[Technical field to which the invention belongs] The present invention relates to a method for manufacturing an adsorption material. In particular, it relates to a manufacturing method and a product thereof using bamboo as a base material for manufacturing an adsorption material. [Previous Technology] With the rapid development of industry, the degree of harm to the environment caused by waste and pollutants produced by it has increased. The Environmental Protection Agency has issued and implemented the "Volatile Organic Compounds (VOCs) Air Pollution Control and Emission Standards" on February 5, 1986 to restrict and manage the emissions of volatile organic compounds in each business entity. Due to the different types of industries, the types of volatile organic compounds are also diverse and difficult to handle. Common volatile organic compounds include hydrocarbons and carbohydrate compounds containing oxygen, nitrogen, sulfur, and carbon, such as mercaptans, carbon tetrachloride, dimethyl sulfur, and so on. At present, the most common method is to remove volatile organic compounds (VOCs) in waste water and exhaust gas by using adsorbents. The reason why the adsorption material has the adsorption ability comes from the affinity of the surface of the adsorption material to the foreign adsorbate molecules. Bonding mode can be divided into physical adsorption, chemisorption and catalyst action. The most important feature of the adsorption method is that it can almost completely remove a certain component of the gas stream within the operating range in accordance with economic conditions until the capacity of the adsorbent reaches saturation, so its control efficiency is excellent. Common types of adsorbent materials are: Fuller, s Earth and Activated Clays, Alumina substrate material (Aluminum D continuation page (when the invention description page is insufficient, please note and use the continuation page)- 4- 200412253 Inventions continued
Oxide Base Materials)、矽膠凝體（smca Gai)、離子交換材 料（Ion Exchangers)、氧化鎂（苦土）基材材料（Magnesia Base Materials)以及活性碳(Activated Carb〇n)等。其中由於活性 碳具有經濟效益高、操作容易及可回收再利用等條件，廣 5义運用於廢氣、廢水處理上，且在高級污染防治技術上， 對於含有有機物或有毒物質，譬如：色素、臭氣物質、農 藥、芳香族及其他雜環類有機物，均可藉由活性碳的表面 吸附作用而去除之。因此，活性碳為目前工業界最廣泛被 使用的吸附材料。 1〇 活性碳是一種多孔隙的固體(porous solid)，活性碳的 基本性質，對其吸附能力的影響非常巨大。這些基本性質， 包括了比表面積（specific surface area)、孔隙容積（pore volume)與孔隙大小分佈（p〇re size distribution)。高比表面 積與高孔隙容積可提供大量的吸附活位：孔隙大小分佈 15 中’擁有適當的中孔可以降低吸附質（adsorbate)的傳阻力， 使得被吸附質容易進入微孔隙，提高吸附速率與吸附量。 因此’活性碳的表面孔隙結構對於吸附行為將有直接的影 響。商業級的活性碳產品最重要的特性是具有高比表面 積、高孔隙容積，所以提供相當大的吸附能力。 2〇 製造的程序固然是影響活性碳表面結構的重要因素之 一’然’原料的選擇是具有影響力的重要因素。 用以製造活性碳的原料一般是以木材（木碳、木屑）、 椰殼以及煤炭居多，此外亦有利用石化原料或廢輪胎、廢 塑料等為製造活性碳的原料。由於原料本身的特性，使各 -5- 200412253 發明說明續頁 種原料所製作出的活性碳，其所具有之吸附能力亦有所差 異。 活性碳的缺點是要定期再生、更換活性碳。再者，活 性碳的來源，又多從國外進口，不但增加了企業成本，也 5 減低的企業採用的意願。因此，尋求一種於國内即可製造 且具有優異之吸附能力之活性竣，即為目前產、學界所共 同努力之方向。Oxide Base Materials), silicone gels (smca Gai), ion exchange materials (Ion Exchangers), magnesia (bitter earth) substrate materials (Magnesia Base Materials), and activated carbon (Activated Carbon). Among them, activated carbon has the advantages of high economic benefits, easy operation, and recyclability. It is widely used in waste gas and wastewater treatment, and in advanced pollution prevention technologies, it contains organic or toxic substances such as pigments and odor Gases, pesticides, aromatics, and other heterocyclic organics can be removed by surface adsorption of activated carbon. Therefore, activated carbon is currently the most widely used adsorption material in the industry. 10 Activated carbon is a porous solid. The basic properties of activated carbon have a huge impact on its adsorption capacity. These basic properties include specific surface area, pore volume, and por size distribution. The high specific surface area and high pore volume can provide a large number of adsorption sites: the pore size distribution in 15 has the appropriate mesopores to reduce the transmission resistance of the adsorbate, allowing the adsorbed substance to easily enter the micropores, increasing the adsorption rate and Adsorption capacity. Therefore, the surface pore structure of the 'activated carbon' will have a direct influence on the adsorption behavior. The most important characteristics of commercial grade activated carbon products are high specific surface area and high pore volume, so they provide considerable adsorption capacity. 20 The manufacturing process is certainly one of the important factors affecting the surface structure of activated carbon. The raw materials used to make activated carbon are generally wood (wood charcoal, wood chips), coconut husks, and coal. In addition, there are also petrochemical raw materials, waste tires, and waste plastics as raw materials for active carbon. Due to the characteristics of the raw materials, each of the activated carbons produced by various raw materials has a different adsorption capacity. The disadvantage of activated carbon is that it must be periodically regenerated and replaced. Furthermore, the sources of activated carbon are mostly imported from abroad, which not only increases the cost of the company, but also reduces the willingness of the company to adopt it. Therefore, it is the direction of the joint efforts of the industry and academia to seek an activity that can be manufactured in China and has excellent adsorption capacity.

本發明實施例是將竹子基材送進一加熱爐内，該加熱 爐首先進行抽真空之動作，接著灌入惰性氣體（例如：氮 氣或水蒸氣等），爐内惰性氣體的壓力必須為正壓之狀態， 亦即，爐内惰性氣體的壓力必須高於外界之大氣壓力，以 5 避免外界空氣進入加熱爐内。加熱溫度，因所採用的竹子 的品種而有所不同，大約在500°C〜850°C之間。經發明人 實驗之結果，碳化步騾的加熱溫度以700°C左右，而加熱 時間大約為3 6小時左右為最佳。碳化加熱的速率大概在 每分鐘2°C〜5°C左右。當碳化完成後，應將材料冷卻至最-10 高加熱溫度的1/4至1/5之間，亦即，可降溫至100°C〜250 °C之間，最佳的溫度在200°C左右。 經過碳化的竹子基材，其重量會減輕（其是由於其中 的水分、氣體、焦油等已在加熱的過程中釋出），且竹子 内部已有些細之孔隙（pores)出現。 15 加熱完畢後，將碳化的竹子基材取出，此時，需再經 過篩選，將灰份、雜質等不需要的物質去除。 3.活化（activation)步驟： 經過碳化處理後的竹子基材，由於細孔度不足，僅有 基本的孔洞形成，因此需要再經過活化程序才能增加比表 20 面積、孔隙容積和表面官能基，藉以提高吸附能力。活化 步驟可打開封閉的微孔，並使微孔的擴張以及孔壁互相穿 通。 本發明實施例中之活化步驟是將碳化後之竹子基材經 混合預定之活化劑，例如：水蒸氣、二氧化碳、空氣等氣 -8- 200412253 發明說明續頁 體或其混合物等，再加熱至830°C〜1050°C左右，最佳為 加熱至950°C左右，時間為56小時左右。加熱的速率大 概在每分鐘3°C〜7°C左右，而當加熱至最高溫度後停留1〜3 小時。 5 當活化發生時，焦油的沉殿物（disorganized carbon)首 先會被去除，使竹子基材内之孔容積和孔表面積的產生。 接著，孔隙度就隨著活化程度逐漸增加，孔的寬度也會逐 漸力口大。 活化後之竹子基材由於活化劑的不同，即形成了 一種. 10 帶有不同表面官能基的吸附材料。 4.改質步騾： 吸附材料進行改質的步驟是為使吸附材料可吸收不同 的吸附質。其方法有將吸附材料之酸鹼值改變、將吸附材 料含浸（impregnated)於特殊的化學溶液中，另有些吸附材 15 料可被沉置於稀有金屬而充當觸媒等方式，而使吸附材料 發生改質的現象，藉以符合使用場合中所出現的吸附質特 性。 依據本製造方法所製造出的吸附材料可為粉末狀、顆 粒狀或為塊體。 20 在經過前述的碳化以及活化步驟後的竹基材料，會出 現些許經燒結後不成型的部份，如飛灰、殘屑等，因此在 碳化步驟與活化步驟完成後均分別必須加入篩選之步驟， 將前述不需要的部份移除。實際上，這些飛灰、殘屑是可 以再利用的。為達到原料100%的完全利用，可將經篩選 -9- 200412253 發明說明續寅 後之飛灰、殘屑等不成型的邵分加以收集，並經預定方式 將其再次成型，例如：將飛灰、殘屑經過粉碎，使其呈均 勻之粉末狀，然後經擠壓成型為塊狀或是顆粒狀。而後再 次經過碳化、活化步驟，或是僅進行活化步驟，使其成為 5 預定形狀之吸附材料。 經過以上私序所製備之吸附材料可應用於氣相吸附、 液相吸附以及某些特殊場合之應用。 10 15 所謂氣相吸附主要是針對吸附大氣中之揮發性有機物 (VOCs)，例如：甲醛、丙酮、正丁烷等，液相吸附則是針 對水中人體賀爾蒙干擾物質、細菌（載銀）與毒性物質（如 氯、三氯甲烷）等進行吸附以達淨化水質的效果，另外對 於液體之脫色方面亦具有顯著的效果。而特殊吸附則是經 可述《改質步驟後之吸附材料，而對特定的毒性物質、酵 素等進行物理吸附或是化學吸附動作。另外，本發明之吸 附材料對於除濕、除臭等方面，亦具有顯著的吸附效果。 20 t于的主要成分為纖維素C6Hig〇5、半纖維素與木質 素。而其橫斷面的結構，由外而内，可大致分為：表皮細 胞（竹青）、基本組織（薄壁細胞）、纖管束以及内皮（竹黃）等。 請參閱第二κ至第五w所示，t竹子經過碳化、活化等程 序後’包含竹青（第二圖）、纖管束（第三圖）、竹黃（第四圖） 以及基本組_五圖）均遍佈著直徑在lnm ::崎…另外更請參閱第六圖，其係基本組織 的、..田胞排列及細胞破裂内部空孔結構的微細構造圖，五人 可發現’在破裂的細胞(5)内部，更具有為數眾多的：隙 ~10- 200412253 發明說明Μ頁 (6)，分布於細胞壁上。因此可證明依據本製法所製造出來 之成品具有高比表面積、高孔隙容積等性質，因此可提供 優越的吸附能力。 根據顯微照片顯示，本發明之以竹子為基材所製造出 5 之吸附材料，其中大部分的孔隙直徑大概是在1 nm至數 十個nm之間，亦即，大多的孔隙是屬於IUPAC(國際理 論與應用化學聯合會）定義之中孔（mesopore)或微孔 (micropore)。因此，本發明之吸附材料對於中小分子的吸 附質的吸附能力具有優越的表現。另外，經測量，本發明 10 之吸附材料之比表面積（BET N2法）大約為1100m2/g，比一 般活性碳的比表面積（900〜1000m2/g)高出大約10%左右。 在脫色能力上，經實驗結果，對於亞甲基藍（methylene blue, —韻:適用於製作牛仔褲的染劑）的吸附能力，一淑:的 活性碳每一公克可吸附200〜250mg的亞甲基藍，而本發 15 明之吸附材料每一公克大約可吸附300 mg以上的亞甲基 藍。由此可證明，本發明之吸附材料其可提供的吸附能力 比一般的活性碳大約高出20%左右。 本創作之最主要特徵在於利用一種新穎的原料一竹 子，以作為製作吸附材料的原料，藉由竹子材料本身即具 20 有多孔性的特徵，且形成吸附材料後，其孔隙的孔徑大多 為IUPAC(國際理論與應用化學聯合會）定義之中孔 (mesopore)或微孔（micropore)之特性，以形成一種具有高 比表面積、高孔隙容積及表面官能基等性質的吸附材料， 藉以提供優越的吸附能力。 -11- 丄 2253 發明說明續頁 【圖式簡單說明】 f—圖係本發明—較佳實施例之製程流程圖； 第二圖係本發明較佳實施例所製造出之半成品吸附材 千，在竹青部分組織之放大圖； 5 帛三圖係本發明較佳實施例所製造出之半成品吸附材 料，在纖管束部分組織之放大圖； 第四圖係本發明較佳實施例所製造出之半成品吸附材 料，在竹黃部分組織之放大圖； ι 第五圖係本發明較佳實施例所製造出之半成品吸附材. 〇料，在基本組織部分組織之放大圖，以及 第六圖係本發明較佳實施例所製造出之半成品吸附材 料’顯示基本組織的細胞排列及細胞破裂内部空孔結構。 【圖式符號說明】 1，2, 3，4孔隙 5細胞 6孔隙 -12-In the embodiment of the present invention, the bamboo substrate is sent into a heating furnace. The heating furnace first performs a vacuuming operation, and then is filled with an inert gas (such as nitrogen or water vapor). The pressure state, that is, the pressure of the inert gas in the furnace must be higher than the atmospheric pressure of the outside, so as to prevent outside air from entering the heating furnace. The heating temperature varies with the type of bamboo used, and is approximately between 500 ° C and 850 ° C. As a result of experiments conducted by the inventors, the heating temperature of the carbonized step is about 700 ° C, and the heating time is preferably about 36 hours. The rate of carbonization heating is about 2 ° C ~ 5 ° C per minute. After the carbonization is completed, the material should be cooled to between 1/4 and 1/5 of the highest heating temperature, that is, it can be cooled to 100 ° C ~ 250 ° C, and the optimal temperature is 200 ° C around. The carbonized bamboo substrate will reduce its weight (because the moisture, gas, tar, etc. in it have been released during heating), and some fine pores have appeared inside the bamboo. 15 After heating, remove the carbonized bamboo substrate. At this time, you need to go through screening to remove ash, impurities and other unwanted substances. 3. Activation (activation) step: After the carbonization treatment of the bamboo substrate, due to insufficient pores, only basic pores are formed. Therefore, it is necessary to go through the activation procedure to increase the area, pore volume and surface functional groups of Table 20. To improve the adsorption capacity. The activation step opens the closed micropores and allows the micropores to expand and the pore walls to pass through each other. The activation step in the embodiment of the present invention is to mix the carbonized bamboo substrate with a predetermined activator, such as: water vapor, carbon dioxide, air and other gases. 8-200412253 Description of the invention Sequel or its mixture, etc., and then heated to 830 ° C ~ 1050 ° C, the best time is about 950 ° C, the time is about 56 hours. The heating rate is about 3 ° C ~ 7 ° C per minute, and it stays for 1 ~ 3 hours after heating to the highest temperature. 5 When activation occurs, the disorganized carbon of the tar will be removed first, so that the pore volume and pore surface area in the bamboo substrate will be generated. Subsequently, the porosity gradually increases with the degree of activation, and the width of the pores gradually increases. Activated bamboo substrates form a kind of .10 adsorbent with different surface functional groups due to different activators. 4. Modification step 骡: The modification step of the adsorbent is to make the adsorbent absorb different adsorbents. The method includes changing the pH value of the adsorbent material, impregnating the adsorbent material in a special chemical solution, and other adsorbent materials can be sunk in a rare metal to act as a catalyst. The phenomenon of modification occurs to meet the characteristics of the adsorbent in use. The adsorbent manufactured according to this manufacturing method may be powdery, granular, or block. 20 After the carbonization and activation steps, the bamboo-based material will have some sintered parts that are not formed, such as fly ash and debris. Therefore, after the carbonization step and the activation step are completed, screening must be added. Step, remove the aforementioned unwanted parts. In fact, these fly ash and debris can be reused. In order to achieve 100% full utilization of raw materials, you can collect non-sharp points such as fly ash, debris, etc. after screening-9-200412253 Description of the Invention, and reshape them in a predetermined way, such as: The ash and residue are crushed to make it a uniform powder, and then extruded into a block or granule. Then, the carbonization, activation step, or only the activation step is performed again to make it an adsorbent of a predetermined shape. The adsorption material prepared through the above private sequence can be applied to gas phase adsorption, liquid phase adsorption, and some special occasions. 10 15 The so-called gas phase adsorption is mainly for the adsorption of volatile organic compounds (VOCs) in the atmosphere, such as formaldehyde, acetone, n-butane, etc., while the liquid phase adsorption is for human hormone interference substances and bacteria (silver-loaded) in water. Adsorption with toxic substances (such as chlorine, chloroform), etc. to achieve the effect of purifying water, and also has a significant effect on the decolorization of liquids. The special adsorption is the physical adsorption or chemical adsorption of specific toxic substances, enzymes, etc. after the modification process. In addition, the adsorption material of the present invention also has a significant adsorption effect on dehumidification and deodorization. The main components of 20 t are cellulose C6Hig05, hemicellulose and lignin. The structure of its cross section can be roughly divided into: epidermal cells (bamboo green), basic tissues (thin-walled cells), fibrillar bundles, and endothelium (bamboo yellow). Please refer to the second κ through the fifth w. After bamboo has undergone carbonization and activation procedures, it includes bamboo green (second picture), quill bundle (third picture), bamboo yellow (fourth picture), and basic group_ (Figure 5) are all over lnm :: 崎 ...

Five people can find '在Inside the ruptured cell (5), there are many more: Gap ~ 10-200412253 Description of the invention Page M (6) is distributed on the cell wall. Therefore, it can be proved that the finished product manufactured according to this manufacturing method has properties such as high specific surface area and high pore volume, and thus can provide superior adsorption capacity. According to the photomicrograph, most of the adsorbent materials manufactured by the present invention using bamboo as the substrate 5 have a pore diameter between 1 nm and tens of nm, that is, most of the pores belong to IUPAC. (International Union of Theoretical and Applied Chemistry) defines mesopore or micropore. Therefore, the adsorption material of the present invention has superior performance in the adsorption capacity of small and medium molecules. In addition, it has been measured that the specific surface area (BET N2 method) of the adsorbent material of the present invention 10 is about 1100 m2 / g, which is about 10% higher than the specific surface area of general activated carbon (900-1000 m2 / g). In terms of decolorization ability, according to the experimental results, for the adsorption capacity of methylene blue (rhythm: a dye suitable for making jeans), Yishu: Each gram of activated carbon can adsorb 200 ~ 250mg of methylene blue, and the hair 15 Each gram of adsorbent material can adsorb more than 300 mg of methylene blue. It can be proved that the adsorption capacity provided by the adsorption material of the present invention is about 20% higher than that of ordinary activated carbon. The main feature of this creation is the use of a novel raw material, bamboo, as a raw material for the production of adsorption materials. The bamboo material itself has 20 characteristics of porosity, and after the formation of the adsorption material, the pores are mostly IUPAC. (International Federation of Theoretical and Applied Chemistry) defines the characteristics of mesopores or micropores to form an adsorbent material with high specific surface area, high pore volume, and surface functional groups to provide superior Adsorption capacity. -11- 丄 2253 Description of the Invention Continued [Simplified illustration of the drawing] f—The diagram is the process flow chart of the present invention—the preferred embodiment; The second diagram is the semi-finished adsorbent material manufactured by the preferred embodiment of the present invention The enlarged view of the structure in the bamboo green part; 5 and 3 are enlarged views of the semi-finished product adsorption material manufactured in the preferred embodiment of the present invention, and the structure of the fiber tube bundle part; the fourth diagram is produced in the preferred embodiment of the present invention The enlarged view of the semi-finished adsorbent material in the bamboo yellow part; ι The fifth figure is a semi-finished adsorbent material manufactured in the preferred embodiment of the present invention.
