The raw material of embodiment 1 is selected
Physicochemical characteristics analysis experiment of the present invention by producing sugarcane fibre raw material with different regions carries out raw material selection.
To exempt to repeat, the present embodiment only produces bagasse and Guangxi that the bagasse of the kind of cloud sugarcane 03, Guangdong produce Guangdong 00 kind of sugar with Yunnan
The bagasse of new platform sugar ROC16 kinds is produced for raw material is illustrated.

1.2 raw materials and treatment
Bagasse Material is provided by Yunnan sugar refinery, Guangdong sugar refinery and Guangxi sugar refinery respectively, raw material mass dryness fraction about 50%；
SWBQ0010 special fibres raw material is provided by cigarette in Guangdong.Representative Bagasse Material is taken at random, is sieved with 8 mesh sieves after air-drying
Except fragment and dust, about 200 grams of sugarcane fibres are then taken using quartering, be then milled to powder, mistake with plant pulverizer
After sieve, 40~60 mesh powder are collected, be stored in equilibrium water conten in sealed plastic bag, bagasse chemical composition is analyzed for subsequent measurements
When use.
1.3 experimental results
The sugarcane fibre of the kind and the chemical constituent analysis result of SWBQ0010 special fibres are listed in the table below in 1.
As it can be seen from table 1 the content of ashes that sugarcane fibre is produced in Yunnan is 1.24%, the ash content that sugarcane fibre is produced in Guangxi contains
It is 0.75% to measure, and in three major production areas sugarcane fibres, the content of ashes highest of sugarcane fibre is produced in Yunnan.Because ash content is main
Composition is the inorganic matter such as calcium, potassium, sodium, magnesium, manganese and phosphorus, silica, needed for these elements are plant growth nutrition, potassium ion
It is relative benign to tobacco product that content is higher, and the increase of preservative water preperation can strengthen the firepower of holding of tobacco leaf, promote cigarette
Cigarette is burnt, and then reduces cigarette tar content, improves the security of cigarette.In YC/T 16.3-2003《Reconstituted tobacco the 3rd
Point：Paper process》In, also using potassium content as one of its characteristic index, therefore ash content to sugarcane fibre in reconstituted tobacco should
With not constituting negative effect.But, content of ashes especially metal ion content too high sample high, the color of ashes after burning
Obfuscation；In addition, ash content is high and can cause fiber separation subtractive process pipeline scale and cause difficulty to devil liquor recovery.Therefore, from ash
Divided by it is poor with respect to Guangxi, Guangdong product sugarcane fibre that sugarcane fibre is produced in Yunnan.
The chemical constituent of the Yunnan Province of table 1 representativeness sugarcane fibre raw material
From the point of view of the content of the big component fibre element of 1 sugarcane fibre of table three, hemicellulose and lignin, it is comprehensive that sugarcane fibre is produced in Yunnan
Cellulose, hemicellulose, the content of total lignin are respectively 70.24%, 25.56%, 19.86%, and its holocellulose content is three
Minimum among person, hemicellulose level is then highest among three, shows that the content of cellulose of sugarcane fibre is produced most in Yunnan
It is few.If using sugarcane fibre separation and purification sugarcane fibre element, yield is relatively low, and production cost is of a relatively high.Hemicellulose splits
Solution can produce irritating heat-decomposing compound (for example producing more low-grade aldehydes), and irritating choking can be caused when burning and sucking
Cough, thus the low raw material of hemicellulose level, its quality is preferable.As can be seen here, from economy point and product quality angle, cloud
Produce sugarcane fibre and produce sugarcane fibre not as good as Guangxi, Guangdong in south.In addition, as can also be seen from Table 1, the hot water of sugarcane fibre is produced in Yunnan
Extract content is that 25.62%, 1%NaOH extracts are that 40.61%, alcohol-benzene extractive content is 1.85%；Each extract
Content is above Guangdong, Guangxi and produces sugarcane fibre.These components, during cellulose is separated, the overwhelming majority can all degrade
Dissolution.The chemicals consumption of sugarcane fibre subtractive process, therefore the low original of extract content can be increased due to the presence of which
Material, quality is preferable, namely the inferior quality of sugarcane fibre is produced in Yunnan.Therefore, chemically for composition analysis result, Yunnan is produced sweet
The quality of sugarcane fiber is lower than Guangdong, Guangxi product sugarcane fibre quality.
As can also be seen from Table 1, Sugarcane in Guangdong fiber holocellulose content, hemicellulose, acid-insoluble lignin, total lignin
Content is respectively 77.20%, 23.30%, 20.27% and 21.56%, wherein the content of hemicellulose and acid-insoluble lignin, total
Lignin content (including acid soluble lignin) is above Guangxi sugarcane fibre.Hemicellulose and the low raw material of lignin content, its quality compared with
Get well, namely the quality of Sugarcane in Guangdong fiber is poor compared with Guangxi sugarcane fibre.
As can also be seen from Table 1, hot water extract's content of Sugarcane in Guangdong fiber is that 16.96%, 1%NaOH extracts are
37.02%th, alcohol-benzene extractive content is 1.35%；The content of each extract is above Guangxi sugarcane fibre.These components, are dividing
During cellulose, most dissolutions that can all degrade.Because the presence of which can increase sugarcane fibre subtractive process
Chemicals is consumed, therefore the low raw material of extract content, quality preferably, namely Sugarcane in Guangdong fiber quality compared with Guangxi sugarcane
Fiber is poor.
In sum, chemically for composition analysis result, the quality that sugarcane fibre is produced in Guangxi is produced than Guangdong and Yunnan
Sugarcane fibre quality is high.
The sugarcane fibre of embodiment 2 is plain to be refined

2. raw material and treatment
The wet feed after 100 grams of equilibrium water contens of over dry is weighed, then water or acid solution needed for being added by the process conditions of table 2 fill
Enter canister, be transferred in digester after sealing, then reacted with a temperature of in the heating curve for setting.After reaction terminates, by sugarcane
Slag and liquid are moved into 200 mesh Nylon Bags in the lump, extrude and collect waste liquid, then will hydrolyze sample washes clean, are used for analysis.
The bagasse clear water of table 2/weak acid pre-hydrolysis technique condition
Note：Heating-up time is 60~70min.
3. experimental result
3.1 hydrolysis sample chemical constituent analyses
Hydrolysis sample is processed by preceding method, the sample chemical constituent that is hydrolyzed analysis, experimental results are listed in table 3 and table 4
In.
The different hydrolysis process gained hydrolysis sample yield of table 3, pH value and ash content
Note：Absolute magnitude is actual content of the component in sample is hydrolyzed；
Relative quantity=absolute magnitude × hydrolysis yield；
Relative quantity/the component of extrusion rate=1- components content in the feed
Can be seen that sour consumption is higher from table 3 and Fig. 1, the pH of hydrolytic process is lower, hydrolysis yield is lower；Hydrolysis temperature
Higher, the pH of the hydrolytic process under the same terms is lower, hydrolysis yield is also lower.But from the point of view of comparing, difference is not very bright
It is aobvious.
From the point of view of the change of ash content, with the increase of sour consumption, ash content abjection is taken the lead in slightly increasing, and then reduces, and acidity is got over
By force, ash content extrusion rate is lower；And hydrolysis temperature abjection ratio higher is bigger.This influence of explanation temperature to ash content is greater than acid
The influence of catalysis, and acidity is stronger, the abjection to ash content is on the contrary unfavorable.
From table 4, it can be seen that in the case of other experiment condition identicals, with the increase of acid concentration, hydrolyzing sample poly- penta
The removal efficiency of sugar is significantly improved, and cellulose loss rate increases, hydrolysis yield reduction.(the experiment number 1 under conditions of not acid adding
With experiment number 4), because under high-temperature and high-pressure conditions, water can dissociate H+And OH-, destroy hemicellulose oxy-acetyl and furfural acid
Substituent, generates organic acid, and then promotes the degraded dissolution of hemicellulose by self-catalyzed reaction.But contrast experiment number 1 and reality
The number of testing 2, is hydrolyzed using anacidity self-catalysis, and experiment poly-pentose extrusion rate is low, and only 21.80%, and after the acid of addition 0.5%,
Poly-pentose extrusion rate, up to 85.25%, is the former 3.9 times in experiment；This shows that in pre-hydrolysis process acid is to hemicellulose
Dissolution serves catalytic action.Because hemicellulose molecule contains free hydroxyl group, it is a kind of polar group, with hydrophilic
Property, thus it is soluble in water.Its degree of polymerization is relatively low, and generally without crystal structure, arrangement is loose, is easily hydrolyzed under acid environment.
When being hydrolyzed using dilute sulfuric acid, the H that acid is dissociated in water+H can be combined into water3O+, glucosides in hemicellulose molecule can be made
The oxygen atom protonation of key, forms conjugate acid, and be broken because bond energy weakens.The carbonium ion of end can produce matter again after fracture
Son, proton reacts with water, generates new water and hydrogen ion, participates in new hydrolysis.Therefore, it is acid-hydrolyzed to hemicellulose
Solute effect is hydrolyzed more than self-catalysis.But the increase of acid concentration, helps little to the extrusion rate of poly-pentose, such as acid concentration from
0.5% brings up to 1.0%, and the poly-pentose extrusion rate of experiment number 3 only improves 0.66%, the poly-pentose of experiment number 6 than experiment number 2
Extrusion rate only improves 0.29% than experiment number 2.
Influence of the different hydrolysis process of table 4 to hydrolysis sample carbohydrate
In addition, as can also be seen from Table 4, in the case of other experiment condition identicals, with the raising of temperature, hydrolyzing sample
Poly-pentose removal efficiency slightly has raising, but hydrolysis yield is then significantly reduced, and holocellulose loss late is dramatically increased.Such as in temperature 155
DEG C, sulfuric acid concentration 0.5% when, poly-pentose removal efficiency be 85.52%, prehydrolysis yield, holocellulose loss late are respectively
66.09% and 36.09%.Under similarity condition, temperature lifting to 160 DEG C, hydrolysis sample poly-pentose removal efficiency improve only
3.62%, but its hydrolysis yield then have dropped 4.87%, and holocellulose loss late increased 4.71%, exceed poly-pentose
Extrusion rate.This is because under higher temperature, prehydrolysis reaction aggravates, and carbohydrate is drastically degraded, and makees in inorganic acid
Under, the activation energy reduction of glucoside bond causes cellulose dissolution rate to be accelerated.
Accompanying drawing 2 shows the relation of prehydrolysis yield and poly-pentose clearance.From accompanying drawing 2, the yield of prehydrolysis with
The increase of poly-pentose clearance and reduce.But according to the difference of its amplitude for reducing, 2 intervals can be divided into.Poly-pentose is removed
Rate is interval A 0~85%.This interval yield can use linear equation Y=98.0096- with the relation of poly-pentose removal efficiency
0.373X is represented.Herein in interval, yield declines more slow, poly-pentose removing about 85%, and yield only reduces about 25%.Poly- penta
Sugared removal efficiency is interval B 85%~90%.Herein in interval.Yield can use linear equation with the relation of poly-pentose removal efficiency
Y=176.145-1.291X represents that its slope is 3.46 times of interval A.This explanation in interval 2, prehydrolysis yield decline compared with
Hurry up, the removing of poly-pentose is extremely difficult, it is necessary to sacrifice yield as cost.Herein in interval, poly-pentose removal efficiency is not enough
4%, and yield reduces about 5%.As the above analysis, interval A slopes are smaller, are the optimum interval of pretreatment.To sum up institute
State, the preferred process condition that choice experiment 2 is processed as bagasse prehydrolysis.Now, prehydrolysis yield is 66.09%, poly-pentose
Removal efficiency is 85.25%.
Influence of the different hydrolysis process of table 5 to hydrolysis sample trees cellulose content
As can be seen from Table 5, lignin there occurs different degrees of degraded dissolution in pre-hydrolysis process.For sour insoluble wood
Element, acid stronger, temperature is higher, and the lignin of dissolution is more；For acid soluble lignin, then a large amount of dissolutions, it is left that extrusion rate reaches 50%
The right side, because whether self-catalysis or acid-catalyzed hydrolysis, the pH of pre-hydrolysis process is in acid (being shown in Table 3).

2. experimental raw and treatment
Soda cooking and D0EpD1 tri-stage bleachings are carried out to amplification test gained prehydrolysis sample, then gained slurry is entered
Row mashing, handsheet, then determine the strength character of page.
3. experimental result
3.1 hydrolysis sample soda pulping processes
Slurrying is carried out according to the technique of table 6, acquired results and characteristics of pulp are shown in Table 6 and table 6.
Influence of the base amount of table 6 to prehydrolysis sugarcane fibre pulpability
* with respect to yield=paper pulp yield × hydrolysis yield；
Other techniques：160 DEG C of temperature, intensification 60min is incubated 60min, liquor ratio 1:4.
As can be seen from Table 6, paper pulp yield is reduced with the increase of alkali charge, such as when base amount is 13% and 19%
Paper pulp yield is respectively 50.63% and 46.44%, reduces 8.28%；But 30.68% then is down to from 33.45% with respect to yield,
Reduce about 2.8%；At the same time pulp hardness (Kappa number) is then down to 10.63% from 92.21.From black liquor pH value and black liquor
From the point of view of solid content, alkali charge is crossed, and the pH value of black liquor is higher, and solid content is also higher, and this reflects that base amount is bigger,
The material of dissolution is more, and this is also the reason for yield is gradually reduced.From the point of view of pulp brightness, alkali charge is higher, and whiteness is higher.When
Alkali charge is less than 15%, and pulp brightness is no more than 30%ISO；When alkali charge reaches 17%, now pulp brightness reaches 35.5%
ISO, continues to increase base amount to 19%, and whiteness is further increased to 43.3%ISO.Beating degree has reacted the wire-dividing broom purification of slurry
Degree, as can be seen from Table 6, base amount is bigger, and the swollen of slurry, wire-dividing broom purification are more obvious, shows as the rising of beating degree.
The brown stock physical property of table 7
For paper grade pulp, tensile index is higher, paper pulp intensity is better.But for reconstituted tobacco (YC/T16.3-
2003), its tensile strength requirement is no more than 1.0kN/m.Therefore, want the ratio of paper pulp in raising reconstituted tobacco, reduce additional
The tensile strength of paper pulp is one of necessary means.From table 7 from the point of view of physical property, preprocessed repulping gained brown stock intensity
It is relatively low, by quantitative 110g/m2Calculate, between 2.75~3.30kN/m, this is very beneficial for improving the tensile strength of brown stock
Its adding proportion in reconstituted tobacco.
Accompanying drawing 3 is described without under base amount, the variation tendency of physical property of pulp.From accompanying drawing 3 as can be seen that alkali is used
Amount improves 15% from 13%, and each intensity index of paper pulp has a raising；Continue to improve base amount to 17%, each intensity index
Then it is remarkably decreased, then continues to increase base amount, each index then changes unobvious.
Comprehensive analysis, base amount is proper between 17~19%.
The bleaching characteristic of 3.2 hydrolysis sample alkaline pulps
Choose 4#Sample carries out D by following techniques0EpD1Tri-stage bleaching, gained bleached cellulose pulp characteristic is listed in Table 8 below.
Bleaching process：
D0：ClO21.0%, slurry dense 10%, temperature 60 C, time 60min；
Ep：NaOH 1.5%, H2O20.5%, slurry dense 10%, 65 DEG C of temperature, time 90min；
D1：ClO20.4%, slurry dense 10%, temperature 70 C, time 90min.
The bleached cellulose pulp characteristic of table 8
From the point of view of the characteristic of the bleached cellulose pulp of table 8, through bleaching, pulp brightness reaches 85.9%ISO, with commodity
Bleached wood pulp whiteness is close.Every intensity index of paper pulp slightly has improvement, this removal for being mainly due to fiber fines and fiber
The brooming of element.From the point of view of viscosity, bleaching viscosity has declined.From the point of view of a- content of cellulose, by pretreatment, brown stock
Slightly improved after being above 90%, and bleaching with the cellulose purity of bleached pulp.
All in all, using " acid prehydrolysis+alkalescence boiling+ECF is bleached ", can be existed with isolated a- content of cellulose
90~92% or more refined cellulose.
