Abstract: Carbon dioxide and VOC sorbents that include a porous support impregnated with an amine compound are provided. The sorbents include a gas-adsorbing material coated onto the porous support. The gas-adsorbing material includes a polyamine which is produced using a process that is free of formaldehyde as a reaction product and/or a reactant.

Abstract: Disclosed in certain embodiments are carbon dioxide and VOC sorbents that include a porous support impregnated with an amine compound.

Abstract: Methods of applying a sorbent coating on a substrate, a support, and/or a substrate coated with a support are described. One of the methods comprises: (i) optionally, preparing the substrate coated with the support by pre-treating the substrate with a slurry, wherein the slurry comprises: a. solvent, b. a binder, c. the support, and d. optional dispersant; and (ii) treating the substrate, the support, and/or the substrate coated with the support, with a sorbent.

Abstract: Air treatment catalyst systems and methods for treating the air in the aircraft cabin environment are provided. The catalyst system and method remove ozone, volatile organic compounds, NOx and other pollutants. The catalyst system used to treat the cabin air comprises a plurality of discrete substrates having an ozone abatement catalyst loaded thereon and arranged in a stacked configuration between a source of the air stream and the passenger cabin, the at least the first two substrates adjacent the source of the air stream comprise an iron-based alloy.

Abstract: Air treatment systems including an environmental control system, a mixer, an air distribution duct system, and one or more catalysts for treating the air in the aircraft cabin environment are provided. Methods for treating aircraft cabin air are also provided. The air treatment systems treats compressed air provided to the aircraft cabin, which can include bleed air and bleedless air, and also treats existing air recirculated from an aircraft cabin to remove ozone, volatile organic compounds, NOx and other pollutants. The catalysts used to treat the compressed air, recirculated air and/or combined compressed and recirculated air are disposed at various stages of the air treatment systems described herein.

Abstract: The present invention is directed to an evaporative emissions control apparatus for minimizing fuel vapor emissions from a fuel storage system in a vehicle with an internal combustion engine. More specifically, the present invention is directed to an evaporative emissions control apparatus comprising a canister filled with a hydrocarbon adsorbent. The present invention is also directed an evaporative emissions control apparatus comprising a support substrate, which is coated with a hydrocarbon adsorbent slurry.

Abstract: The present invention is directed to the use of an improved hydrocarbon adsorbent coating for the treatment of exhaust emissions from a motor vehicle. More specifically, the hydrocarbon adsorbent of the present invention can be coated to any surface area of an exhaust gas recirculation system to trap hydrocarbon vapors before they can be released to the atmosphere.

Abstract: The present invention is directed to an improved hydrocarbon adsorbent slurry washcoat formulation, which can be used for controlling evaporative hydrocarbon emissions from a motor vehicle. More specifically, the present invention is directed to an improved slurry composition of the present invention comprises one or more hydrocarbon adsorbent materials, and an organic polymer binder containing an anionic dispersant and/or stabilizing pH. The binder is used to improve the adhesion of the hydrocarbon adsorbent to the surface of the fuel storage, fuel delivery, or air intake system component.

Abstract: 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.

Abstract: A hydrocarbon adsorption unit for recovery of volatile hydrocarbons which emanate from several sources and which would otherwise be released into the atmosphere through the air cleaner of an automobile engine when the engine is shut off. The unit is positioned in the air intake system such that all air flowing through the engine passes through the unit. The unit comprises a housing having an air inlet and an air outlet. The housing contains a substrate and a volatile hydrocarbon adsorber material coated on the surface of the substrate. The adsorber material may be silica gel, a molecular sieve and/or activated carbon. The material further contains a binder that will cause the material to adhere to the surface of the substrate.
