    摘要： A cigarette filter for removing gas phase constituents from mainstream cigarette smoke as the smoke is drawn through the filter primarily comprises an activated carbon fiber filter section including a bundle of activated carbon fibers. Particulate adsorbent materials such as granules, beads or course powders may be dispersed amongst the activated carbon fibers to aid in removal of the gas phase constituents. Additionally, the activated carbon fiber filter section may be used in combination with a separate bed or beds of particulate adsorbent material. In one embodiment, the activated carbon fibers are positioned within a helical groove on the outside of a threaded rod within the activated carbon fiber filter section. Relatively smaller amounts of activated carbon fibers produce the same smoke constituent reduction as larger amounts of particulate adsorbent material.

    摘要： An activated carbon-containing sorbent is capable of selectively removing one or more selected gaseous components from a gas. The activated carbon-containing sorbent can be incorporated in a smoking article to remove one or more selected components from mainstream smoke. The activated carbon-containing sorbent can be a composite including one or more molecular sieve materials. Methods of making the activated carbon-containing sorbent, cigarette filters and smoking articles including the activated carbon-containing sorbent, as well as methods for smoking a cigarette comprising the activated carbon-containing sorbent, are provided.

    摘要： Smoking articles, filters, and methods for selectively removing selected components from tobacco smoke are disclosed. The smoking articles and filters include composites composed of a porous alumina and/or aluminosilicate matrix containing particles of activated carbon and zeolite molecular sieve adsorbents distributed throughout the matrix which can selectively remove selected components of tobacco smoke. The composites may be made by admixing the adsorbent mixture and a binder such as aluminum hydroxide or montmorillonite clay, adding an aqueous mineral acid to gel the mixture and drying and firing the gel paste. The proportions and adsorption capacities of the components can be selected to tailor the adsorption characteristics of the composites to selectively remove targeted constituents such as acrolein and 1,3-butadiene in tobacco smoke. Methods for making filters and smoking articles using the composites, as well as methods for smoking products comprising the composites, are also provided.

    摘要： Cut filler compositions, cigarettes, methods for making cigarettes and methods for smoking cigarettes are provided, which involve the use of a composite mesoporous/microporous material. The composite material is capable of removing at least one constituent from tobacco smoke, preferably selectively. The composite material may also be used for removing at least one constituent from tobacco smoke through sorption and/or catalysis. The composite material comprises channels interconnecting at least one mesoporous region and at least one microporous region. The mesopores of the composite material may further comprise a carbon lining and/or be further functionalized with a surfactant. Alternatively, the composite material may further comprise a metal, a metal oxide, or mixtures thereof.
