中文摘要 | 本研究之主要目的為選用產自南投竹山之4-6 年生孟宗竹(Phyllostachys pubescens)原料,探討多階段炭化製程對竹炭液相吸附能力之效應。竹炭製造區分為一階段、二階段及三階段炭化,炭化溫度分別為400-800℃、500-900℃ 及1000℃。研究結果顯示,在液相吸附方面,本研究研製之15 種竹炭試體,除F-400(以400oC 進行一階段炭化之竹炭)者外,餘14 種碘值皆可達600 mg/g 以上,屬於活性碳等級,其中又以三階段炭化之竹炭的碘值最高,皆高於900 mg/g,甚至可達1000 mg/g 以上。就竹炭降低c 化學需氧量(COD)之效果,則顯示COD 的降低率會隨炭化次數增加而提高,此與碘值之變化趨勢一致,以三階段炭化竹炭的處理效果最佳,COD 降低率最高可達54%。 |
英文摘要 | The main objective of this study was to choose 4-6 years old Moso bamboo (Phyllostachys pubescens) from Nantou countyas raw materials, and to explore the effect of the multi-stage carbonization process on adsorption capacity of the Moso bamboo charcoal. The charcoal manufacturing process is divided into one stage, two-stage and three-stage ,and the carbonization temperatures were 400-800℃, 500-900℃ and 1000℃ respectively. The results showed that in the liquid phase adsorption, this study tested 15 bamboo charcoal specimens, besides F-400 (carbonization of 400℃ bamboo charcoal), the other 14 specimens had iodine number higher than 600 mg/g activated carbon grade, among the highest iodine number of bamboo charcoal obtained from the three stages carbonization, higher than 900 mg/g, and even up to 1000 mg/g or more. COD reduction effect on the charcoal, it showed the COD reduction rate will increase with increasing stages of carbonization, this result is consistent with the iodine value changes, and the effect of three-stage carbonized bamboo charcoal is the best, with COD reduction rate of up to 54%. |
