International Classification:

F02M 3302

US Classification:

95146, 95900, 123519

Abstract:

Disclosed is a method for sharply reducing diurnal breathing loss emissions from automotive evaporative emissions control systems by providing multiple layers, or stages, of adsorbents. On the fuel source-side of an emissions control system canister, high working capacity carbons are preferred in a first canister (adsorb) region. In subsequent canister region(s) on the vent-side, the preferred adsorbent should exhibit a flat or flattened adsorption isotherm on a volumetric basis and relatively lower capacity for high concentration vapors as compared with the fuel source-side adsorbent. Multiple approaches are described for attaining the preferred properties for the vent-side canister region. One approach is to use a filler and/or voidages as a volumetric diluent for flattening an adsorption isotherm. Another approach is to employ an adsorbent with the desired adsorption isotherm properties and to process it into an appropriate shape or form without necessarily requiring any special provision for dilution.

Abstract:

A method of making a microporous carbon material which includes providing a precursor selected from the group consisting of crystalline salts of aromatic sulfonates and nonporous polymeric salts. Prior to carbonization, the precursor is treated by ion exchange or other conventional processes to introduce a metal such as iron, nickel and cobalt into the precursor. Heat treatment of such composite precursors in the temperature range of 350. degree. to 850. degree. C. in an inert oxygen free atmosphere for a sufficient time promotes thermally induced hydrogen abstraction and rearrangement of BSUs which result in the formation of a composite, carbonaceous microporous material which contains a metal component, and has a pore size distribution in the range of about 4-15. ANG. A. The structural and storage characteristics of the microporous carbon materials are also disclosed.

Abstract:

A highly microporous adsorbent material is formed as a composite of a natural or synthetic clay or clay-like mineral matrix intercalated with an active carbon. The mineral is prepared and selected to have a selected interlayer spacing between microcrystalline sheets. An organic polymeric precursor is contacted therewith to fill the matrix interstices. Then the precursor is polymerized and carbonized to yield the adsorbent material in which the carbon is intercalated into the mineral matrix. The mineral can be naturally occurring smectite or synthetic hydrotalcite.
