Abstract:
A method for applying a surface treatment to a plugged honeycomb body comprising porous wall includes: mixing particles of an inorganic material with a liquid vehicle and a binder material to form a liquid-particulate-binder stream; mixing the liquid-particulate-binder stream with an atomizing gas, directing the liquid-particulate-binder stream into an atomizing nozzle thereby atomizing the particles into liquid-particulate-binder droplets comprised of the liquid vehicle, the binder material, and the particles; conveying the droplets toward the plugged honeycomb body by a gaseous carrier stream, wherein the gaseous carrier stream comprises a carrier gas and the atomizing gas; evaporating substantially all of the liquid vehicle from the droplets to form agglomerates comprised of the particles and the binder material; depositing the agglomerates onto the porous walls of the plugged honeycomb body; wherein the deposited agglomerates are disposed on, or in, or both on and in, the porous walls.
Abstract:
Filtration articles herein exhibit excellent filtration efficiency and pressure drop before and after water durability testing. The articles comprise: a honeycomb filter body; inorganic deposits disposed within the honeycomb filter body at a loading of less than or equal to 20 grams of the inorganic deposits per liter of the honeycomb filter body. The inorganic deposits are comprised of refractory inorganic nanoparticles bound by a high temperature binder comprising one or more inorganic components. At least a portion of the inorganic deposits form a porous inorganic network over portions of inlet walls of the honeycomb filter body.
Abstract:
A cement composition for plugging a honeycomb body, a plugged honeycomb body, and methods of plugging a honeycomb body are provided. The cement composition includes a source of inorganic particles, an inorganic binder, an organic binder, and a crosslinking agent that is capable of reacting with the inorganic binder and the organic binder. The cement composition can be dried without firing to form water-resistant plugs in a honeycomb body.
Abstract:
A particulate filter having a porous ceramic honeycomb structure with a first end, a second end, and a plurality of walls having wall surfaces defining a plurality of inner channels. Filtration material deposits are disposed on one or more of the wall surfaces of the honeycomb body. The highly porous deposits provide durable high clean filtration efficiency with small impact on pressure drop through the filter.
