    摘要： A manufacturing process for producing a particulate reactor substrate according to the invention includes the steps of first roll-stamping small, raised dimples into the fabric substrate to control its coiled density. The dimpled fabric then undergoes high temperature firing for hardening and degreasing, and then water quenching to harden the metal which improves heat tolerance. The treated metal weave is then aluminum oxide shot-blasted to etch the fabric surface for improved ceramic coating adhesion and to increase surface area. Next, the fabric is coated with a wet slurry of an undercoating (“wash coat”) prior to spooling and pressing the fabric into individualized cartridges that are held tightly wound by an encircling sleeve. Next, the sleeved spools are oven-fired and then the fired spools are impregnated with the catalytic precious metal. The impregnated sheathed spools are finally oven-fired again and “canned” into an outer enclosure.

    摘要： The invention relates to a process for the production of a catalyzer and a catalyzer for the removal of polluting components from exhaust gases of internal combustion engines, particularly Otto-engines, by using carrier materials provided with catalytically effective metallic compounds. The catalyzer is not only simple and cost-effective to produce but also is very efficient at removing polluting components from exhaust gases, can be operated with leaded gasoline and has a comparatively long life components of the catalyzer include approx. 22-26% by weight of cobalt oxide, approx. 8-15% by weight manganous oxide, approx. 4-6% by weight copper oxide, approx. 25-35% by weight clay, and approx. 27-35% by weight talc. All these components are first premixed together in a dry powder form, homogenized and brought to the desired final particle size. Subsequently the powder mixture to be plastified is agitaled in a mixer and granulated through a sieve resultant granulate is then pressed into molds to be dried at approx. 50-150 degrees C and then burned at a temperature of approx. 850-900 degrees C.

    摘要： A method for rigidifying a fiber-based paper substrate for use in the exhaust system of a combustion device. In the method, a green ceramic fiber-based paper substrate is impregnated with an impregnating dispersion. The impregnated substrate is then dried, calcined and fired to form a rigidified substrate that is suitable for use in the exhaust system of a combustion device. This rigidification process is performed at least once and, preferably, two or more times. The green paper substrate comprises two or more sheets of green ceramic fiber-based paper, with at least one creased sheet and another sheet being a laminated together to form a plurality of tubular channels. The rigidified substrate comprises refractory ceramic fibers in the form of a ceramic fiber-based paper and agglomerates of ceramic particles. The ceramic particle agglomerates are bonded to and disposed so as to thereby bond together the refractory ceramic fibers at spaced locations along and at intersections of the refractory ceramic fibers so that the refractory ceramic fibers retain much of their original flexibility while in the paper.
