Evaporative emission device and adsorbent

Disclosed herein are catalyst compositions for removing formaldehyde, volatile organic compounds, and other pollutants from an air flow stream. In one embodiment, a catalyst composition comprises manganese oxide particles and rare earth metal catalyst particles.

Catalyst device for treatment of formaldehyde and volatile organic compounds

The present disclosure relates to hydrocarbon emission control systems. More specifically, the present disclosure relates to substrates coated with hydrocarbon adsorptive coating compositions and evaporative emission control systems for controlling evaporative emissions of hydrocarbons from motor vehicle engines and fuel systems. The hydrocarbon adsorptive coating compositions include particulate carbon having a BET surface area of at least about 1300 m/g, and at least one of (i) a butane affinity of greater than 60% at 5% butane; (ii) a butane affinity of greater than 35% at 0.5% butane; (iii) a micropore volume greater than about 0.2 ml/g and a mesopore volume greater than about 0.5 ml/g.

Evaporative emission control articles including activated carbon

The present disclosure relates to hydrocarbon emission control systems. More specifically, the present disclosure relates to substrates coated with hydrocarbon adsorptive coating compositions and evaporative emission control systems for controlling evaporative emissions of hydrocarbons from motor vehicle engines and fuel systems. The hydrocarbon adsorptive coating compositions include particulate carbon having a BET surface area of at least about 1300 m/g, and at least one of (i) a butane affinity of greater than 60% at 5% butane; (ii) a butane affinity of greater than 35% at 0.5% butane; (iii) a micropore volume greater than about 0.2 mug and a mesopore volume greater than about 0.5 ml/g.

Disclosed herein are a catalyst composition, catalyst devices, and methods for removing formaldehyde, volatile organic compounds, and other pollutants from an air flow stream. The catalyst composition including manganese oxide, optionally one or more of alkali metals, alkaline earth metals, zinc, iron, binder, an inorganic oxide, or carbon.

Manganese oxide based catalyst and catalyst device for the removal of formaldehyde and volatile organic compounds

A coated substrate () adapted for hydrocarbon adsorption having at least one surface, and a coating on the at least one surface, the coating comprising particulate carbon and a binder, wherein the particulate carbon has a BET surface area of at least about 1300 m/g; and at least one of: (i) a butane affinity of greater than 60% at 5% butane; (ii) a butane affinity of greater than 35% at 0.5% butane; (iii) a micropore volume greater than about 0.2 ml/g and a mesopore volume greater than about 0.5 ml/g. A bleed emission scrubber () and an evaporative emission control canister system () comprising the coated substrate () are provided. They can control evaporative hydrocarbon emissions and may provide low diurnal breathing loss (DBL) emissions even under a low purge condition.

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.

Carbon dioxide sorbents for air quality control

Disclosed herein are catalyst devices for removing formaldehyde, volatile organic compounds, and other pollutants from an air flow stream, A catalyst device includes a housing, a solid substrate disposed within the housing, and a catalyst layer disposed on the substrate. The catalyst layer includes a base metal catalyst at a first mass percent and a rare earth metal catalyst at a second mass percent.

Provided are methods of making dehydrogenation catalyst supports containing bayerite and silica. Silica-stabilized alumina powder, prepared by spray drying of bayerite powder, precipitating silica in a bayerite slurry with an acid, or impregnation or co-extrusion of bayerite with sodium silicate solution was found to be a superior catalyst support precursor. Catalysts prepared with these silica containing support materials have higher hydrothermal stability than current CATOFIN&#xae; catalysts. Also provided is a dehydrogenation catalyst comprising CrO, an alkali metal oxide, SiOand AlO, and methods of using said catalyst to make an olefin and/or dehydrogenate a dehydrogenatable hydrocarbon.

Chromia alumina catalysts for alkane dehydrogenation

A process for the production of propylene, the process including: contacting ethylene and a hydrocarbon stream comprising 1-butene and 2-butene with a bifunctional isomerization-metathesis catalyst to concurrently isomerizes 1-butene to 2-butene and to form a metathesis product comprising propylene; wherein the bifunctional isomerization-metathesis catalyst comprises: a catalyst compound may include at least one element selected from tungsten, tantalum, niobium, molybdenum, nickel, palladium, osmium, iridium, rhodium, vanadium, ruthenium, and rhenium for providing metathesis activity on a support comprising at least one element from Group IA, IIA, IIB, and IIIA of the Periodic Table of the Elements; wherein an exposed surface area of the support provides both isomerization activity for the isomerization of 1-butene to 2-butene; and reactive sites for the adsorption of catalyst compound poisons. In other embodiments, the catalyst compound may include at least one element selected from aluminum, gallium, iridium, iron, molybdenum, nickel, niobium, osmium, palladium, phosphorus, rhenium, rhodium, ruthenium, tantalum, titanium, tungsten, and vanadium.
