摘要

本研究以牛糞為材料，分別在不同炭化溫度（500、550、600°C）與活化溫度（750、800、850°C）之條件以水蒸氣活化法製備活性碳，探討其孔隙性質。結果顯示，牛糞活性碳之收率介於為4.45～24.46 %，其受炭化溫度與活化溫度所影響。而以炭化溫度500°C、活化溫度750°C者最高，達24.46 %；pH介於10.41～11.54之間；碘值為379.4～661.9mg/g，亞甲基藍吸附量為245.1～829.4mg/g；BET比表面積為349～587m^2/g，孔隙結構均以微孔為主。又知活性碳之pH、碘值、亞甲基藍吸附值、BET比表面積均隨活化溫度上升，而有提高之趨勢。

In this study, activated carbons were produced with steam activation from cattle manure at different levels of carbonization temperatures (500, 550 and 600°C) and activation temperatures (750, 800 and 850°C). The pore structure of the activated carbons was investigated. The results showed that the yields of cattle manure-made activated carbons were ranged from 4.45% to 24.46%. The activated carbon made at carbonization temperature of 500°C and activation temperature of 750°C had the highest yield (24.46%). The pH value of activated carbons varied in the range from 10.41 to 11.54; iodine value and methylene blue value were 379.4~661.9mg/g and 245.1~829.4mg/g, respectively; BET specific surface area were between 349~587m^2/g, and the pore structure were belonged to micropores. With the activation temperatures increasing, the pH, iodine value, methylene blue value and specific surface area of cattle manure-made activated carbon increased as well.
