The optimized rare earth oxide catalyst has little influence on the suction taste of cigarettes.
Description
Technical field
The present invention relates to the application of rare earth oxide in tobacco leaf or pipe tobacco.
Background technology
Contain tar in the flue gas that produces during cigarette burning, tar is the mixture based on the complicated component of organic hydrocarbon, and harmful material is promptly arranged in the tar, and the benefit materials that keeps cigarette odor-absorbing and fragrance is arranged again.Because tar has infringement to health, tobacco management both domestic and external department has all formulated policy and the plan that reduces tar, and for example China national tobacco monopoly bureau stipulates that 2000 annual tar contents are reduced to 15mg/ and prop up, and 2005 annuals reach the level of 12mg.Reduce in each link that tar run through the development of cigarette enterprise and innovation work.
Through reducing the effort of tar for many years, present domestic Virginian-type cigarette tar is stabilized in 15 milligrams/basically.This situation has been kept the several years.Although reducing the main trend of tar can not change, but domestic cigarette enterprise is in the defocused certain stagnation that occurred on the contrary of falling through more than ten years, this is because reducing tar is a complicated system engineering, is inhaling flavor and style in the event maintenance cigarette of must holding concurrently when reducing tar is original.Virginian-type cigarette because of raw material sources in the higher flue-cured tobacco of intrinsic tar, when tar reaches 15 milligrams/, continue to take existing physics to fall burnt laser boring, two a slices again, high ventilative obbbin, high resistance to suction are chewed the inherence suction flavor that excellent technology has been difficult to keep Virginian-type cigarette again." reducing cigarette tar and reducing complex art method with put into practice) " tobacco science and technology .2001 (2) .-4-8 has done more detailed elaboration to this in one literary composition.
The another kind of burnt technology of falling adopts chemical means to handle tobacco leaf, this class chemistry falls Jiao and is subdivided into two kinds again, a kind of is to adopt plant extract to be sprayed on the tobacco leaf, CN1255307 " a kind of plant tar-reducing agent preparation method and purposes " for example, CN1258463 " a kind of health-care cigarette and manufacture method that reduces coke tar in cigarette and free-radical contents "; Another kind is mainly to adopt combustion adjuvants such as sylvite to fall Jiao, for example " several sylvite fall burnt effect analysis " Light Engineering Institutes Of Zhengzhou's journal: natural science edition 2001,16 (4) .-62-64, this class patent and periodical literature also have other forms of report.But burnt method falls in this two classes chemistry weak point is arranged also, plant extract is owing to have the characteristic of original plant, can coordinate to relate to very complicated adjusting incense process with cigarette odor-absorbing, most plant extract can only be effective at the cigarette of concrete a certain brand on the suction flavor, and it is invalid to the cigarette of other brands, because complicated blending and suction flavor coordination problem are difficult to solve, it is not enough that Jiao's work of deeply falling of plant extract is carried out, and it specifically is applied in the breakthrough that also needs in the industrialization in the theory and practice; Burnt effect falls in combustion adjuvant has many data to prove, but the addition of combustion adjuvant calculates and need fall burnt effect up to the 2-3% competence exertion with solid, such addition is inhaled flavor to flue-cured tobacco to be influenced too big, the consumer can't accept, the combustion adjuvant of excess makes cigarette burning too fast in addition, significantly reduced puff number, the consumer can not accept equally.Another controversial viewpoint is to think that existing chemistry falls burnt effect and stablizes inadequately.The present invention can be indirect hereinafter this phenomenon of explanation.This phenomenon can overcome.
Classical flue-cured tobacco physics falls burnt method falling the burnt 15mg/ of arrival when propping up level, because can not remedy the loss of further falling defocused suction flavor, it is weak to rely on physics to fall defocused strength again.And two class chemistry fall Jiao also because variety of issue is arranged, and substantive breakthroughs can not be arranged, and fall burnt work like this and relative stagnation just occurred.
Summary of the invention
The purpose of this invention is to provide the application of a kind of rare earth oxide catalyst in tobacco leaf or pipe tobacco, the puff number of not obvious change cigarette.Reduce tar in the cigarette smoke with new chemical catalysis method.A kind of catalyst provided by the invention can also reduce other harmful substances in the cigarette smoke.
Technical scheme of the present invention has following:
The application of catalyst in tobacco leaf or pipe tobacco, catalyst are the compound that contains rare earth element.
The application of catalyst in tobacco leaf or pipe tobacco, catalyst are rare earth oxide, inorganic salt of rare earth, rare earth organic salt single or that mix.
The application of catalyst in tobacco leaf or pipe tobacco, inorganic salt of rare earth are rare earth carbonate single or that mix, RE phosphate, rare-earth hydroxide.
The application of catalyst in tobacco leaf or pipe tobacco, rare earth organic salt are rare earth carboxylate single or that mix, rare earth hydroxycarboxylate, rare earth butene dioic acid salt, beta-diketon class rare-earth salts.
The application of catalyst in tobacco leaf or pipe tobacco, the application of catalyst in tobacco leaf or pipe tobacco, the consumption of percentage meter catalyst in tobacco leaf or pipe tobacco is 0.01-10% by weight.Preferred consumption is 0.1-8%, and preferred consumption is 0.3-5%.
The application of catalyst in tobacco leaf or pipe tobacco is used with combustion adjuvant, and the combustion adjuvant consumption of percentage meter in tobacco leaf or pipe tobacco by weight is 0.1-3%.Preferred consumption is 0.5-2%.
The application of catalyst in tobacco leaf or pipe tobacco is used with precious metal chemical complex, and the precious metal chemical complex consumption of percentage meter in tobacco leaf or pipe tobacco by weight is 0.001-2%.Preferred consumption is 0.01-0.5%.
Above-mentioned all catalyst granules are micron level or Nano grade.Diameter is in the 1-1000 nanometer.
Application in cigarette shreds does not have essential distinction to catalyst at tobacco leaf and catalyst, in the production of cigarettes process, tobacco leaf need add feed liquid, pipe tobacco needs perfuming, in reinforced or perfuming operation, catalyst can be added in tobacco leaf or the pipe tobacco, can on production line, increase the special equipment that adds catalyst when being necessary.
Catalyst participates in oxidation complicated in the cigarette burning, reduction, and cracking, polymerisation, thus tar-reducing agent can interrupt the chemical bond of the macromolecular tar of part and makes it to be decomposed into micromolecular non-tar material and reduce tar.The compound that contains rare earth element is widely used in oil and chemical field, but does not also contain the application of compound of rare earth element in the reducing cigarette tar and reducing field as the catalyst of generally acknowledging.The inorganic salts of rare earth are rare earth carbonate for example, at high temperature can be decomposed into rare earth oxide.Rare earth organic salt is rare earth monobasic, dicarboxylate for example, the rare earth hydroxycarboxylate, and the butene dioic acid rare-earth salts, beta-diketon class rare-earth salts at high temperature can be decomposed into rare earth oxide equally.
We according to cigarette burning before the content contrast of contained rare earth oxide in rare-earth salts and the burning back cigarette ash in tobacco leaf or the pipe tobacco, identical through the two the total amount of rare earth of converting; Can think that as a kind of proper explanations no matter rare earth still be that oxide occurs with inorganic salts, organic salt before the burning, what finally landing Jiaozhuo was used is rare earth oxide.
Harmful substance in the cigarette smoke also has a lot, for example nitrosamine, carbon monoxide, nitric oxide, and harmful substance comprises that tar all is that cigarette produces because of imperfect combustion.Catalyst has improved the condition of burning, makes cigarette burning more complete, thereby has reduced the generation of tar, can reduce the generation of nitrosamine, nitric oxide, carbon monoxide equally.Because the cigarette industry policy is more to the concern of tar, the present invention focuses on the contrast verification that reduces tar, and the present invention has data to show that rare earth compound has the effect of reduction to the nitrosamine in the cigarette smoke, carbon monoxide.
The data of collection of the present invention are gone through the several years, and the standard that detects tar has several, but the standard of the contrast between each experimental data is unified, and YC/T29-1996 is specifically arranged; ISO-4387; Cigarette is smoked panel test mark by the current cigarette of the cigarette industry standard of smokeing panel test, and is specially:
Fragrance full marks 30 minutes: foot 30, still foot 25 has 20, and few 10, flat 10;
Jealous full marks 25 minutes: pure 25, still pure 20, peppery 10, pained 5;
Assorted gas full marks 15 minutes: do not have 15, little have 12, has 10, weighs 8, weighs 6;
Excitant full marks 10 minutes: light by 10, little have 8, has 6, weighs 4, weighs 2;
Strength full marks 10 minutes: moderate 10, bigger or less 8, big or little 6;
Flammability full marks 5 minutes: strong by 5, medium 3, flame-out 0;
Ash content full marks 5 minutes: white 5, greyish white 3, black 1.
The invention has the advantages that: the rare earth oxide that utilizes rare earth compound when the cigarette high-temp combustion, to decompose, improve the condition of cigarette burning, make cigarette burning more complete, reduce the generation of tar and other harmful substances.Characteristic according to catalyst, catalyst just changes the activation energy of combustion reaction, catalyst itself does not participate in complicated combustion reaction, so the influence to the flue gas of cigarette is very little, by the current cigarette of the cigarette industry standard of smokeing panel test, compare with the blank cigarette that does not add catalyst, the positive negative variation of the mark of smokeing panel test is within 3 minutes, and most fluctuations are within 1 minute.The contrast of smokeing panel test has selected the cigarette of cigar mill of family product surplus in the of in all parts of the country ten to finish, and catalyst has shown superior adaptability and broad spectrum activity on the suction flavor.This broad spectrum activity to a certain extent even surpassed some flavouring essence for tobacco.
The present invention has added rare earth compound in tobacco leaf or pipe tobacco after, behind cigarette burning, rare earth compound finally is converted into the oxide of rare earth in combustion process, because the cigarette burning temperature also can not surpass the decomposition temperature of the oxide of rare earth in the high-temperature region, rare earth element can not fly away in flue gas with the form of metallic vapour; And finally stay in the cigarette ash behind the cigarette burning with the form of rare earth oxide.The temperature that the various inorganic salts of rare earth, organic salt are decomposed into rare earth oxide is generally at 700-880 degree centigrade, and the cigarette burning temperature can reach 900 degrees centigrade in the high-temperature region temperature, enough is decomposed into rare earth oxide.
Rare earth oxide in tobacco leaf or pipe tobacco, the cigarette ash can detect, and first preparation rare-earth chloride solution standard specimen accurately takes by weighing purity and is 99.8% mixed rare-earth oxide and adds dissolving with hydrochloric acid, the rare-earth chloride solution standard specimen is stand-by.The testing staff of cigarette industry only need collect tobacco leaf or pipe tobacco, cigarette ash, with tobacco leaf or pipe tobacco, cigarette ash is placed in the high temperature furnace with the porcelain crucible splendid attire, burnt 50 minutes at 350-400 degree centigrade, being warming up to 500 degrees centigrade again burnt 20 minutes, taking out porcelain crucible takes advantage of heat to add hydrochloric acid with rare earth oxide, or other forms of rare earth compound is all with the form stripping of rare earth-iron-boron, and separate with all the other residues, with the rare-earth chlorination matter sample, add conventional rare earth developer, and be that blank is done the colour developing working curve with the rare-earth chloride solution standard specimen, can be very easy measure the rare earth compound that adds in the cigarette.
The present invention it is to be noted that effectively reducing tar in actual production is very complicated system works, reduces the whole scientific research strength that tar need be integrated domestic cigarette industry, and just can walk unhurriedly makes bits of progress.
" tobacco science and technology " is the technical magazine of the cigarette industry sponsored of State Tobacco Monopoly Bureau, wherein has a lot of articles to set forth complexity and the difficulty that reduces tar from various angles.We think present domestic flue-cured tobacco reach the 12-15 milligram/the time, approached existing tradition and fallen the burnt limit, further effectively fall burnt and resolve simultaneously and inhale the flavor problem and need the new burnt method of falling, the invention provides the new burnt possibility of falling.
The present invention has explained that rare earth compound reduces the preliminary theoretical question of tar.The present invention sums up out on the basis of a large amount of experimental datas, verified that rare earth compound reduces the effect of tar, and by adding variety classes, the rare earth compound of varying number and the various combinations between them, comprise rare earth oxide, the rare earth inorganic matter, the rare earth organic matter, we find to have the effect of reduction tar in various degree, by analyzing the composition in the cigarette ash, show that most rare earth compounds finally all remain in the cigarette ash with the form of rare earth oxide, we have appended the reduction tar experiment of rare earth oxide again, no matter proof still is the form of oxide with the form of salt, all have and fall burnt effect, the result shows that catalytic effect shows by the rare earth oxide form.This and catalytic field catalyst coincide based on the situation of oxide mostly, but the source of rare earth oxide can various rare-earth salts and cigarette burning after produce, Here it is rare earth carbonate, rare earth monobasic, dicarboxylate, the rare earth hydroxycarboxylate, butene dioic acid rare-earth salts, beta-diketon class rare-earth salts, various combinations between RE phosphate etc. and rare earth oxide and the various rare earth compound, the general character contact that can reduce tar and reduce other harmful substances.
The present invention in tobacco leaf or pipe tobacco, is used to reduce coke tar in cigarette with the rare earth compound first Application.Find to have the catalyst of other kinds to use to chew report in the rod by retrieving us with cigarette, but catalyst in chewing rod without burning, do not form the process of oxide, different fully with the principle of the invention.
We notice that the reduction tar of external cigarette industry seldom uses chemical method, more there is not rare earth compound to reduce the report of tar, one of reason here is: external cigarette is based on the mixed type cigarette, flue-cured tobacco only accounts for a part in the mixed type cigarette, remaining component comprises spices type tobacco leaf etc., the Virginian-type cigarette of its tobacco leaf compositing formula and cigarette odor-absorbing and domestic main flow has very big difference, the suction flavor loss of using conventional physical to fall defocused flue-cured tobacco part can be adjusted by the composition that changes other Turkish tobaccos, therefore the external cigarette that mixes props up at 10mg/ and followingly can both keep suitable cigarette odor-absorbing, and this is that present domestic flue-cured tobacco is beyond one's reach.The invention provides the new purposes of rare earth compound, reduce tar for domestic flue-cured tobacco new approach is provided, certain meaning is arranged.
Owing to fall the complexity of burnt work, other the problem that needs among Jiao to solve is fallen, for example how effectively on production line, to add rare earth oxide in the tobacco leaf; How better to solve the evenly effective technical problem that absorbs rare-earth salts of tobacco leaf in the production line, can form new patent.But the enforcement of the technology that these are new all depends on the present invention, and the present invention is that rare earth compound is applied to reduce tar as the basic patent that burnt field falls in chemical catalysis, has established certain basis.
We notice that the nano material in many fields has small-size effect, quantum size effect, many peculiar, excellent performances such as skin effect and macro quanta tunnel effect.The present invention makes nanometer product with rare earth oxide and rare-earth salts, add in tobacco leaf or the pipe tobacco, burnt effect falls in discovery does not have the obviously trend of enhancing, but tobacco leaf is better to the assimilation effect of nano rare earth compound, tobacco leaf shortens the uniform absorption required time of nano rare earth compound under the similarity condition, and this is helpful to industrial applications.
Advantage of the present invention has briefly provided the new purposes of rare earth compound, and the rare-earth additive of harmful substance in a kind of new reduction cigarette smoke particularly is provided.
