Description of the Invention: [Technical Field to Which the Invention Is Alonged] The present invention relates to a cigarette filter. [Prior Art] In the past, in order to reduce C0 (-carbon oxide) in grass mainstream tobacco, it is necessary to add a noble metal catalyst or metal oxide catalyst or Wacker in a filter, shredded tobacco, rolled paper, or the like. Catalyst. For example, a partial reduction additive such as Fe2〇3 (iron oxide) which acts as a catalyst for converting carbon monoxide into carbon dioxide is used as a filler composition (Patent Document 1). Further, a catalyst such as CuO-ZnO-Ce〇2 (copper oxide-zinc oxide-yttria) is used in a cigarette filter to oxidize C0 (Patent Document 2). However, these documents only mention the catalysts that can reduce C0 when using a mode 1 gas, but the control of the amount of C0 in the mainstream cigarette smoke is not disclosed. . Further, a cigarette filter in which the surface of the active carbon particle is coated with copper and the surface thereof is covered with platinum is generally known (Patent Document 3). Although it is disclosed that such a cigarette filter can reduce the vapor component, it has no effect on the gas component. Furthermore, it is shown that the amount of C0 will increase. Further, a tobacco smoke filter in which one or more kinds of copper, molybdenum, manganese, cobalt, zinc, and iron are added to activated carbon has been disclosed (Patent Document 4). Also disclosed is a carrier which carries an Au-Ti (gold-titanium) oxide or an Au-Zn (gold-zinc) oxide on a carrier (Patent Documents 5 and 6). However, when using these carriers, the C0 reduction rate is only about 20 to 48%. 4 321165 200944141 As mentioned above, there has been no known cigarette filter that can effectively control the amount of C0 emissions in mainstream tobacco tobacco. [Patent Document 1] Japanese Patent Publication No. 2005-522206 [Patent Document 2] US Patent Application Publication No. 2-6/〇289〇24 [Patent Document 3] 曰本特开平 7_25〇666号 [Patent [Patent Document 5] U.S. Patent Application Publication No. 2 〇〇 5_5222 〇 6 [Patent Document 5] U.S. Patent Application Publication No. 2 〇〇 7/〇 2 〇 〇 ❹ ❹ ❹ [ [ 专利 专利 专利 专利 专利 专利 专利 专利2〇〇7/〇215166 Specification [Invention] The object of the present invention is to provide a cigarette filter which can effectively control the amount of c〇 discharged from tobacco mainstream smoke without affecting the flavor component. A cigarette filter according to the present invention is characterized in that: an X»clamping portion containing a carrier 10 is disposed, and the carrier catalyst is disposed on a nozzle side of a straw (tabacc〇r〇d), and (The ratio of the specific surface area of the micro p〇re/the specific surface area of the meso-macropore) is 〇. 5 to 1 〇.〇, (fine pore volume / medium-macropores) The pore volume ratio is a porous carrier of 〇.3 to 6. 〇, and the carrier is selected from the group consisting of Pt (platinum), Pd (palladium), Au (gold), Rh (铑), Ru (钌). ), Ag (silver), Ti (titanium), Fe (iron), Co (cobalt), Cr (chromium), Ni (nickel), Cu (copper), Zn (zinc), Mn (manganese), Zr (鍅) ), V (vanadium), Nb (sharp), Mo (turn), Ce (钸), Hf (to), Ta (group), W (he), Re (chain), Os (planing), Ir (铱) ), Y (钇), Tc (鍀), B (boron), Mg (magnesium), Na (sodium), 5 321165 200944141 A1 (aluminum), Ca (calcium), strontium (potassium), Si (矽) Metal catalysts of Sn (tin), Ge (germanium), Sr (lithium), Rb (diligent and ln (indium), metal oxide catalysts containing oxides of these metals and composite oxides And a portion of the carrier catalyst of at least one catalyst formed by the Wacker catalyst. According to the present invention, it is possible to provide a cigarette filter capable of effectively controlling the C0 emission amount in the tobacco mainstream smoke without affecting the flavor component. [Embodiment] In the present invention, the porous carrier may, for example, be a porous carbon material (coconut activated carbon, bituminous coal, synthetic carbon, carbon fiber, meso porous carbon). , carbon sheet, carbon molecular sieve, etc., coke, carbon black, carbon nano tube. Carrier granules from gas permeability From the viewpoint of (permeabi i ity resistance), it is preferably from 200 to 2000 #m. The carrier may be a honeycomb structure or a fibrous one. In the present invention, in terms of a catalyst 'Can be used: selected from Pt, Pd, Au, Rh and Ru' which are noble metal catalysts, CuO, ZnO Ce〇2, Mn〇2 and AgO' which are metal oxide catalysts and groups formed by facker catalyst At least one of them. For the carrier, the ratio of the specific surface area of the micropores to the specific surface area of the medium to large pores is 0.5 to 1.0, and the ratio of the pore volume of the micropores to the pore volume of the large pores is 〇. 3 to 6. 〇. Here, the micropores refer to those having a pore diameter of 2 nm or less, the mesopores having a pore diameter of 2 to (10), and the macropores being those having a pore diameter of 50 nm or more. 6 321165 200944141 The total specific surface area is determined by the BET method (Brunner-Emmett-Teller method), Bruce-Emmett-Taylor method. The specific surface area of the medium-macropores was determined by the DH method. The specific surface area of the micropores can be obtained by subtracting the specific surface area of the medium-macropores from the total specific surface area. The total pore volume is determined by the BET method. The pore volume of the medium-macropores was determined by the DH method. The pore volume of the micropores can be obtained by subtracting the pore volume of the medium-macropores from the total pore volume. In the case of the porous carrier, the ratio of (the specific surface area of the micropores/the specific surface area of the medium to large pores Φ) or the ratio of the pore volume of the micropores to the pore volume of the medium to large pores escapes the above range. In this case, it is indicated that the degree of dispersion of the catalyst is lowered and the particle diameter of the catalyst is increased, so that the activity of the catalyst is lowered, so that C0 cannot be removed. In the present invention, a portion containing activated carbon having a specific surface area of 700 to 2000 m 2 /g (hereinafter referred to as "highly activated carbon") may be provided in the front portion of the portion containing the catalyst. If the site containing the highly activated carbon is placed in the front part of the site containing the catalyst, the catalyst activity can be maintained for a long time. 。 In the present invention, the surface area of the catalyst is preferably 0.6 m2 or more, more preferably 2. 4 m2 or more. If the surface area of the catalyst is 0.6 m2 or more, C0 2 or more can be removed, and if it is 2.4 m2 or more, nearly 10% can be removed (3). Here, the surface area of the catalyst can be obtained by the following formula: (catalyst surface area) = (specific surface area of the catalyst) [m2 / g] X (loading amount of the catalyst) [g] In the present invention, The particle diameter of the medium is preferably 20 nm or less, more preferably 5 nm or less. When the particle diameter of the catalyst is 20 nm or more, the catalytic activity is lowered. 7 321165 200944141 The smaller the particle size of the catalyst, the higher the activity of the catalyst. The particle size of the catalyst can be calculated from chemical adsorption (pulis) by a pulse method. For the adsorption of the chemical seed, for example, C0 is used. In the present invention, the carrier can be directly filled and used for the filter, or it can be dispersed in shredded tobacco or rolled paper. The following embodiments are described below with reference to the drawings. The composition of the cigarette used in the test is shown in Fig. 1 (a) and (b). The test cigarette of Fig. 1(a) is equipped with a carrier 1 as a cavity.

The reason for setting this condition is that the catalyst activity is lowered when the system 1 is overspeed. The penetration rate (1^NlC) of ΠF iu·, transmittance (H-C0) and final test (nicotine) can be expressed by the following formula. 1, E, C0 = C丨々. (it匕, ". Yin. — 罝裘 ^ ^ 1 indicates the amount of C0 discharged after carrying the catalyst, Co indicates the amount of C0 discharged from the early roll), 8 321165 200944141 lE.Nic-Ni/No (here, Ni represents the amount of the detected discharge after the catalyst is carried, and No represents the amount of nicotine discharged per unit.) First, as the carrier catalyst 1 in the test cigarette of Fig. 1(a), activated carbon is used. Those who carry Pt (referred to as Pt-activated carbon for short) or those who hold silica gel with Pt (referred to as Pt-based rubber). The method of carrying is to use the method of impregnation (i mpregna ti on). In the figure 2, the transmittance of (3) or nicotine for the amount of Pt-activated carbon or Pi: colloidal support (the amount of catalyst supported) is shown. From Fig. 2, when activated carbon is used as a carrier, Compared with the use of tannin as a carrier, the reduction rate of C0 is high under the same amount of catalyst. • Secondly, the use of activated carbon to carry Pt (abbreviated as Pt-activated carbon), or activated carbon The carrier carrying Pt/Rh (=5/1) (abbreviated as Pt/Rh-activated carbon) is used as the carrier catalyst 1 in the test cigarette of Fig. 1(a). P The penetration rate of C0 and the penetration rate of nicotine in the amount of activated carbon or Pt/Rh activated carbon. As can be seen from Fig. 3, when Pt-activated carbon is used, Pt/Rh is used. In the case of activated carbon, the reduction rate of C0 is high under the same amount of catalyst. On the other hand, in terms of the penetration rate of nicotine, the reduction rate does not differ by the catalyst. In the filter unit, only the test cigarette of Fig. 1(a) carrying the Pt activated carbon is placed, or the high-activated carbon having a specific surface area of 1,700 m2/g is disposed in the front portion of the filter portion, and is disposed in the subsequent stage. In the configuration of the test cigarette of Fig. 1(b) carrying Pt activated carbon, the smoking of the tobacco rod 10 of a plurality of branches was repeatedly performed to investigate the change in the amount of C0 gas permeation. 9 321165 200944141 By the 4th order, the smoking was indicated. The relationship between the number of counts and the amount of C 〇 is discharged. In the case where the (4) (4) activated carbon is arranged in the front stage of the high-activated scorpion 1 (8), the effect of (3) can be continuously reduced. The relationship between the surface area of Pt held and (3) = :UE-C0). As can be seen from Figure 5, if you want to When the reduction is made as a target, the Pt surface area is made into (10)2, and the reduction of C0 by 10% is made as the target, and the product is made into 2.4m2 or more. The soup π is made up of various activated carbons to make it carry. h to modulate the catalyst to evaluate the performance of the supported catalyst. Shishan, as a carrier, prepares two kinds of activated carbons (activated carbon 2). The total pore volume of the macropores in these active systems is different. The preparation of the activated carbon carbon-activated carbon) carries the particle size medium. Table 1 shows the Pt dispersion and Pt of these supported catalysts.
