Embodiment Construction

[0036] The present invention provides cut-and-fill tobacco compositions, cigarettes, methods of making cigarettes and methods of smoking cigarettes involving the use of oxyhydroxides capable of decomposing during smoking into at least one product capable of being used as An oxidizing agent for the conversion of carbon monoxide to carbon dioxide and / or as a catalyst for the conversion of carbon monoxide to carbon dioxide. By means of the present invention, it is possible to reduce the amount of carbon monoxide in mainstream smoke, thereby also reducing the amount of carbon monoxide reaching the smoker and / or released as second-hand smoke.

[0037] The term "mainstream" smoke refers to the gaseous mixture that passes through the tobacco rod and emerges from the filter end, ie the amount of smoke that emerges during smoking or is drawn from the mouth end of the cigarette. Mainstream smoke consists of smoke inhaled through the lit area of ​​a cigarette as well as through the cigar...

Abstract

The present invention provide cut filler compositions, cigarettes, methods for making the cigarettes and methods for smoking the cigarettes, which involve the use of an oxyhydroxide compound that is capable of decomposing to form at least one product capable of acting as an oxidant for the conversion of carbon monoxide to carbon dioxide, relating to a cigarette combustion area (wherein Fe2O3 nanoparticles acts as an oxidant) while cigarettes smoking, a thermal decomposition area (wherein Fe2O3 nanoparticles acts as a katalyst ) while cigarettes smoking and correlated reactions happening in the areas.

Description

technical field [0001] Broadly, the present invention relates to methods of reducing the amount of carbon monoxide in the mainstream smoke of a cigarette when smoked. More particularly, the present invention relates to cut-fill tobacco compositions, cigarettes, methods of making cigarettes, and methods of smoking cigarettes, involving the use of oxyhydroxides which decompose during smoking to produce one or more A product capable of acting as an oxidizing agent for the conversion of carbon monoxide to carbon dioxide and / or as a catalyst for the conversion of carbon monoxide to carbon dioxide. Background technique [0002] Different approaches to reducing the amount of carbon monoxide in the mainstream smoke of cigarettes during smoking have been proposed. For example, British Patent 863,287 describes a method of treating tobacco prior to manufacture of a tobacco product in order to remove or modify incomplete combustion products when the tobacco product is smoked. Addition...
