摘要:
A wrapper for a smoking article includes a web including cellulosic fibers and a catalyst modified web-filler incorporated into the web. The catalyst modified web-filler includes a web-filler supporting a nanoparticle carbon monoxide catalyst. The nanoparticle carbon monoxide catalyst can be a nanoparticle iron oxide catalyst. Also provided is a smoking article including a cigarette tobacco rod having a wrapper including a web, a web-filler, and a nanoparticle carbon monoxide catalyst, the web-filler supporting the nanoparticle catalyst. A method of making the wrapper and a method of making a smoking article utilizing the wrapper are also provided.
摘要:
Cut filler compositions, cigarettes, methods for making cut filler compositions and cigarettes, and methods for treating mainstream tobacco smoke of cigarettes are provided that use catalyst particles capable of converting carbon monoxide to carbon dioxide. The catalyst particles are supported on tobacco powder. The tobacco powder supported catalyst particles can be prepared by dry admixing the catalyst particles and tobacco powder or by combining a dispersion of catalyst particles with the tobacco powder.

A wrapper for a smoking article includes nanoparticle spinel ferrite catalyst and a web including cellulosic fibers and an optional web-filler. The web-filler can be a modified web-filler which incorporates the spinel ferrite catalyst. The nanoparticle spinel ferrite catalyst can be a nanoparticle manganese-copper-iron oxide catalyst incorporated in the wrapper and/or a tobacco cut filler. Also provided is a smoking article including a cigarette tobacco rod having a wrapper including a web, a web-filler, and a nanoparticle spinel ferrite catalyst, the web-filler optionally supporting the nanoparticle catalyst. A method of making the wrapper and a method of making a smoking article utilizing the wrapper are also provided.
摘要:
A cigarette made from cigarette paper comprising a base web and at least one banded region comprising iron oxide nanoparticles. The at least one banded region has a porosity less than a porosity of the base web such that the at least one banded region exhibits a slower burn rate compared to adjacent non-banded regions.
摘要:
Cigarette paper, methods for making cigarettes and methods for smoking cigarettes are provided, 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 and/or as a catalyst for the conversion of carbon monoxide to carbon dioxide. The oxyhydroxide compound and/or the product formed from the decomposition of the oxyhydroxide can be in the form of nanoparticles. The oxyhydroxide compounds can be represented by MOOH where M is a metal selected from the group consisting of transition metals, rare earth metals, and mixtures thereof.

A wrapper for a smoking article includes a web; and a patterned deposit on at least a portion of one surface of the wrapper, wherein the patterned deposit comprises catalyst particles. The patterned deposit can include a nanoparticle catalyst that is capable of catalyzing the conversion of a constituent gas component in the mainstream and/or sidestream smoke of the smoking article. The constituent gas component can be carbon monoxide and/or nitric oxide and the catalyst particles can be iron oxide. Also provided is a smoking article comprising a tobacco rod having a wrapper formed around the tobacco rod, the wrapper including a patterned deposit on at least a portion of one surface of the wrapper. A method of making the wrapper and a method of making a smoking article utilizing the wrapper are also provided.
