    摘要： A smoking article composition and a method of making a smoking article composition comprising tobacco cut filler, cigarette paper and/or cigarette filter material further comprising a catalyst capable of converting carbon monoxide to carbon dioxide, wherein the catalyst comprises nanoscale catalyst particles dispersed within a porous aluminosilicate matrix. The catalyst can be formed by combining nanoscale catalyst particles or a metal precursor solution thereof with an alumina-silica sol mixture to form a slurry, gelling the slurry to form the co-gel, heating the co-gel to form a catalyst comprising nanoscale catalyst particles dispersed within a porous aluminosilicate matrix. The catalyst can be incorporated in tobacco cut filler, cigarette paper and/or cigarette filter material by spraying, dusting and/or immersion.

    摘要： A process for making modified activated carbon from an activated carbon substrate. The activated carbon substrate is pre-treated to make an exposed surface of the activated carbon substrate substantially hydrophilic, coated with a carbon precursor to form a coated activated carbon, and then the coated activated carbon substrate is heated to carbonize the carbon precursor to from the modified activated carbon. The modified activated carbon comprises a uniform porous carbon membrane formed on an exposed surface of the activated carbon substrate. The carbon membrane can mediate the absorption and/or adsorption kinetics of the activated carbon substrate. The modified activated carbon, which can be incorporated into one or more components of a cigarette, can selectively remove gaseous constituents from mainstream smoke during smoking.

    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.
