摘要(Abstract)：

研究了以农业秸秆经压块成型后为原料,采用水蒸气活化法制备活性炭工艺。讨论了炭化温度、炭化时间、活化温度和活化时间对活性炭的得率和吸附性能的影响,得到了最佳工艺条件:炭化温度450℃、炭化时间6h、活化温度850℃、活化时间3h。经后处理去灰分后,制得的活性炭的亚甲基蓝吸附值达180 mg·g-1。基本能达到木质净水用活性炭标准要求,具有较大的推广应用前景。
In this paper,studies were made of the yield and adsorption properties of the actived carbon and the process of preparing activated carbon by using agricultural waste straw and the water vapor activation method. Discussion was made on according to the carbonization temperature,carbonization time,activation temperature and activation time,thus obtaining the optimum process conditions: carbonization temperature of 450℃,6 hours of carbonization time,850℃ of activation temperature,and 3 hours of activation time.The methylene blue adsorption value of activated carbon was 180 mg·g- 1after the ash content of postprocessing. The basic energy could reach the standard of activated carbon for water purification,and it had a great prospect of popularization and application.
