Abstract
The present invention relates to an adsorbent for removing harmful substances from cigarette smoke, which is prepared from 60 to 90% of natural or synthetic zeolite molecular sieve with a low silica-alumina ratio (larger than 2.5) and 10 to 40% of molecular sieve with a high silica-alumina ratio (larger than 40) which are uniformly mixed. The adsorbent can be added in a filter tip of a general filter-tipped cigarette according to the quantity of 0.02 to 0.20g each cigarette. The weight of tar in cigarette smoke can be reduced by above 42%, the content of nicotine can be reduced by above 31%, and harmful substances, such as CO, aldehyde and aromatic hydrocarbon, etc. can also be effectively removed from the cigarette smoke.
Description
The present invention relates to a kind of adsorbent of molecular sieve, specifically provide a kind of can removing effectively and mainly contain the adsorbent of molecular sieve that harmful substances is used in the cigarette smoke.
For a long time, be the harmful substance in reduction or the elimination cigarette smoke, as the murder by poisoning of tar, nicotine etc., people have carried out making great efforts in large quantities, and taked various measures and method, its technology the simplest and that widely adopted is to add a filter tip by acetate fiber system on cigarette.But, therefore constantly propose to improve the technology of cigarette filter performance again because this method still can not be got rid of the harmful substance in the cigarette smoke effectively.As before filter tip, increasing layer of active carbon or carbon fiber adsorption and catalytic combustion layer, in filter tip, add adsorbents (CN92105073.9) such as montmorillonite, zeolite, and use adsorbent of molecular sieve technology such as (JP1990 308784).But prior art is to the poisonous pest in the cigarette smoke, as aromatic hydrocarbons, aldehydes etc. to remove ability lower.
The object of the present invention is to provide and a kind ofly can remove the adsorbent that mainly contains harmful substances, tar, nicotine and aldehydes, aromatic hydrocarbons, CO etc. in the cigarette smoke effectively.Adopt this technology simultaneously, can keep smoking cigarette strength, improve mouthfeel.
Of the present inventionly remove harmful substance adsorbent in the cigarette smoke, remain and adopt zeolite molecular sieve, it is characterized in that it being to select for use high silicon to cooperate the compound molecule sieve adsorbant that constitutes by a certain percentage with natural or synthesizing low silicon aluminum ratio zeolite molecules aluminium sieve than molecular sieve as adsorbent.Natural or synthesizing low silicon aluminum ratio zeolite molecular sieve can be selected X type, Y type or the modenite of silica alumina ratio greater than 2.5 (2.5～10) for use, and the high silica alumina ratio molecular sieve can utilize X type, Y type, modenite or ZSM-5 zeolite to be prepared into sial through the molecular sieve greater than 40 (40～200) through dealumination treatment, two kinds of molecular sieves are pressed low silica-alumina ratio molecular sieve 60～90%, the weight ratio of high silica alumina ratio molecular sieve 10～40% cooperates, again through fully mixing, make microgranular (50～80 order), or Powdered (80～100 order), be adsorbent of the present invention.
Adsorbent of the present invention, its using method is very easy, can be in the preparation process of cigarette filter the absorbent powder of the invention described above be modulated into slurries, be coated in equably on the raw fibre paper of system filter tip or with the absorbent particles layer and insert in the middle of the aldehydic acid fibrous filter, technology is made cigarette filter routinely again.The use amount of adsorbent of the present invention seldom contains 0.02-0.20g in every cigarette approximately.Because adsorbent of the present invention has high selection absorption property, so not only can remove a large amount of T/Ns (nicotine) from cigarette smoke, can also remove various harmful substance compositions such as CO, acetaldehyde, methacrylaldehyde, benzene,toluene,xylene simultaneously.Below by example technology of the present invention is given to illustrate in further detail.
Example 1. preparation of adsorbent of the present invention
With commodity X type, Y zeolite adopt natural or synthesizing flokite (sial＞2.5) as low silica-alumina ratio zeolite raw material;
2. with above-mentioned X type and y-type zeolite EDTA solution-treated, modenite and ZSM-5 zeolite carry out dealumination treatment (the treatment fluid consumption is about 3 times of solid material) with 2NHCl, carry out repeatedly obtaining the high silica alumina ratio zeolite molecular sieve of silicon/aluminium＞40 more than 3 times;
3. 1 low silica-alumina ratio zeolite is cooperated by certain weight ratio with 2 high silica alumina ratio zeolite, through being ground into 80-100 order powder or 50-80 order particulate, promptly make adsorbent of the present invention again.The composition such as the table 1 of concrete adsorbent 1,2,3,4:

Comparative example 1: the preparation of adsorbent of molecular sieve
As a comparison, press the prepared molecular sieve of method of example 1, prepare out 1,2,3,4 adsorbents of comparative example by different proportion, its composition is also listed in the table 1.
Example 2, performance of the adsorbent of the present invention
Utilize 1,2,3,4 prepared adsorbents of example 1, can add a small amount of (2%) binding agent (sodium carboxymethylcellulose) and an amount of water and be deployed into the 20%-50% slurries, on Filter tip shaping machine, be coated onto equably on the fiber base paper, make the filter tip that contains adsorbent, and it is long to be cut into 10mm, combines with common acetate fiber filter tip 10mm and makes composite cigarette filter tip.
Use above-mentioned filter tip to make cigarette, utilize the method for the various compositions of conventional analysis cigarette smoke, analyze the composition of cigarette smoke after by the filter tip that is added with adsorbent of the present invention, it the results are shown in table 2.
Comparative example 2, the technology beyond the present invention is to the performance of filtration of cigarette smoke.
Press the method for example 2, utilize comparative example 11,2,3,4 prepared adsorbents to make cigarette.Utilize common system filter tipped cigarette technology again, preparation acetate fiber filter tip is the common cigarette of 20mm, and presses the fiber base paper 10mm of example 1 and the filter tip of acetate fiber 10mm, makes white mouth cigarette again.
Above-mentioned made various cigarettes and example 2 are carried out same test under the same conditions, its by filter tip after the result of exhaust gas components with listing in table 2.
