Abstract:	本研究探討借物理活化法,以清潔生產技術方式將國內大宗農業廢棄物玉米穗軸轉化為活性探之可行性。實驗過程中以不同之玉米顆粒大小、熱烈解溫度、停留時間、活化氣體等重要操作條件,製成活性碳,並分析其物理及化學特性。研究結果顯示:玉米穗軸破碎至12-16mesh、活化氣體為二氧化碳、熱烈解溫度900.degree.C及其停留時間80分鐘之下,製得比表面積高達1,705m/sup 2//g之活性碳。故以二氧化碳物理活化法,將玉米穗軸農業廢棄物轉成微孔性活性碳是可行的。 This research was to investigate the feasibility of using clean production technology for converting the domestic agrowaste corn cob into the activated carbon using physical activation methods. Important process parameters (i.e. pyrolysis temperature, activation gases, soaking time, and size of particle etc.) were evaluated to examine the chemical/physical characterization of the resulting activated carbons. The experimental results show that the optimal conditions for the production of microporous activated carbon with high BET surface area (e.g. 1,705m/sup 2//g) under the heating rate of 10.degree.C/min, pyrolysis temperature of 900.degree.C, the particle size of 12-16 mesh, the activation gases of CO/sub 2/, and the soaking time of 80 minutes. Therefore, it is feasible to manufacture the microporous activated carbons from corn cob agrowaste by using clean technology, namely, physical activation
