中文摘要 | 本研究以石栗種殼為原料,先經500、600、700與800℃炭化處理並計算炭收率,隨後將該等石栗種殼炭分別於800與900℃下,以水蒸氣法進行活化處理,探討不同炭化溫度與活化溫度對石栗種殼炭與活性碳基本性質之影響,試驗項目包括pH值、灰分、真密度、比表面積、碘值與亞甲基藍吸附值等。試驗結果得知,未活化處理石栗種殼炭之炭收率隨炭化溫度增高而降低,而pH值與灰分則隨炭化溫度增高而增加,經活化處理後pH值與灰分明顯增加,亦隨炭化溫度增高而增加。石栗種殼炭之真密度隨炭化溫度增高而增大,其中炭化溫度500與600℃之石栗種殼炭經活化處理後,其真密度明顯增加,而炭化溫度700與800℃者之增大幅度較小。石栗種殼炭之比表面積隨炭化溫度增高而明顯增大,經活化處理後之比表面積較未活化者增加,但隨炭化溫度之增加較不明顯,900℃活化處理之比表面積較800℃者明顯增加。石栗種殼炭之碘值與亞甲基藍吸附值隨炭化溫度增高而明顯增大,且經活化處理後兩者之值明顯增大,且900℃活化處理者均較800℃者具有較佳之吸附能力。 |
英文摘要 | In this study, Aleurites moluccana (Candlenut tree) testas were used for charcoal making as raw material, carbonized at 500, 600, 700, 800 ℃ and charcoal yields were calculated. The charcoal was activated by steam at 800 and 900 ℃, respectively. The effects of carbonization temperature and activation temperature on the basic properties of charcoal and activated carbon were investigated. The tests of pH value, ash content, true density, specific surface area, iodine value and methylene blue adsorption value were carried out. The charcoal yield decreased with the increase of the carbonization temperature, while the pH and ash content increased with the increase of the carbonization temperature. After the activated treatment, the pH and ash content increased significantly, and also increased with the increase of the carbonization temperature. The true density of the charcoal increased with the increase of the carbonization temperature, and the carbonization temperature at 500 ℃ and 600 ℃ after the activated treatment of the charcoal, the true density increased significantly, while the carbonization temperature at 700 and 800 ℃ increased in the smaller scale. The specific surface area of the charcoal increased significantly with the increase of the carbonization temperature. The specific surface area of activated carbon increased with the increase of carbonization temperature, compared to the charcoal, but the increase with the carbonization temperature is less obvious. The specific surface area of 900℃ activated carbon was larger than that of 800℃.The iodine value and the adsorption value of methylene blue increased obviously with the increase of carbonization temperature. After activated treatment, the values of the adsorption increased significantly, and the 900℃ activated treatment had better adsorption capacity than that of 800℃. |
