 note = {Abstract Japanese cedar (Cryptomeriajaponica D, Don) bark was pyrolyzed in a stream of N, at
473-673 K for 3-12 h under atmospheric pressure. The resultant carbonaceous residues were
activated in a stream of CO2 at 1173 K for 1 h. Adsorption of N2 at 77 K was measured to
investigate the pore structure and the surface properties of the pyrolyzed and activated materials
from the cedar bark. Both specific surface areas and total pore volumes of the materials pyrolyzed
at temperatures below 573 K were small, indicating that pore structures were not developed under
mild conditions. However, those of the samples heated at 673 K increased with increasing time of
the treatment, during which micro porosity was mainly developed. Activation of the pyrolyzed
cedar bark led to drastic increase in specific surface area and pore volume. The increase was due to
the selective formation of the micro pores which distributed mainly less than 0.35 nm in radius.
Analytical results of adsorption data using t-plot and a ,-plot and IR spectra methods suggest
that the surface properties of both pyrolyzed and activated cedar bark are different from those of
typical carbon black. It is indicated that organic moiety and oxygenated functional groups
originated from cedar bark may affect the surface characteristics of pyrolyzed and activated cedar
bark.},
