A method and apparatus for treating the atmosphere comprising moving a vehicle through the atmosphere, the vehicle having at least one atmosphere contacting surface and a pollutant treating composition located on said surface. A specific embodiment comprises coating a motor vehicle radiator with pollutant treating catalyst.

Vehicle having atmosphere pollutant treating surface

A vehicular atmosphere cleansing system utilizes a regenerative wheel having flow channels extending through the wheel coated with an adsorbant. An atmosphere stream passes through a first position dependent portion of the wheel where VOC's including HC's are adsorbed while a heated atmosphere stream passes through a second position dependent regenerative portion of the wheel whereat VOC's are desorbed. The adsorbant is activated carbon having particles of micropore size adhered to the substrate by a silicone binder producing high adsorption efficiencies while withstanding relatively high regenerative heat temperatures resulting from exhaust gas sensible heat. A hydrocarbon senses HC in the desorbed heated atmosphere stream to rotatively and sequentially index pie shaped, segmented portions of the wheel into the wheel's regenerative region while also functioning as the main component of an OBD device for the system.

Vehicular atmosphere cleansing method

A catalytic composition and method of making the same in which a catalytic material has an average pore size distribution sufficiently large to substantially prevent capillary condensation.

Hydrophobic catalytic materials and method of forming the same

A composition and method for improving the adhesion properties of catalytic and adsorptive compositions to a substrate through the addition of clay and/or silicone binder is disclosed. Preferably, the composition includes manganese dioxide and attapulgite clay and/or a silicone polymer which is adhered to a metal substrate, such as a motor vehicle radiator.

Catalyst and adsorption compositions having improved adhesion characteristics

Stable slurries of catalytically active materials

Catalytic material for treating pollutant-containing gases

Method for treating atmospheric pollutants by contacting the atmosphere with a catalyst composition or adsorptive material coated on the surface of a substrate, preferably a motor vehicle radiator, in which the catalyst composition, preferably including a base metal, precious metal, or salts/oxides thereof, or adsorptive material, preferably including a zeolite, Group IIA alkaline earth metal oxide or carbon, is protected from degradation by harmful contaminants such as solid or aerosol particulates, water, SOx, NOx and water borne salts contained in the atmosphere by a coating of at least one porous protective material and a device useful therefor.

Method and device for cleaning the atmosphere

Method for cleaning the atmosphere by adsorbing pollutants, e.g., hydrocarbons, ozone, carbon monoxide, nitrogen oxides, sulfur oxides, etc., contained in the atmosphere. The pollutant-containing atmosphere is contacted with an outer surface of a substrate, e.g., radiators, condensers, charge air coolers, transmission coolers, etc., which has been coated with an adsorptive material such as zeolites, molecular sieves, carbon, etc. The coated substrate is protected with an overcoat of at least one porous protective material such as alumina, silica and the like, such that the pollutants will come into contact with the adsorptive material, but harmful contaminants will be prevented from contacting the adsorptive material.

Catalyst and adsorption compositions having adhesion characteristics

An OBD system is provided for monitoring an ozone depletion system that includes a catalyst coating containing MnO applied to a heat exchange surface on a moving vehicle over which atmospheric air passes. A physical characteristic of the catalyst coating or a material containing a physical characteristic within the catalyst coating is sensed to determine the presence or absence of the catalyst coating for detecting catastrophic failure of the ozone depleting system and/or degradation or wear of the catalyst coating to ascertain the efficiency of the catalyst coating.

System for sensing catalyst coating loss and efficiency

An exhaust gas treatment apparatus and method for its use includes an upstream catalyst and a downstream catalyst. The upstream catalyst contains a catalytic metal effective at least for the oxidation of hydrocarbons in the exhaust gas stream, and preferably contains a palladium catalytic component and contains substantially no oxygen storage components, i.e., oxides of cerium, cobalt, iron, magnesium, molybdenum, nickel, praseodymium, tungsten and vanadium, but the downstream catalyst includes an oxygen storage component. Preferably, the upstream catalyst is a close-coupled catalyst. The downstream catalyst may be an underfloor catalyst or a close-coupled catalyst, in which case there is, preferably, an additional, underfloor catalyst.

Engine exhaust treatment apparatus and method of use

A metal substrate is fabricated and coated with a catalyst for ozone conversion of atmosphere passing through the substrate. A plurality of aluminum foil sheets that have been slit, stretched and twisted into a plurality of regularly repeating channels having geometrically shaped openings are serially positioned one on top the other to form a foil stack with channel openings partially blocked by channel walls of overlying foil sheets. Thicker covers with openings at the top and bottom of the stack form a sandwich and the sandwich pleated to form corrugations in a flexible but rigid sandwich substrate. The channel walls are coated with an ozone depleting catalyst which the ozone atmosphere contacts to remove ozone as the ozone atmosphere travels through the stack construction.

Corrugated metal substrate and coated product for ozone conversion

A composition for abatement of airborne pollution by volatile organic compounds (&ldquo;VOCs&rdquo;) has an upstream composition which contains a protective adsorbent, e.g., Y zeolite, which is effective for adsorbing large VOC molecules, e.g., toluene, and a protective oxidation catalyst intimately intermingled therewith. The downstream composition contains a second adsorbent, e.g., a silver-containing ZSM-5, which is effective for adsorbing relatively smaller VOC molecules, e.g., propylene, and a second oxidation catalyst intimately intermingled therewith. Oxidation of VOCs while they are still retained on the adsorbents is promoted at temperatures lower than would be required if the VOCs were desorbed into the gaseous phase. Apparatus is provided including a first contact member (,) coated with the upstream composition and positioned upstream of a second contact member (,) coated with the downstream composition. A heat exchanger (,) equipped with a temperature control device (,) is positioned upstream of both contact members to vary the treatment temperature between an adsorption temperature range and a higher, oxidation temperature range, both lying within an operating temperature range of from about 20 to 500&deg; C.

Compositions for abatement of volatile organic compounds and apparatus and methods using the same

A stable, close-coupled catalyst, an article comprising the close-coupled catalyst and a related method of operation. The close-coupled catalyst comprises a catalyst support and a palladium catalytic component. Preferably and optionally, there are stabilizers including alkaline metal oxide, and rare earth metal components selected from the neodymium and lanthanum components. The close-coupled catalyst composition includes substantially no additional oxygen storage component such as praseodymium or cerium compounds. There is preferably a catalyst such as a three-way catalyst downstream of the close-coupled catalyst. The downstream catalyst preferably includes an oxygen storage component such as cerium oxide or praseodymium oxide.
