Abstract: An apparatus, system and method are disclosed for modifying a gaseous mixture. The apparatus comprises a unitary body (10) having an inlet end (18), an outlet end (20), and a multiplicity of cells extending from inlet end to outlet end, the cells being separated from one another by porous walls, and filler material comprising electrically non-conducting active powder material, loaded into at least part of the volume of the cells (14), with some of the cells being unloaded and open (16), wherein a gaseous mixture enters the body at the inlet end through the open cells, and at least some of the gaseous mixture passes through the porous walls and is compositionally modified by the active material, and thereafter the resultant modified mixture passes through the open cells and exits the body at the outlet end. The apparatus can be used in conjunction with other apparatuses which are catalyzed to form a gas modifying system. The apparatus and system are especially suited for conversion of hydrocarbons, NOx, and CO as from auto exhaust, and for Denox applications.

Abstract: The present invention features a process, and a product formed by the process, wherein a catalyst device is fabricated in situ. Metal powders, metal alloy powders and mixtures thereof are introduced to a substrate, by means of a washcoat suspension. After the suspension is applied, the metals are transformed into active catalyst and catalyst support materials. The process comprises the steps of: (a) introducing to a substrate, metal powders, metal alloy powders and mixtures thereof, having particles in average diameter sizes of approximately between 5 and 50 microns; and (b) transforming in situ the particles of the metals and metal alloys and mixtures thereof, whereby the metals, metal alloys and mixtures thereof are converted into active catalyst and catalyst support materials having sub-micron average diameter sizes.
