The e'ects of re-activation on the

The e'ects of re-activation on the surface areas and pore volumes are shown in Table 1. The raw material, AC, has relatively high micropore surface area than other samples. But as the treating temperature increased, the ratio of Smi=SBET decreased gradually. In the case of AC800, microand meso surface areas as well as pore volumes were well developed, simultaneously. For the samples of AC900 and AC1000, the rapid declines of surface areas and pore volumes were observed, especially, in the micropore part. It can be thought that the pore volumes of the activated carbons increase with activation temperatures up to about 800◦C. This indicates that the pores enlarge up to this temperature. Above 800◦C, the excess enlargement causes the combination of pores, resulting in the increase of mesopores and the decrease of micropore volume and the surface area as well. The other reason is the graphitization of samples over 900◦C. In Fig. 6, the evidence of graphitization can be seen in the XRD peak shown around the 2 of 26◦. The inAuences of activation temperature on the pore volume of activated carbons are summarized in Fig. 2. This shows that thepreparedactivatedcarbonshavevariousporositieswhich were intended at the start of the present study.

結果 (繁體中文) 2:

表1顯示了在表1上重新啟動表。原料AC的微孔表面積比其他樣品高。但隨著治療溫度的升高，Smi_SBET的比例逐漸下降。在AC800中，微和中索表面積以及孔徑同時得到良好開發。對於AC900和AC1000的樣品，觀察到表面積和孔隙體積的快速下降，特別是在微孔部分。可以認為，活性炭的孔隙體積隨著活化溫度高達800°C而增加。這表明孔隙放大到這個溫度。在800°C以上，過度膨脹導致孔隙組合，導致中孔增加，微孔體積和表面積減少。另一個原因是900°C以上的樣品的石墨化。在圖6中，在26°的2附近顯示的XRD峰值中可以看到石墨化的證據。圖2總結了活性炭孔隙體積活化溫度的失調。這表明，本研究開始時所準備的活性炭具有各種類型。

錶1顯示了表面積和孔隙體積上的再活化係數。原料AC的微孔比表面積比其它樣品高。但隨著處理溫度的升高，Smi=SBET的比值逐漸降低。在AC800的情况下，微-細觀表面積和孔隙體積同時發育。對於AC900和AC1000樣品，其比表面積和孔體積均呈快速下降趨勢，特別是微孔部分。可以認為，活性炭的孔體積隨著活化溫度的升高而增大，最高可達800℃左右，這表明在該溫度下，活性炭的孔體積增大。在800℃以上，過大的膨脹導致孔隙的結合，導致介孔增大，微孔體積和比表面積减小。另一個原因是樣品的石墨化溫度超過900°C。在圖6中，26°2附近的XRD峰顯示石墨化迹象。活化溫度對活性炭孔體積的影響如圖2所示。這表明，在本研究開始時，預活化碳具有不同的孔隙率。
