摘要： A highly porous substrate is provided using an extrusion system. More particularly, the present invention enables the production of a highly porous substrate. Depending on the particular mixture, the present invention enables substrate porosities of about 60% to about 90%, and enables advantages at other porosities, as well. The extrusion system enables the use of a wide variety of fibers and additives, and is adaptable to a wide variety of operating environments and applications. Fibers, which have an aspect ratio greater than 1, are selected according to substrate requirements, and are typically mixed with binders, pore-formers, extrusion aids, and fluid to form a homogeneous extrudable mass. The homogeneous mass is extruded into a green substrate. The more volatile material is preferentially removed from the green substrate, which allows the fibers to form interconnected networks. As the curing process continues, fiber to fiber bonds are formed to produce a structure having a substantially open pore network. The resulting porous substrate is useful in many applications, for example, as a substrate for a filter or catalyst host, or catalytic converter.

摘要： A Selective Catalytic Reduction (SCR) filter is provided for use in emission control systems, for example, on the exhaust gas from an internal combustion engine. The SCR filter has a substrate constructed using bonded fiber structures, which cooperate to form a highly uniform open cell network, as well as to provide a uniform arrangement of pores. The substrate typically is provided as a wall-flow honeycomb structure, and in one example, is manufactured using an extrusion process. In this way, the substrate has many channel walls, each having an inlet surface and an outlet surface. The inlet surface has a uniform arrangement of pores that form a soot capture zone, where soot and other particulate matter is captured from an exhaust gas. A NOx conversion catalyst is disposed inside the channel wall, where NOx and ammonia in the exhaust gas are reacted to less harmful substances. Because of the uniform pore structure and open cell arrangement inside the channel wall, the filter is capable of being heavily loaded with catalyst, while avoiding undue increase in backpressure to the internal combustion engine.

摘要： A porous ceramic substrate is disclosed that is fabricated from biosoluble ceramic fibers. Porosity and permeability of the substrate is provided by intertangled biosoluble fibers, that can be formed into a honeycomb form substrate through an extrusion process. The fibrous structure is formed from mixing biosoluble fibers with additives that include a bonding agent, and a fluid to provide an extrudable mixture. The structure is sintered at a temperature that exceeds the glass formation temperature of the bonding agent, but less than the maximum operational limits of the biosoluble fiber, to form a structure that has sufficient strength and porosity to provide for filtration and/or as a catalytic host.

摘要： A process is provided for strengthening a porous substrate. The process includes providing a substrate having intersecting fibers, where the intersecting fibers cooperate in the final substrate product to form an open pore network. Pathways are opened into the fibrous substrate structure, which enable a flow of gas into the or through the substrate. The substrate is positioned in a CVD (chemical vapor deposition) station, and one or more layers of a strengthening agent is deposited. The deposited layer or layers form a strong coating around fibers and fiber intersections to provide additional strength to the substrate. The strengthened substrate may then be used in wide variety of applications and fields. Advantageously, the disclosed fiber strengthening process produces a substrate having high porosity and higher strength characteristics as compared to a non-strengthened substrate.
