Description
本発明は、石炭とバイオマスを混合した燃料におけるバイオマス含有率の推定システム、及び、バイオマス含有率の推定方法に関する。 The present invention relates to a system for estimating the biomass content in a fuel in which coal and biomass are mixed, and a method for estimating the biomass content.
例えば、発電所や製鉄所では、ボイラーの燃料として石炭が多く使用されている。石炭を燃焼させた場合、排気ガスにはＣＯ２が含まれるのが現状である。このため、ボイラーの燃料として、再生可能な生物由来有機物であるバイオマス（例えば、木質や草木等の植物バイオマスや、食品残渣等の廃棄物系バイオマス、藻類等の海洋バイオマス）を混焼させる技術が注目されている（例えば、特許文献１）。ボイラーの燃料としてバイオマスを混焼させることで、化石資源由来のＣＯ２の排出量を削減することが可能になる。 For example, in power plants and steel mills, coal is often used as fuel for boilers. At present, when coal is burned, the exhaust gas contains CO 2 . For this reason, attention is focused on the technology of co-firing biomass (for example, plant biomass such as wood and plants, waste biomass such as food residue, and marine biomass such as algae), which are renewable biological organic substances, as fuel for boilers. (For example, Patent Document 1). By co-firing biomass as fuel for boilers, it is possible to reduce CO 2 emissions from fossil resources.
バイオマスは石炭に比べて一般に揮発分が多く、大きな粒子径でも燃え切り性が良好である反面、粉砕性が劣る場合がある。このため、粉砕機（ミル）の能力、ボイラーの用途や規模等に応じて石炭とバイオマスの割合を最適に設定し、燃え切り性が良い範囲の粒子径の石炭、バイオマスが混合されていることが、燃料利用としては理想と考えられている。 Biomass generally has a higher volatile content than coal, and while it has good burnout properties even with a large particle size, it may have poor grindability. For this reason, the ratio of coal and biomass is optimally set according to the capacity of the crusher (mill), the application and scale of the boiler, etc., and coal and biomass with a particle size within the range of good burnout are mixed. However, it is considered ideal for fuel utilization.
石炭とバイオマスを混合して燃料とする場合、石炭とバイオマス、及び、バイオマスの種類毎に粉砕性が相違している。このため、ミルの能力を維持するためや、例えば、ローラミルであれば、差圧上昇、ミル振幅、及び、粉砕動力の上昇等によるミルトラブルを防ぐためや、燃え切り性の良好な範囲の粒子径の石炭、バイオマスが混合された燃料を得るためには、投入される石炭原料とバイオマス原料（チップ、ペレット等）の割合だけでなく、最終的に燃料とされるまでの過程で、石炭とバイオマスの重量割合（バイオマス含有率）を把握することが重要となる。 When coal and biomass are mixed and used as fuel, the grindability differs depending on the coal and biomass and the type of biomass. Therefore, in order to maintain the capacity of the mill, for example, in the case of a roller mill, in order to prevent mill troubles due to an increase in differential pressure, a mill amplitude, and an increase in crushing power, particles in a range having good burnout properties. In order to obtain a fuel in which coal and biomass are mixed in diameter, not only the ratio of the coal raw material to be input and the biomass raw material (chips, pellets, etc.), but also the process until it is finally used as fuel is combined with coal. It is important to know the weight ratio of biomass (biomass content).

図１には一実施例に係るバイオマス含有率の推定システムの全体の構成を説明するためのブロック構成を示してある。 FIG. 1 shows a block configuration for explaining the overall configuration of the biomass content estimation system according to one embodiment.
図に示すように、燃料となる石炭が石炭供給手段１から供給ライン１ａを通して貯留手段２に供給される。また、燃料となるバイオマス（例えば、木質バイオマス、炭化バイオマス）がバイオマス供給手段３から供給ライン１ａに送られて石炭と混合され、貯留手段２に供給される。貯留手段２には、石炭とバイオマスの混合物が試料として一時的に貯留される。貯留手段２に貯留された試料は粉砕手段４（試料搬入路、粉砕機、供給路）で所定の粒径に粉砕され、微粉の燃料とされて発電手段５の燃焼手段に供給される。 As shown in the figure, coal as fuel is supplied from the coal supply means 1 to the storage means 2 through the supply line 1a. Further, biomass as fuel (for example, woody biomass or carbonized biomass) is sent from the biomass supply means 3 to the supply line 1a, mixed with coal, and supplied to the storage means 2. A mixture of coal and biomass is temporarily stored as a sample in the storage means 2. The sample stored in the storage means 2 is crushed to a predetermined particle size by the crushing means 4 (sample carry-in path, crusher, supply path), and is supplied as a fuel for fine powder to the combustion means of the power generation means 5.
尚、図に点線で示すように、バイオマス供給手段３からのバイオマスを貯留手段２に直接供給することも可能である。 As shown by the dotted line in the figure, it is also possible to directly supply the biomass from the biomass supply means 3 to the storage means 2.
粉砕手段４の試料（供給前、粉砕途中、粉砕後）の中のバイオマスの含有率を推定する含有率推定手段１０が備えられている。含有率推定手段１０は、試料に含まれる糖類の含有率（試料割合）を導出する試料割合導出手段１１と、試料割合導出手段１１で導出された試料割合が入力されると共に、バイオマスに含まれる糖類の含有率（原料割合）と、試料割合とに基づいて、試料のバイオマスの含有率を導出（推定）する制御手段１２とを有している。 The content rate estimating means 10 for estimating the biomass content in the sample (before supply, during crushing, after crushing) of the crushing means 4 is provided. In the content rate estimating means 10, the sample ratio deriving means 11 for deriving the content rate (sample ratio) of saccharides contained in the sample and the sample ratio derived by the sample ratio deriving means 11 are input and included in the biomass. It has a control means 12 for deriving (estimating) the content of biomass of a sample based on the content of saccharides (ratio of raw materials) and the ratio of samples.
尚、バイオマスに含まれる糖類の含有率（原料割合）は、予め求められて制御手段１２に記憶されている。供給されるバイオマスから原料割合をその都度導出して制御手段１２に入力することも可能である。 The content of saccharides (raw material ratio) contained in the biomass is obtained in advance and stored in the control means 12. It is also possible to derive the raw material ratio from the supplied biomass each time and input it to the control means 12.
上述したシステムでは、石炭とバイオマスが混合された試料に含まれる糖類の含有率（試料割合）が求められ、バイオマスに含まれる糖類の含有率（原料割合）が加味された状態で、試料の中の糖類の含有率（試料割合）に応じて試料のバイオマスの含有率が制御手段１２で導出される。このため、石炭には含まれず、バイオマスに含まれる糖類の含有率（原料割合）を検出することにより、石炭とバイオマスを混合した燃料（試料）におけるバイオマス含有率を導出して判断することが可能になる。 In the system described above, the content of saccharides (sample ratio) contained in the sample in which coal and biomass are mixed is obtained, and the content of saccharides contained in biomass (raw material ratio) is added to the sample. The biomass content of the sample is derived by the control means 12 according to the sugar content (sample ratio) of the sample. Therefore, by detecting the content of sugars (raw material ratio) contained in the biomass, which is not contained in coal, it is possible to derive and determine the biomass content in the fuel (sample) in which coal and biomass are mixed. become.
バイオマス（例えば、木質バイオマス、炭化バイオマス）に含まれる糖類は、グルコース、キシロース、ガラクトース、アラビノース、マンノースである。糖類の含有率（重量割合：ｗｔ.％）は、グルコース、キシロース、ガラクトース、アラビノース、マンノースの合計の重量割合（ｗｔ.％）とされる。 The saccharides contained in the biomass (for example, woody biomass, carbonized biomass) are glucose, xylose, galactose, arabinose, and mannose. The sugar content (weight ratio: wt.%) Is defined as the total weight ratio (wt.%) Of glucose, xylose, galactose, arabinose, and mannose.
例えば、グルコースがβ-１，４グリコシド結合されたものがセルロースとされる。ヘミセルロースとしては、グルコースとマンノースから構成されるグルコマンナンや、キシロースとグルクロン酸から構成されるグルクロノキシラン等を例に挙げることができる。 For example, glucose is β-1,4 glycosidic bonded to form cellulose. Examples of hemicellulose include glucomannan composed of glucose and mannose, glucuronoxylan composed of xylose and glucuronic acid, and the like.
そして、制御手段１２では、
式：（試料割合/原料割合）×１００
により前記試料のバイオマスの含有率（ｗｔ.％）が演算される（演算機能）。
つまり、バイオマスに含まれる糖類の含有率に応じて、試料に含まれる糖類の含有率が求められ、試料に含まれるバイオマスの含有率が演算される。
Then, in the control means 12,
Formula: (Sample ratio / Raw material ratio) x 100
Calculates the biomass content (wt.%) Of the sample (calculation function).
That is, the content of saccharides contained in the sample is obtained according to the content of saccharides contained in the biomass, and the content of the biomass contained in the sample is calculated.
試料に含まれるバイオマスの含有率が求められることで、燃え切り性を考慮した状態でバイオマスの供給量を制御（増加）することができる。また、粉砕されにくいバイオマスの含有率に応じて、粉砕手段４の能力を調整することができる。 By determining the content of biomass contained in the sample, it is possible to control (increase) the supply amount of biomass in consideration of burnout. In addition, the capacity of the crushing means 4 can be adjusted according to the content of biomass that is difficult to crush.
図２に基づいて試料割合導出手段１１の具体的な例を説明する。図２には糖類を検出するため具体例を説明するブロック図を示してある。 A specific example of the sample ratio deriving means 11 will be described with reference to FIG. FIG. 2 shows a block diagram illustrating a specific example for detecting saccharides.
図２に示したブロック構成は、図１で示した試料割合導出手段１１の一例（試料割合を検出するもの）としているが、バイオマスに含まれる糖類の含有率（原料割合）を検出する場合にも用いることが当然可能である。また、糖類を検出する構成は、図２に示した手法に限らず、他の手法を用いることも可能である。 The block configuration shown in FIG. 2 is an example of the sample ratio deriving means 11 (for detecting the sample ratio) shown in FIG. 1, but when detecting the content rate (raw material ratio) of saccharides contained in the biomass. Of course, it is also possible to use. Further, the configuration for detecting saccharides is not limited to the method shown in FIG. 2, and other methods can also be used.
図に示すように、試料が粉砕されて酸である硫酸により加水分解される（分解手段）。加水分解された溶液（分解溶液）が、必要に応じて固相中和カラムに通液されて固相中和される。尚、酸としては、硫酸の他に、塩酸、トリフルオロ酢酸を用いることができる。 As shown in the figure, the sample is pulverized and hydrolyzed by sulfuric acid, which is an acid (decomposition means). The hydrolyzed solution (decomposition solution) is passed through a solid phase neutralization column as needed to be solid phase neutralized. As the acid, hydrochloric acid and trifluoroacetic acid can be used in addition to sulfuric acid.
中和された溶液（分解溶液）が、糖類を分離する機能を有する手段である、配位子交換及びサイズ排除能を有する高速液体クロマトグラフのカラムに通液され、糖類が種類毎に分離される（分離手段）。即ち、分離の過程で通液される溶液の成分を溶出時間に応じて検出することで、通液される溶液中の糖類が時刻毎に検出されて糖類が種類毎に定量される（検出手段）。例えば、時間の経過と共に時刻毎に糖△、糖□、糖○のピークが出現し、それぞれの糖が定量される。 The neutralized solution (decomposition solution) is passed through a column of a high performance liquid chromatograph capable of ligand exchange and size exclusion, which is a means having a function of separating sugars, and sugars are separated by type. (Separation means). That is, by detecting the components of the solution to be passed through in the separation process according to the elution time, the saccharides in the solution to be passed through are detected at each time and the saccharides are quantified for each type (detection means). ). For example, with the passage of time, peaks of sugar Δ, sugar □, and sugar ○ appear at each time, and each sugar is quantified.
図３に基づいて石炭、木質バイオマス、炭化バイオマスに含まれる糖類の種類と割合の一例を説明する。 An example of the types and proportions of sugars contained in coal, woody biomass, and carbonized biomass will be described with reference to FIG.
図に示すように、石炭は、グルコース、キシロース、ガラクトース、アラビノース、マンノースは、いずれも検出されなかった。 As shown in the figure, glucose, xylose, galactose, arabinose, and mannose were not detected in coal.
木質バイオマスは、グルコースが３６.０（ｗｔ.％）、キシロースが７.０（ｗｔ.％）、ガラクトースが２.５（ｗｔ.％）、アラビノースが１.０（ｗｔ.％）、マンノースが７.５（ｗｔ.％）検出され、糖類の合計が５４.０（ｗｔ.％）となったことが検出された。 Woody biomass includes glucose 36.0 (wt.%), Xylose 7.0 (wt.%), Galactose 2.5 (wt.%), Arabinose 1.0 (wt.%), And mannose. It was detected that 7.5 (wt.%) Was detected, and the total amount of saccharides was 54.0 (wt.%).
炭化バイオマスは、グルコースが４３.５（ｗｔ.％）、キシロースが２.５（ｗｔ.％）、ガラクトースが０.５（ｗｔ.％）、アラビノースが０.２（ｗｔ.％）、マンノースが０.８（ｗｔ.％）検出され、糖類の合計が４７.５（ｗｔ.％）となったことが検出された。 Carbonized biomass is 43.5 (wt.%) For glucose, 2.5 (wt.%) For xylose, 0.5 (wt.%) For galactose, 0.2 (wt.%) For arabinose, and mannose. It was detected that 0.8 (wt.%) Was detected, and the total amount of saccharides was 47.5 (wt.%).
図３の結果から判るように、木質バイオマス、炭化バイオマスのそれぞれには、糖類であるグルコース、キシロース、ガラクトース、アラビノース、マンノースが含まれていることが確認された。そして、石炭には、糖類であるグルコース、キシロース、ガラクトース、アラビノース、マンノースが含まれていないことが確認された。 As can be seen from the results of FIG. 3, it was confirmed that each of the woody biomass and the carbonized biomass contained the saccharides glucose, xylose, galactose, arabinose, and mannose. It was confirmed that coal did not contain the sugars glucose, xylose, galactose, arabinose, and mannose.
石炭とバイオマス（木質バイオマス、炭化バイオマス）の混合物である試料に対し、石炭に含まれない、糖類であるグルコース、キシロース、ガラクトース、アラビノース、マンノースを定量することにより、木質バイオマス、炭化バイオマスのそれぞれのバイオマスを適用した場合に対して、試料の中のバイオマスの含有率を推定することができる。 By quantifying the sugars glucose, xylose, galactose, arabinose, and mannose, which are not contained in coal, for a sample that is a mixture of coal and biomass (woody biomass, carbonized biomass), each of the woody biomass and carbonized biomass It is possible to estimate the content of biomass in the sample when biomass is applied.
即ち、石炭と木質バイオマスの混合物である試料を適用した場合、試料に含まれる糖類の含有率を検出することで、試料のバイオマスの含有率を推定することができる。例えば、試料に含まれる糖類の重量割合が１０（ｗｔ.％）であったとすると、前述した式：（試料割合/原料割合）×１００により、
試料のバイオマスの含有率は、
１０（ｗｔ.％）/５４（ｗｔ.％）×１００＝１８．５（ｗｔ.％）
と推定される。
That is, when a sample that is a mixture of coal and woody biomass is applied, the biomass content of the sample can be estimated by detecting the content of saccharides contained in the sample. For example, assuming that the weight ratio of saccharides contained in the sample is 10 (wt.%), The above formula: (sample ratio / raw material ratio) × 100
The biomass content of the sample is
10 (wt.%) / 54 (wt.%) × 100 = 18.5 (wt.%)
It is estimated to be.
また、石炭と炭化バイオマスの混合物である試料を適用した場合、試料に含まれる糖類の重量割合を検出することで、試料のバイオマスの含有率を推定することができる。例えば、試料に含まれる糖類の重量割合が１０（ｗｔ.％）であったとすると、前述した式：（試料割合/原料割合）×１００により、
試料のバイオマスの含有率は、
１０（ｗｔ.％）/４７．５（ｗｔ.％）×１００＝２１．０（ｗｔ.％）
と推定される。
Further, when a sample which is a mixture of coal and carbonized biomass is applied, the biomass content of the sample can be estimated by detecting the weight ratio of saccharides contained in the sample. For example, assuming that the weight ratio of saccharides contained in the sample is 10 (wt.%), The above formula: (sample ratio / raw material ratio) × 100
The biomass content of the sample is
10 (wt.%) /47.5 (wt.%) × 100 = 21.0 (wt.%)
It is estimated to be.
図４に基づいて石炭とバイオマスの混合物である試料の粉砕物の状況を説明する。図４には試料の粉砕物の粒径の分布を説明するグラフを示してある。 The situation of the pulverized sample which is a mixture of coal and biomass will be described with reference to FIG. FIG. 4 shows a graph explaining the distribution of the particle size of the pulverized sample.
石炭単体で十分な燃焼性を確保するためには、粒径Ｘ１（最大必要粒径：例えば７５μｍ）以下に調整する必要がある。このため、石炭単体の場合、微粉炭の粒径の分布の山は粒径Ｘ１以下の範囲に大部分が収まっている（図中点線）。 In order to ensure sufficient combustibility of coal alone, it is necessary to adjust the particle size to X1 (maximum required particle size: for example, 75 μm) or less. Therefore, in the case of coal alone, most of the peaks of the particle size distribution of pulverized coal are within the range of the particle size X1 or less (dotted line in the figure).
一方、バイオマスは石炭に比べて燃焼性が高いため、石炭の最大必要粒径Ｘ１よりも径が大きい粒径Ｘ２（Ｘ１<Ｘ２）の粒であっても、良好な燃え切り性が得られる。例えば、同じ能力のミルで試料を粉砕した場合、粉砕しにくいバイオマスが混合されることで、試料の粒径の分布の山は粒径が大きくなる側に変化する（図中太線）。 On the other hand, since biomass has higher flammability than coal, good burnout property can be obtained even with particles having a particle size X2 (X1 <X2) having a diameter larger than the maximum required particle size X1 of coal. For example, when a sample is crushed with a mill having the same capacity, the peak of the particle size distribution of the sample changes to the side where the particle size increases due to the mixing of biomass that is difficult to crush (thick line in the figure).
バイオマスの含有率が求められているため、試料を粉砕した時の石炭の分布の山（図中一点鎖線）と、試料を粉砕した時のバイオマスの分布の山（図中二点鎖線）を把握することができる。例えば、石炭に関してバイオマスを混合することで、径が大きい側に分布の山のピークがどの程度変化するか（どの程度粉砕されなくなったか）を認識することができる。 Since the biomass content is required, grasp the mountain of coal distribution when the sample is crushed (single-dot chain line in the figure) and the mountain of biomass distribution when the sample is crushed (two-dot chain line in the figure). can do. For example, by mixing biomass with coal, it is possible to recognize how much the peaks of the distributed mountains change (how much they are not crushed) on the larger diameter side.
粉砕されにくいバイオマスの混合により、最大必要粒径Ｘ１を超える粒径の石炭（燃え切り性が劣る粒径の石炭）が存在することになるが、燃えやすく燃え切り性が保たれる粒径Ｘ２以下の粒径が大部分であるバイオマスが存在していることがわかる。 Due to the mixing of biomass that is difficult to crush, coal with a particle size exceeding the maximum required particle size X1 (coal with a particle size inferior in burnout) exists, but the particle size X2 is flammable and maintains burnout. It can be seen that biomass having the following particle size is mostly present.
従って、同じ能力のミルを用いた場合であっても、石炭単体の微粉炭と同程度の燃え切り性を保つことができることがわかる。即ち、バイオマスの含有量を推定して適切に管理することで、設備を変更することなく、燃え切り性を維持した状態でバイオマスの含有率を調整すること（増加させること）が可能になる。 Therefore, it can be seen that even when mills having the same capacity are used, it is possible to maintain the same level of burnout property as pulverized coal of coal alone. That is, by estimating the biomass content and managing it appropriately, it is possible to adjust (increase) the biomass content while maintaining the burnout property without changing the equipment.
従って、大きい粒径の微粉炭が増えても（粒径の平均が高くなっても）、所定の粒径以下で燃え切り性が高い状態が維持されたバイオマスが混合されることにより、バイオマスが混合された試料（混合燃料）の燃え切り性は、所定の粒径以下の微粉炭だけの場合の燃え切り性と同程度の性能が維持される。即ち、バイオマスの含有率を管理することにより、粒径が大きい微粉炭を増やしても（ミルの能力を高くしなくても）、小さな粒径に管理した微粉炭の単体の燃料を用いた場合と同程度の燃え切り性を維持することが可能になる。 Therefore, even if the amount of pulverized coal having a large particle size increases (even if the average particle size becomes high), the biomass is mixed by mixing the biomass having a predetermined particle size or less and maintaining a high burnout property. The burnout property of the mixed sample (mixed fuel) is maintained at the same level as the burnout property when only pulverized coal having a predetermined particle size or less is used. That is, even if the pulverized coal having a large particle size is increased by controlling the biomass content (without increasing the capacity of the mill), when a single fuel of the pulverized coal controlled to have a small particle size is used. It is possible to maintain the same degree of burnout.
上述したバイオマス含有率の推定システム、及び、バイオマス含有率の推定方法によると、試料割合導出手段１１で、試料に含まれる、糖類であるグルコース、キシロース、ガラクトース、アラビノース、マンノースを定量して重量割合を把握することにより、試料に含まれるバイオマスの含有率を制御手段１２で判断することが可能になる。 According to the above-mentioned biomass content estimation system and biomass content estimation method, the sample ratio deriving means 11 quantifies glucose, xylose, galactose, arabinose, and mannose, which are sugars contained in the sample, and weight ratio. By grasping the above, the content rate of the biomass contained in the sample can be determined by the control means 12.
図５から図７に基づいて試料割合導出手段１１の他の具体的な例を説明する。図５から図７には糖類を検出するための他の具体例を説明するブロック図を示してある。 Another specific example of the sample ratio deriving means 11 will be described with reference to FIGS. 5 to 7. 5 to 7 show block diagrams illustrating other specific examples for detecting saccharides.
図５から図７に示した構成は、図２に示した構成と同様に、バイオマスに含まれる糖類の含有率（原料割合）を検出する場合にも用いることが当然可能である。 Similar to the configuration shown in FIG. 2, the configuration shown in FIGS. 5 to 7 can naturally be used when detecting the content rate (raw material ratio) of saccharides contained in the biomass.
図５に示すように、試料が粉砕されてバイオマス分解酵素剤（酵素剤）により加水分解される（分解手段）。加水分解された溶液（分解溶液）が、糖類を分解する機能を有する手段である、配位子交換及びサイズ排除能を有する高速液体クロマトグラフのカラムに通液され、糖類が種類毎に分離される（分離手段）。即ち、分離の過程で通液される溶液の成分を溶出時間に応じて検出することで、通液される溶液中の糖類が時刻毎に検出されて糖類が種類毎に定量される（検出手段）。例えば、時間の経過と共に時刻毎に糖△、糖□、糖○のピークが出現し、それぞれの糖が定量される。 As shown in FIG. 5, the sample is pulverized and hydrolyzed by a biomass-degrading enzyme agent (enzymatic agent) (decomposition means). The hydrolyzed solution (decomposition solution) is passed through a column of a high performance liquid chromatograph capable of ligand exchange and size exclusion, which is a means having a function of decomposing sugars, and sugars are separated by type. (Separation means). That is, by detecting the components of the solution to be passed through in the separation process according to the elution time, the saccharides in the solution to be passed through are detected at each time and the saccharides are quantified for each type (detection means). ). For example, with the passage of time, peaks of sugar Δ, sugar □, and sugar ○ appear at each time, and each sugar is quantified.
図６に示すように、試料が粉砕されて酸である硫酸により加水分解される（分解手段）。加水分解された溶液（分解溶液）が、必要に応じて固相中和カラムに通液されて固相中和される。尚、酸としては、硫酸の他に、塩酸、トリフルオロ酢酸を用いることができる。 As shown in FIG. 6, the sample is pulverized and hydrolyzed by sulfuric acid, which is an acid (decomposition means). The hydrolyzed solution (decomposition solution) is passed through a solid phase neutralization column as needed to be solid phase neutralized. As the acid, hydrochloric acid and trifluoroacetic acid can be used in addition to sulfuric acid.
中和された分解溶液が分けられ、分解溶液にグルコース呈色試薬（試薬Ａ）、キシロース呈色試薬（試薬Ｂ）がそれぞれ添加される。分解溶液に呈色試薬を加えることで、分解溶液に含まれる特定の糖類を呈色させて糖類が分離される（分離手段）。 The neutralized decomposition solution is separated, and a glucose coloring reagent (reagent A) and a xylose coloring reagent (reagent B) are added to the decomposition solution, respectively. By adding a coloring reagent to the decomposition solution, specific saccharides contained in the decomposition solution are colored and the saccharides are separated (separation means).
試薬Ａ、試薬Ｂがそれぞれ添加された中和分解溶液を分取し、分光光度計にセットして所定の光Ｉｏを照射する。照射した光Ｉｏの透過光Ｉｔを測定することで（呈色試薬が加えられた溶液の色を判定することで）、グルコースの含有率、キシロースの含有率を検出する（検出手段）。つまり、呈色試薬が加えられた溶液の色を判定することで、糖△、糖□、糖○の含有率が求められる。 The neutralization decomposition solution to which Reagent A and Reagent B are added is separated, set in a spectrophotometer, and irradiated with a predetermined light Io. By measuring the transmitted light It of the irradiated light Io (by determining the color of the solution to which the color-developing reagent is added), the glucose content and the xylose content are detected (detection means). That is, the contents of sugar Δ, sugar □, and sugar ○ can be obtained by determining the color of the solution to which the color-developing reagent is added.
図７に示すように、試料が粉砕されてバイオマス分解酵素剤（酵素剤）により加水分解される（分解手段）。バイオマス分解酵素剤（酵素剤）により加水分解された分解溶液が分けられ、分解溶液にグルコース呈色試薬（試薬Ａ）、キシロース呈色試薬（試薬Ｂ）がそれぞれ添加される。分解溶液に呈色試薬を加えることで、分解溶液に含まれる特定の糖類を呈色させて糖類が分離される（分離手段）。 As shown in FIG. 7, the sample is pulverized and hydrolyzed by a biomass-degrading enzyme agent (enzymatic agent) (decomposition means). The decomposition solution hydrolyzed by the biomass-degrading enzyme agent (enzyme agent) is separated, and a glucose coloring reagent (reagent A) and a xylose coloring reagent (reagent B) are added to the decomposition solution, respectively. By adding a coloring reagent to the decomposition solution, specific saccharides contained in the decomposition solution are colored and the saccharides are separated (separation means).
試薬Ａ、試薬Ｂがそれぞれ添加された分解溶液を分取し、分光光度計にセットして所定の光Ｉｏを照射する。照射した光Ｉｏの透過光Ｉｔを測定することで（呈色試薬が加えられた溶液の色を判定することで）、グルコースの含有率、キシロースの含有率を検出する（検出手段）。つまり、呈色試薬が加えられた溶液の色を判定することで、糖△、糖□、糖○の含有率が求められる。 The decomposition solutions to which Reagent A and Reagent B have been added are separated, set in a spectrophotometer, and irradiated with a predetermined light Io. By measuring the transmitted light It of the irradiated light Io (by determining the color of the solution to which the color-developing reagent is added), the glucose content and the xylose content are detected (detection means). That is, the contents of sugar Δ, sugar □, and sugar ○ can be obtained by determining the color of the solution to which the color-developing reagent is added.
