Abstract: The invention provides a modified adsorbent material impregnated with a metal oxide, which can be used in a filter element adapted for use in a smoking article. The modified adsorbent material exhibits increased filtration efficiency with respect to certain gas phase species of mainstream cigarette smoke. Exemplary adsorbent materials that can be modified according to the invention include activated carbon, molecular sieves, clays, ion exchange resins, activated aluminas, silica gels, meerschaum, and mixtures thereof. One example of a metal oxide is cerium oxide. Impregnation with a metal oxide can be accomplished by directly treating the adsorbent with a metal oxide or impregnating the adsorbent with a metal oxide precursor, such as cerium nitrate, followed by calcining the impregnated material to convert the precursor to the desired metal oxide. Methods of forming the modified adsorbent material and smoking article filters incorporating the modified adsorbent material are also provided.

Abstract: A non-combustion, chemical heat source includes a heat chamber having a closed end and an open end. The heat chamber includes an apertured heat cartridge disposed at the open end of the chamber, an abutment disposed at the closed end of the chamber, an activating solution, a frangible seal separating the activating solution and the heat cartridge. The heat cartridge includes metallic agents that may come in a variety of configurations. The heat source is activated when the heat cartridge is pushed through and breaks the frangible seal allowing contact between the metallic agents and the activating solution. The heat cartridge includes an aperture in the bottom of the cartridge and absorbent paper surrounding the metallic agents, both of which control the transfer of the activating solution into the metallic agents to cause the chemical reaction. The heat sources may be incorporated into smoking articles and may also be used to heat foods or beverages, in hand warmers, and to heat equipment or materials.

Abstract: A cigarette smoking article achieves very low levels of CO and other gas phase components by means of substantial air dilution, but has an acceptable pressure drop and sufficient delivery of particulate matter to provide a flavorful smoke. The filter has two sections, an upstream section which has substantially no pressure drop thereacross and a downstream section which provides substantially all the pressure drop of the filter. Dilution air is admitted to the upstream section of the filter to mix with mainstream smoke before it passes through the downstream section of the filter and thereby reduce the CO and gas phase levels in the smoke.

Abstract: The present invention provides a conductive substrate useful for Joule heating, such as in an electronic smoking article. Particularly, the invention provides a resistive heating element formed of a conductive substrate. The conductive substrate comprises an electrically conductive material and a carbonaceous additive, such as a binder material. The conductive substrate is carbonized in that it is subjected to calcining conditions to effectively reduce the carbonaceous additive to its carbon skeleton. It has been found that such carbonized substrate has surprisingly improved resistance properties in relation a substrate of the same formulation that is not carbonized. The carbonized substrate can include an aerosol precursor material. The formed resistive heating element can be included in an electronic smoking article to simultaneously provide resistive heating and aerosol formation with a single, unitary component.

Abstract: A smoking article, such as a cigarette, includes a carbonaceous heat source. A mouth end piece segment is located at the mouth end of the smoking article, and the mouth end piece segment allows the smoking article to be placed in the mouth of the smoker to be drawn upon. The smoking article further incorporates an aerosol-generating segment located between the heat generation segment and the mouth end piece segment. The aerosol-generating segment incorporates an aerosol-forming material (e.g., glycerin and flavors). The heat generation segment is in a heat exchange relationship with the aerosol-generating region such that heat generated by the burning fuel element acts to volatilize aerosol-forming material for aerosol formation. The carbonaceous heat source is in intimate contact with coarse, fine or ultrafine particles of materials such as cerium oxide, or mixtures of cerium oxide and palladium chloride.
