the conversion of oxygenates to olefins

Provided are catalyst composites whose catalytic material is effective to substantially simultaneously oxidize carbon monoxide and hydrocarbons and reduce nitrogen oxides. The catalyst composites have a two-metal layer on a carrier, the two-metal layer comprising a rhodium component supported by a first support comprising a refractory metal oxide component or a first ceria-zirconia composite; a palladium component supported by a second support comprising a second ceria-zirconia composite; one or more of a promoter, stabilizer, or binder; wherein the amount of the total of the first and second ceria-zirconia composites in the two-metal layer is equal to or greater than the amount of the refractory metal oxide component. Methods of making and using the same are also provided.

Automotive catalyst composites having a two-metal layer

The invention relates to a catalyst comprising a monolith composed of a catalytically inert material with low BET surface area and a catalyst layer which has been applied to the monolith and comprises, on an oxidic support material, at least one noble metal selected from the group consisting of the noble metals of group VIII of the Periodic Table of the Elements, optionally tin and/or rhenium, and optionally further metals, wherein the thickness of the catalyst layer is 5 to 500 micrometers.
