Abstract: A support structure for securing a catalyst structure comprising a multiplicity of longitudinally disposed channels for passage of a flowing gas mixture within a reactor, said support structure being comprised of a monolithic open celled or honeycomb-like structure formed by thin strips or ribs of high temperature resistant metal or ceramic which abuts against one end of the catalyst structure, and extends in a direction perpendicular to the longitudinal axis of the catalyst structure to essentially cover an end face (at either the inlet end or outlet end or both) of the catalyst structure with the support structure being secured on its periphery to the reactor wall. The strips or ribs making up the support structure are bonded together to form a unitary structure having cellular openings at least as large as the catalyst structure channel openings.

Abstract: This invention is a device and a process for controlling the emission of volatile organic components. The invention is useful on gaseous or vapor-containing streams containing a minor amount of organic material, particularly on fairly dilute streams or those containing only a few parts per million of the organic material. The device is useful in adsorbing organics as might be found emanating from paint spray booths, restaurants, print shops, dry cleaners, furniture manufacturers, and bakeries.The device may be two-stage including an adsorber and a catalytic oxidation reactor or may be of such a configuration that the same bed is used both as the adsorber and catalytic oxidation reactor. In the former configuration, a first stage contains an electrically conductive adsorbent bed, potentially comprising an adsorbent placed on a conductive support of fibers, foil, or other structure. The adsorbent removes the organic from the gaseous stream as that stream passes through.

Abstract: This invention is a comparatively high pressure combustion process having a two stages in which a fuel is stepwise combusted using specific catalysts and catalytic structures and, optionally, having a final homogeneous combustion zone. The choice of catalysts and the use of specific structures, including those employing integral heat exchange, results in an overall catalyst structure which is stable due to its comparatively low temperature. The product combustion gas is at a temperature suitable for use in a gas turbine, furnace, boiler, or the like, but has low NO.sub.x content.

Abstract: A method for reducing the amount of carbon monoxide produced in the combustion of carbonaceous fuels. The fuel is coated on at least a portion of its exterior surface with a microporous layer of solid particulate matter which is non-combustible at temperatures in which the carbonaceous fuel combusts. This invention is particularly applicable in the reduction of carbon monoxide in the burning of carbonaceous fuel elements found in currently available "smokeless" cigarettes.

Abstract: A process for improved three-way emissions control comprising the steps of contacting the emissions stream with a first catalyst consisting of rhodium supported on a refractory substrate to effect the selective chemical reduction of nitric oxide to nitrogen, said rhodium being present in an amount of at least about 0.002% by weight of the catalyst, said emissions stream being then contacted with a second catalyst consisting of at least one of the noble metals selected from the group of platinum and palladium, said noble metal being present in a small but effective amount to accomplish the oxidation of the hydrocarbons and carbon monoxide left in said emissions stream, said process being accomplished without the addition of oxygen to said emissions stream.
