Abstract
|
|
|
|
This study is to investigate the relationship between pore structures of activated carbons and adsorption characteristics of toluene vapor using dynamic adsorption method. The surface areas of below in the pore diameter of activated carbons used in this experiment were in the range of 72 -93 % of total cumulative surface area and the toluene vapor equilibrium adsorption capacities were in the range of 350 - 390mg/g. Activated carbons having larger toluene adsorption capacity than the compared activated carbons had relatively pores in the pore diameter range of . Linear relationship between equilibrium adsorption capacity and cumulative sur- face area was in the diameter range of over . It was thought that toluene vapor was relatively well adsorbed on surfaces of pores of over .
