摘要:
Zeolite-based honeycomb bodies and methods of manufacturing same. Zeolite-based honeycomb bodies especially suited for engine exhaust treatment applications include a primary phase comprising a zeolite having a SiO2 to Al2O3 molar ratio in the range from 5 to 300. The zeolite-based composites are porous with an open porosity of at least 25% and a median pore diameter of at least 1 micron. The zeolite-based honeycomb bodies can be manufactured by an extrusion method.

摘要:
A filter apparatus comprises a filter stack including a plurality of porous ceramic plates that are axially spaced from one another to define plurality of axially spaced apart radial flow areas. In one example, the filter stack is mounted within a housing. In further examples, the plurality of porous ceramic plates alternate between a first set of porous ceramic plates that are nested with a second set of porous ceramic plates. In still further examples, at least one of the sides of the porous ceramic plates defines a plurality of radial flutes arranged in a radial array.
摘要:
A ceramic forming batch mixture including inorganic batch materials, such as sources of alumina, titania, and silica, a pore former combination including first and second pore formers with different compositions; an organic binder; and a solvent. Also disclosed is a method for producing a ceramic article involving mixing the inorganic batch materials with the pore former combination having first and second pore formers of different composition, adding an organic binder and a solvent, forming a green body; and firing the green body. A green body having a combination of first and second pore formers with different compositions is disclosed, as are several methods for firing to produce ceramic articles such as aluminum titanate.
摘要:
Methods of making a filter apparatus includes the step of creating a filter stack by axially spacing the porous ceramic plates from one another with a plurality of compliant spacers. In another example, the method includes the step of firing the first filter stack to sinter bond the first plurality of porous ceramic plates together with a first spacing element. In another example, the plurality of plates comprise a composition including catalyst particles and a binder material and the plates are fired to form porous plates without sintering a substantial amount of the catalyst particles. Methods of fabricating a porous ceramic article also include providing a porous substrate with a first material composition including mullite and infiltrating the pores of the substrate with a second material composition including cordierite. The method further includes the step of firing the first composition and the second composition to form the porous ceramic article.
