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(3.5×10^12~8×10^(-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4.45平方公尺g^(-1)、183.39平方公尺g^(-1)，顯示有較佳孔隙性質及吸附能力。

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 (3.5×10^12~8×10^(-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 m^2 g^(-1) and 183.39 m^2 g^(-1), respectively, indicating better pore property and absorbed ability.
