Definitions
- the present invention relates to a method of treating tobacco mainstream smoke and a smoking tool.
- a smoking article comprising a rod of a smoking material and a filter section connected to the rod, wherein the filter section includes means for collecting particulate matter in smoke generated from the smoking material rod into a collecting zone, and means for heating the collecting zone such that a nonvolatile material is maintained in the filter and a semi-volatile material is released from the filter (see Jpn. Pat. Appln. KOKAI Pub. No. 4-262773).
- An object of the present invention is to provide a method of treating tobacco mainstream smoke and a smoking tool that is capable of selectively removing carbon monoxide in tobacco mainstream smoke.
- a method of treating tobacco mainstream smoke according to an aspect of the present invention comprises: introducing tobacco mainstream smoke into a heated catalyst packed section packed with an oxidation catalyst containing copper oxide, and selectively removing carbon monoxide relative to nicotine among components of the tobacco mainstream smoke.
- the catalyst packed section is preferably heated to a temperature in a range of 200 to 350° C.
- a smoking tool comprises: a catalyst packed section packed with an oxidation catalyst capable of selectively removing carbon monoxide relative to nicotine among components of the tobacco mainstream smoke, into which tobacco mainstream smoke is introduced; and a heating means for heating the catalyst packed section.
- the oxidation catalyst is selected from the group consisting of Hopcalite (registered trademark), CuO/ZnO, CuO/ZnO 2 and CuO/CeO 2 .
- the heating means is set to heat the catalyst packed section to a temperature preferably in a range of 200 to 350° C., more preferably in a range of 200 to 280° C.
- the smoking tool of the present invention may comprise a cooling section which cools the tobacco mainstream smoke and/or a filter material which collects tar at a rear section of the catalyst packed section.
- the present invention makes possible to provide a method of treating tobacco mainstream smoke and a smoking tool capable of selectively removing carbon monoxide in tobacco mainstream smoke.
- FIG. 1 is a schematic view showing a state where a cigarette is attached to a smoking tool according to an embodiment of the present invention.
- FIG. 2 is a diagram showing selective filtration coefficient of nicotine to CO when various oxidation catalysts are used.
- FIG. 3 is a graph showing temperature of Hopcalite, and change in delivery rates of nicotine, CO and NO.
- FIG. 1 is a schematic view showing a device setup for performing an experiment in the state where a cigarette is attached to a smoking tool according to an example of the present invention.
- a cigarette single rod 10 is attached to the upstream of the smoking tool 1 , and an automatic smoking machine 20 is connected to a mouth-piece end of the smoking tool 1 .
- the smoking tool 1 comprises a catalyst packed section 4 packed with an oxidation catalyst 3 , a stainless tube 2 filled with glass wool (110 to 130 mg), and a filter material 7 which collects tar.
- a heater 5 serving as a heating means is provided around the catalyst packed section 4 .
- a first cooling section 6 is provided around the stainless tube 2 filled with glass wool.
- a second cooling section 8 is provided around the filter material 7 .
- the catalyst packed section 4 is packed with 200 mg of oxidation catalyst and capped with a stainless mesh.
- the catalyst packed section 4 is heated with the heater 5 to a predetermined experimental temperature and then left for 30 minutes.
- an aluminum bag is fitted to the automatic smoking machine 20 so as to introduce dilution air.
- the reason for introducing dilution air is that a certain amount of gas is necessary for CO measurement.
- a commercial cigarette single rod 10 is smoked under the condition of 17.5 ml per two seconds. Seven puffs and one clearing puff are performed.
- the dilution air introduced above and tobacco mainstream smoke generated through automatic smoking are collected in one bag. CO, CO 2 and O 2 are quantified with a portable gas analyzer (available from Horiba, Ltd.). The above experiment is repeated twice to determine the average value.
- the catalyst packed section 4 is packed with 200 mg of oxidation catalyst and capped with a stainless mesh.
- the catalyst packed section 4 is heated with the heater 5 to a predetermined experimental temperature and then left for 30 minutes.
- Eight aluminum bags are prepared for one experiment (seven puffs and one clearing puff) to collect smoke for each puff. After it is checked that there is no leakage, another aluminum bag prepared separately containing dilution air is fitted.
- a commercial cigarette single rod 10 is smoked under the condition of 17.5 ml per two seconds. Seven puffs and one clearing puff are performed, while the bag is changed for each puff. NO and NO x of the collected gas for each bag are quantified with a portable gas analyzer (available from Horiba, Ltd.). The above experiment is repeated twice to determine the average value.
- the oxidation catalyst used is Hopcalite (MnO 2 —CuO), CuO/ZnO, CuO/ZnO 2 , MnO/Fe 2 O 3 , ZrO 2 , ZrO 2 /CeO 2 , CuO/CeO 2 , or Cu, CuO/CeO 2 (each crushed product with a grain size of 0.5 to 2 mm).
- the experiment was performed with the catalyst packed section 4 heated to 350° C., and the selective filtration coefficients of components of the collected gas were determined.
- the selective filtration coefficient S_B/A between component A (for example, CO) and component B (for example, nicotine) is represented by the following expression:
- Table 2 and FIG. 3 show the following.
- the value of S_Nic./CO is substantially larger than 1, making it possible to remove carbon monoxide well selectively relative to nicotine.
