中文摘要 | 摘要 本研究選用竹山地區三至五年生竹齡之 孟宗竹(Phyllostachys pubescens Mazel, Moso bamboo)為原料,於400℃、600℃及 800℃等不同溫度進行炭化,探討孟宗竹炭之 炭收率、收縮率、灰分、酸鹼值、真密度、 電阻係數、微量元素、BET 比表面積 (Brunamer-Emmett-Teller's specific area ) 及Langmuir 表面積等性質。結果顯示竹炭 之炭收率(37.10~25.30%) 及電阻係數 (3.5×1012~8×10-2 Ω‧cm),皆隨著炭化溫度之 提高而有降低之趨勢;灰分、酸鹼值(7.90 ~ 8.80)、真密度(1.36 ~ 2.28 g cm-3)及長度、厚 度收縮率則隨之增加,竹炭之BET 比表面積 與Langmuir 表面積於炭化溫度600℃可獲最 大值4.45m2 g-1、183.39 m2 g-1,顯示有較佳 孔隙性質及吸附能力。 |
英文摘要 | ABSTRACT The bamboo materials for charcoalization were selected from 3 to 5 years old Moso bamboo (Phyllostachys pubescens Mazel) in Chu-Shan area. Charcoalization was prepared at 400℃, 600℃, and 800℃, and the charcoal was analyzed for its physical and chemical properties, including charcoal recovering rate, shrinkage ratio, ash content, pH, true density, resistivity, trace element, BET’s (Brunaner-Emmett-Teller) specific area and Langmuir’s surface area. Results showed that both charcoal recovering rate (37.10~25.30%) and resistivity (3.5×1012 ~ 8×10-2 Ω‧cm) decreased with increasing charcoalization temperature, but ash content, pH (7.90 ~ 8.80), true density (1.36 ~ 2.28 g cm-3), and length and thickness shrinkage ratios increased with increasing charcoalization temperature. The BET’s specific area and Langmuir’s surface area of 600℃ bamboo charcoal temperature can obtain maximum value to 4.45 m2 g-1 and 183.39 m2 g-1, respectively, indicating better pore property and absorbed ability. |
