マイクロ波プラズマを利用した超高速賦活法で作製した活性炭の構造に関する研究

摘要

Activated carbon(AC)is a common adsorbent that has hierarchical porous structures including micropores(pore diameter<2 nm)and mesopore(2ore diameter<50 nm)with high surface area.AC has been widely used in water purification,gas filter,and catalyst support.Conventional production processes of AC are always operated in batch system due to long activation time(6 to 12 h).In authors'previous work1),AC with high surface area of 2,084 m~2 g-1 can be produced by microwave-activation time of 330 s,which is remarkably fast compared to the conventional methods.The objective of the present work is to investigate the influence of microwave-retention time on pore formation at AC prepared by the activation using microwave-induced plasma with KOH,called MiWP-KOH activation.
