Abstract
A tobacco smoking mixture is provided that includes tobacco and at least one inorganic particulate material. The at least one inorganic particulate material is effective to reduce the temperature of a burning portion of the tobacco smoking mixture upon combustion/pyrolysis thereof. The at least one inorganic particulate material can be an inorganic carbonate, an inorganic hydrate, an inorganic oxide, an inorganic phosphate, a carbon material or combinations thereof.
Claims45
A tobacco smoking mixture, comprising tobacco and at least one inorganic particulate material selected from the group consisting of graphite, fullerene, carbon foam and graphitic foam, wherein the at least one inorganic particulate material is present in an amount effective to reduce the temperature of a burning portion of the tobacco smoking mixture upon combustion/pyrolysis thereof and the tobacco comprises at least about 50% by weight based on the total weight of the tobacco smoking mixture.
A method for manufacturing a tobacco smoking mixture for use in a smoking article, comprising the step of spraying tobacco with at least one inorganic particulate material selected from the group consisting of carbon foam, graphitic foam, graphite and fullerene, wherein the at least one inorganic particulate material is added to the tobacco smoking mixture in an amount effective to reduce the temperature of a burning portion of the tobacco smoking mixture upon combustion/pyrolysis thereof and the tobacco comprises at least about 50% by weight based on the total weight of the tobacco smoking mixture.
A method for manufacturing a tobacco smoking mixture for use in a smoking article, comprising the steps of mixing at least one inorganic particulate material with tobacco, and casting the mixture into a sheet, wherein the at least one inorganic particulate material is selected from the group consisting of graphite, fullerene, carbon foam and graphitic foam, and the inorganic particulate material is added to the mixture in an amount effective to reduce the temperature of a burning portion of the tobacco smoking mixture upon combustion/pyrolysis thereof and the tobacco comprises at least about 50% by weight based on the total weight of the tobacco smoking mixture.
A method for manufacturing a tobacco smoking mixture for use in a smoking article, comprising the steps of mixing at least one inorganic particulate material with tobacco, and casting the mixture into a sheet, wherein the at least one inorganic particulate material is selected from the group consisting of graphite, fullerene, carbon foam and graphitic foam, and the inorganic particulate material is added to the mixture in an amount effective to reduce the temperature of a burning portion of the tobacco smoking mixture upon combustion/pyrolysis thereof, wherein the inorganic particulate material is added to a tobacco slurry, the slurry is formed into sheet material, the sheet material is cut into strips and the strips are formed into a tobacco rod or the strips are added to tobacco which is formed into a tobacco rod, the tobacco rod is enclosed within cigarette paper to form a tobacco rod/cigarette paper assembly, and cigarette rods are formed by severing the tobacco rod/cigarette paper assembly into sections.
