Description

A kind of nicotine-filtering medium for cigarette composition and method of making the same
Field that the present invention belongs to
The present invention relates to a kind of nicotine-filtering medium for cigarette composition and method of making the same, particularly a kind ofly can apace cigarette be inhaled the CO that produces in the combustion process and change into CO 2And reduction sucks the interior tar content of human body and nicotine-filtering medium for cigarette of other harmful dust and gas and preparation method thereof effectively.
Background of invention
CO is mainly reflected in the following aspects to the harm of human body: after human body sucks CO, CO combines with hemoglobin in the blood, cause human body anoxia, can cause nonvolatil infringement to people's central nervous system in the course of time, cardiovascular system also may affect adversely.Recently, people have noticed the harm of smoking to health more and more, the harmful substance that produces for smoking process for example tar, nicotine, dust etc. had many reports to the harmfulness of human body, and had taked multiple measure to reduce the infringement of these materials to the smoker.For example, on cigarette type and tobacco leaf auxiliary material, work hard, on cigarette, add filter tip, on filter tip, add active carbon filtering layer etc.But people have usually ignored CO, the H that produces in the smoking process 2Toxic gas such as S, aldehydes is to smoker's harm, wherein especially with CO to the harm of human body for the most very.Result of study shows, the CO amount that every cigarette produces is for about 18mg, and the content that the smoker whenever has a suck of CO in the gas of cigarette inspiration is not less than 1000ppm, if the people breathes in this environment continuously, will cause serious poisoning even stupor less than 60 minutes.Therefore, for the smoker, the CO that sucks in the smoking process is very serious to the harm of its health.In addition, raising along with industrialization degree, the air pollution degree aggravation, with CO is the CO of industrial and mining enterprises in production engineering and the accidental release of other pernicious gases of the raw material or the energy, the generation of fire CO in early stage, and the use of a large amount of fossil fuel, for example the tail gas of vehicular emission makes airborne pernicious gas such as CO, H 2The concentration of S etc. increases, and has influenced human beings'health.
U.S. Pat P5,258,340 disclose and a kind of CO to be changed into CO 2Catalyst, this catalyst comprises palladium salt, molybdenum salt or tungsten salt; Any slaine in copper, nickel or the iron; The consumption of slaine should be enough to make described being in behind the gas of oxidized reproducibility to go back the palladium salt of ortho states, molybdenum salt or tungsten salt, when contacting with reducibility gas in air, is oxidized to its oxidation state; And the carrier of the described mixture of load.As described in this US Patent specification, when the concentration of CO was 0.2% (volume), this catalyst changed into CO with CO 2Speed be 42 seconds.Such response speed is skimble-skamble for eliminating the CO that produces in the smoking process to smoker's harm.In addition, tar, dust, the H of this catalyst to producing in the smoking process 2S etc. do not have action effect.Simultaneously, the regeneration rate of reactive metal that the reactive metal (Pd, Mo, W) of going back ortho states is changed into its oxidation state is also undesirable, and therefore, this catalyst is not suitable in the cigaratte filter.
Goal of the invention
An object of the present invention is to provide and a kind ofly can apace the CO that produces in the smoking process be changed into CO 2And reduce the tar that produces in the smoking process, the nicotine-filtering medium for cigarette composition of dust effectively.
Another object of the present invention provides and a kind ofly can reduce the harmful toxins that produces in the smoking process does not influence the tobacco taste simultaneously again to smoker's harm nicotine-filtering medium for cigarette composition effectively.
A further object of the present invention provides the aforesaid nicotine-filtering medium for cigarette method for compositions of preparation.
A further object of the invention provides a kind of energy fast and continuously the CO in the environment is changed into CO 2And reduce the nicotine-filtering medium composition of other reducibility gas content effectively.
