A method of adhering a particulate material, such as a hydrocarbon adsorbent material and/or a catalytic material, to a plastic surface, and products comprising the adhered material are disclosed.

Polymeric trap with adsorbent

The invention provides a catalyzed soot filter formed on a wall flow substrate having internal walls coated with catalyst compositions. The soot filter maintains a homogeneous flow of the exhaust gases through the internal walls of the substrate along the length of the filter due to the coating design. Both the efficiency and the durability of the catalytic function are increased over conventionally designed catalyzed soot filters. The catalyzed soot filter provides an integrated function for simultaneously treating the gaseous components of the exhaust (e.g., CO and HC) and the particulate matter deposited in the filter.

Pressure-balanced, catalyzed soot filter

The present invention is directed to the use of an improved hydrocarbon adsorbent coating for the treatment of evaporative emissions from a motor vehicle. More specifically, one or more hydrocarbon adsorbents, in accordance with the present invention, can be coated to any surface area of an air intake system to trap hydrocarbon vapors before they can escape to the atmosphere, through said air intake system. In another embodiment, one or more hydrocarbon adsorbents can be incorporated in the air filter of an air intake system.

Provided is an exhaust article (catalyst) coated on a single substrate, such as a monolithic honeycomb having a plurality of channels along the axial length of the catalyst. Different washcoat compositions are deposited along the length the channel walls of the substrate beginning from either the inlet or outlet axial end of the substrate to form inlet and outlet catalyst layers, respectively. In the coating process, the channel walls are coated with catalyst washcoat compositions to lengths that are less than the substrates' axial length. The architecture of the resulting catalyst layers defines a plurality of zones along the length of the substrate. The properties of each zone of the catalyst can be optimized to address specific catalyst functions by manipulation of both the coating lengths and the catalyst washcoat compositions.

Multi-zone catalytic converter

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

The present invention relates to a layered catalyst composite of the type generally referred to as a three-way conversion catalyst having the capability of simultaneously catalyzing the oxidation of hydrocarbons and carbon monoxide and the reduction of nitrogen oxides. The structure of the layered catalyst composite of the present invention is designed wherein there are three layers in conjunction with a carrier: a first layer deposited on the carrier and comprising a high surface area refractory metal oxide; a second layer deposited on the first layer and comprising palladium and/or platinum deposited on a high surface area refractory metal oxide, and having substantially no oxygen storage components; and a third layer deposited on the second layer and comprising platinum and/or rhodium as well as an oxygen storage component, deposited on a high surface area refractory metal oxide.

Catalytic material for treating pollutant-containing gases

A pollutant treating device especially adapted for motor vehicles in which a housing containing a catalyst composition for treating pollutants is positioned within the normal flow pattern of ambient air within the motor vehicle and is preferably removably placed within a support, such as a bracket assembly where the housing can be readily removed and replaced and/or reused.

A pre-vaporized fuel system for use in fueling an internal combustion engine is provided with a dynamic infrared sensor. The infrared sensor senses the hydrocarbon content of the vaporized fuel which information is used by the engine control module to control engine fueling to minimize emissions. The infrared source is operated to maintain the pre-vaporized fuel below its lower explosive limit and the thermopile detector electronics is synchronized with the light pulse frequency to develop fast signal responses suitable for fueling control.

Method and apparatus for treating the atmosphere to lower the concentration of pollutants therein in which ambient air is passed into operative contact with a stationary substrate having at least one ambient air contacting surface having a pollutant treating material thereon.

Method and apparatus for treating the atmosphere

A rotary regenerative catalytic oxidizer is disclosed which is a portable, compact system that catalytically destroys VOC and odorous compounds at elevated temperatures of 400 to 800&deg; F. Equipped with a very high thermally efficient rotor of 90&plus;%, most heat for reaction is retained in the apparatus, and the cleaned air at temperatures of 80 to 120 F. is safely discharged into room without causing discomfort. As a portable unit, it can be conveniently used to treat local areas where odorous and/or hazardous VOC and CO compounds are present and conveniently run off household 120V or 220V systems.

Portable rotary catalytic oxidizer systems

A method and apparatus in accordance with the invention is described which comprises treating an engine exhaust gas stream containing hydrocarbons and other pollutants. The method of this invention comprises the steps of flowing the exhaust gas stream through a catalytic member comprising a monolith body having a first catalyst zone and a second catalyst zone therein to contact a catalyst in a first catalyst zone to convert at least some of the pollutants in the exhaust gas stream into innocuous products. The exhaust gas stream is then discharged from the catalytic member and flowed through an adsorbent zone to adsorb at least some of the hydrocarbon pollutants with an adsorbent composition. The exhaust gas stream is then discharged from the adsorbent zone and flowed to the second catalyst zone to convert at least some of the pollutants into innocuous products. The exhaust gas stream, so treated, is then discharged to the atmosphere through suitable discharge means. A preferred adsorbent is a zeolite, having a relatively high silica to alumina ratio and a low relative Bronsted acidity. The preferred adsorbent compositions comprise Beta zeolites. An oxidant such as air may be added to the exhaust gas stream at a point upstream of the second catalyst zone.
