Method of fabricau00c7u00e7o activated carbon modified

摘要

b method of fabricau00c7u00e7o activated carbon modified d , the present invention relates to a modified activated carbon and a manufacturing process of a modified activated carbon from a substrate of activated carbon.The substrate of activated carbon is pre treated to produce an exposed surface of the substrate substantially hydrophilic activated carbon, coated with a carbon precursor to form a coated activated carbon, and then the coated substrate is heated decarbono activated The, to burn the carbon precursor to form the active carbon modified.The modified activated carbon comprises a uniform porous carbon membrane formed on an exposed surface of the substrate of activated carbon.The carbon membrane can mediate the absorption kinetics and / or adsoru00e7u00e1o substrate of activated carbon, activated carbon was modified, which can be incorpo - erate in one or more components of a cigarette, can selectively remove the gaseous constituents of the smoke as usual during the act D And smoking.
