Continuous Process For Impregnating Solid Adsorbent Particles Into Shaped Mirco-Cavity Fibers
US Patent:
2010017, Jul 15, 2010
Filed:
Mar 22, 2010
Appl. No.:
12/728725

Assignee:

International Classification:
A24F 1/20, A24B 1/00
US Classification:
131207, 131360
Abstract:
A process of impregnating fine adsorbent particles such as carbon dust or APS silica gel powder into the micro-cavities of shaped fibers comprises the steps of continuously conveying shaped fibers with micro-cavities to a reservoir of the fine adsorbent particles. The fibers pass through the reservoir to thereby produce relative motion between the fibers and the particles. Additionally, impact forces are created between the shaped fibers and the fine particles to assist in impregnating the particles into the micro-cavities of the fibers. Any excess particles are removed from the fibers outside the reservoir, and subsequently the shaped fibers impregnated with fine adsorbent particles are collected for later use in filter applications such as cigarette filter and air filter applications, for example.

Adsorbents For Smoking Articles Comprising A Non-Volatile Organic Compound Applied Using A Supercritical Fluid
US Patent:
8114475, Feb 14, 2012
Filed:
Jul 10, 2009
Appl. No.:
12/501049
Inventors:
Charles Thomas - Richmond VA, US
Assignee:
Philip Morris USA Inc. - Richmond VA
International Classification:
B05D 7/00, B05D 7/24, A24D 3/08, A24D 3/02
US Classification:
427212, 4272133, 131331, 131332, 131280
Abstract:
A surface-modified adsorbent and a process for making a surface-modified adsorbent are provided. The process involves providing an adsorbent and a non-volatile organic compound to a vessel, adjusting the temperature and/or pressure to provide supercritical conditions for a supercritical fluid, and introducing the supercritical fluid into the vessel. The supercritical fluid dissolves the non-volatile organic compound, and impregnates the adsorbent with the non-volatile organic compound. The surface-modified adsorbent can be used, for example, in cut filler compositions, cigarette filters, and smoking articles. Methods for making cigarette filters, cigarettes and for smoking a cigarette comprising the surface-modified adsorbent are also provided. The surface-modified adsorbents can be used to remove one or more selected components from mainstream smoke, without removing other components, such as those that contribute to flavor.
Cigarette Filter With Beaded Carbon
US Patent:

International Classification:
A24D003/04
US Classification:
131/341000, 131/342000, 131/344000
Abstract:
A smoking article such as a cigarette comprises a tobacco rod and a filter component having a cavity filled with spherical beaded carbon. As mainstream tobacco smoke is drawn through the filter component, targeted gas phase smoke constituents are removed as the smoke passes through the carbon. During the filter manufacturing process the spherical beaded carbon flows like a liquid and substantially completely fills the cavity. Point-to-point contact between the spherical beads together with substantially complete filling of the cavity produces minimal channeling of ambulatory gas phase as well as maximum contact between the gas phase and the carbon surface of the spherical beads during smoking.
Activated Carbon Fiber Cigarette Filter

International Classification:
A24D001/04
US Classification:
131/202000, 131/341000
Abstract:
A cigarette filter for removing gas phase constituents from mainstream cigarette smoke as the smoke is drawn through the filter primarily comprises an activated carbon fiber filter section including a bundle of activated carbon fibers. Particulate adsorbent materials such as granules, beads or course powders may be dispersed amongst the activated carbon fibers to aid in removal of the gas phase constituents. Additionally, the activated carbon fiber filter section may be used in combination with a separate bed or beds of particulate adsorbent material. In one embodiment, the activated carbon fibers are positioned within a helical groove on the outside of a threaded rod within the activated carbon fiber filter section. Relatively smaller amounts of activated carbon fibers produce the same smoke constituent reduction as larger amounts of particulate adsorbent material.
Cigarette With Adsorbent At Tip End Thereof
US Patent:
2004007, Apr 29, 2004
Filed:
Oct 25, 2002
Appl. No.:
10/280473
Inventors:
Charles Thomas - Richmond VA, US
International Classification:
A24D001/04
US Classification:
131/202000, 131/361000
Abstract:
A zone or plug of porous adsorbent material, primarily activated carbon, is placed in the tobacco rod of a cigarette a short distance from the lighting end thereof. The amount of activated carbon is sufficient for effective removal of volatile smoke constituents while allowing the cigarette to burn continuously. The activated carbon traps volatile smoke constituents in close proximity to the burning coal in the first puffs of the cigarette. As the cigarette continues to burn, the burning coal consumes the activated carbon. The adsorbed smoke constituents are effectively removed without releasing them back into the mainstream smoke. Following the consumption of the activated carbon in the tobacco rod, the cigarette is unchanged from a cigarette of conventional design.
