| Abstract: | Japanese cedar CCryplomeriajaponica D. Don) bark was pyrolyzed in a stream of N2 at 573-1273
K for 3-12 h under atmospheric pressure. Fibers of the cedar bark that mainly comprise
cellulose, hemicellulose and lignin shrunk during heat treatment. However breaking down of the
fibers was not observed during the pyrolysis, leading to the formation of fibrous carbon materials
from cedar bark. The development of micro porosity was observed for the materials pyrolyzed at
temperatures above 773 K. The increase in specific surface area and total pore volume was due to
the selective formation of micro pores which were distributed sharply around 0.32 to 0.4 nm in
radius. Analysis of adsorption data by I-plot and a ,-plot methods suggest that the properties of
the surface of carbonaceous cedar bark pyrolyzed below 873 K are quite different from those of
typical carbon black, while those of cedar bark pyrolyzed at 1073-1273 K are similar to that of
carbon black. It is indicated that organic moiety and functional groups originated from cedar
bark may affect the surface characteristics of pyrolyzed cedar bark under relatively mild
conditions. |
