Publication number: 20040173231Abstract: A cigarette sidestream smoke treatment material made from a sheet of non-combustible active components provides a porous structure capable of treating sidestream smoke. The treatment material, as used in combination with a cigarette, provides a low sidestream smoke emitting cigarette unit. The material has a porosity which encourages a conventional free-burn rate of a conventional cigarette. The material may comprise a sorbent capable of sorbing components of the sidestream smoke, and an oxygen storage component which releases oxygen at free-burn rate temperatures to ensure that conventional free-burn rate is maintained and to enhance the oxidation treatment of the adsorbed non-aqueous components. Preferably, an oxidation catalyst is included in the material and most desirably the oxygen storage component may also function as the oxidation catalyst. Particularly preferred materials which perform the dual function are oxides of cerium.Type: ApplicationFiled: March 22, 2004Publication date: September 9, 2004Applicant: Rothmans, Benson & Hedges Inc.Inventors: Larry Bowen, Stanislav M.

Publication number: 20040007242Abstract: The invention relates to a low ignition propensity cigarette having a self-extinguishing cigarette wrapper which is capable of self-extinguishing the cigarette. The cigarette wrapper comprises an oxygen storage and donor metal oxide to support and maintain free-burn of the self-extinguishing cigarette while retaining the low ignition propensity property of the self-extinguishing cigarette wrapper. The invention further relates to a low sidestream smoke cigarette having low ignition propensity properties. The wrapper has a composition which reduces sidestream smoke from a burning cigarette and comprises in combination, an oxygen storage and donor metal oxide catalyst and an essentially non-combustible finely divided porous particulate adjunct for the catalyst. The sidestream smoke reducing composition reduces porosity of the wrapper to render the cigarette as self-extinguishable.Type: ApplicationFiled: April 22, 2003Publication date: January 15, 2004Applicant: Rothmans, Benson & Hedges Inc.Inventors: Warren Finlay, Stanislav M.

Publication number: 20030114298Abstract: A process that provides a catalytic rare earth oxide-coated microporous free-flowing bulk particulate wherein the amount of metal oxide coated thereon is high, without jeopardizing the effectiveness of the material. The rare earth metal oxide coated on the outer surface may be in the range of 20 to 70% by weight based on the total equivalent rare earth metal oxide and microporous particulate material content. In particular, a zeolite free-flowing bulk particulate having high loadings of rare earth metal oxide tends to be quite stable. For instance, when the rare earth metal oxide-coated zeolite free-flowing bulk particulate has been heat treated at temperatures less than about 200° C. and then slurried in water, typically, less than 30% by weight of the rare earth metal oxide (based on the total equivalent rare earth metal oxide content) is found to leach into water. This material has been found to have minimal leachability when heat treated above about 400° C.Type: ApplicationFiled: September 13, 2002Publication date: June 19, 2003Applicant: Rothmans, Benson & Hedges Inc.Inventors: James L.
