A method for manufacturing an adsorption agent for treating compressed gas, which includes the steps of providing a monolithic supporting structure; producing a coating suspension that includes an adsorbent; applying the coating suspension on the supporting structure to form a coating; applying a thermal treatment to the coated supporting structure in order to sinter the coating.
METHOD OF PRODUCING POROUS BODY
Provided is a method of producing a porous body of a water-insoluble polymer, the method being excellent in terms of simplicity and capable of suppressing formation of a skin layer. A method of producing a porous body of a water-insoluble polymer disclosed here includes the steps of: preparing a solution in which a water-insoluble polymer is dissolved in a mixed solvent containing a good solvent for the water-insoluble polymer and a poor solvent for the water-insoluble polymer; coating the solution on a substrate; coating a slurry containing insulating particles, a binder and a dispersion medium on the coated solution; and simultaneously drying the coated solution and the slurry to porosify the water-insoluble polymer. The poor solvent has a boiling point higher than a boiling point of the good solvent. The dispersion medium can dissolve the water-insoluble polymer.
EVAPORATIVE EMISSION DEVICE AND ADSORBENT
The present disclosure relates to hydrocarbon emission control systems. More specifically, the present disclosure relates to substrates coated with hydrocarbon adsorptive coating compositions, air intake systems, and evaporative emission control systems for controlling evaporative emissions of hydrocarbons from motor vehicle engines and fuel systems.
METHODS WITH A CONSTRUCTION THAT ABSORBS AN ORGANIC CHEMICAL
Construction for absorbing a fluid, for example, a liquid or gaseous, organic chemical, has an extended web, fabric, yarn or foam member and associated with the extended web, fabric, yarn or foam member is a water-insoluble polymer. The water-insoluble polymer can absorb the fluid organic chemical, and the construction provides for contact of the water-insoluble polymer with the fluid organic chemical when deployed in an environment where the fluid organic chemical may be present for absorption. The construction may be employed in aquatic, aqueous, or dry environments, as a blotter, a wipe or sponge, a filter, in a cartridge, and so forth.
