内容記述 |
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. |
