- Carbonization of ultra-fine woody powder using graphitization catalyst
抄録
This study aims to synthesize the bio-carbon with electro conductive properties by using graphitization catalyst synthesize from the woody carbon. In order to obtain the new functional bio-carbon, we prepared two initial powders. The two powdered samples (<Ⅰ>,<Ⅱ>) of cypress with different micro-structure were used for carbonization at 550~850°C and Fe-catalyzed carbonization at 850°C. The samples <Ⅰ> was prepared by pulverization of cypress chips with a wet cutter mill, which retained a micro-structure of coniferous wood . The sample <Ⅱ> was prepared by crushing the solid substance after drying the woody paste obtained by grinding the samples <Ⅰ> with a wet disk mill into ultra finely cellulose- fibrils. The carbon yield in carbonization and specific surface area were measured and XRD analysis was carried out for the carbonized products (chars) of both samples. The carbon yield for the sample <Ⅱ> was higher, and the specific surface area of the chars was considerably low compared with those for the samples <Ⅰ> and the chars. In Fe-catalyzed carbonization, it was confirmed that loaded Fe catalyst reacted with carbon atoms to form quantitatively Fe3C during carbonization and the crystallite size of char increased with increasing of amount of Fe loading up to 5 wt.%, but no definite difference in crystal structure between the chars of sample<Ⅰ> and <Ⅱ> was found. Fe3C contained in char could be easily removed by acid treatment. Specific surface area measured for the removed chars of sample <Ⅱ> was considerably high compared with that of carbonization without use of catalyst.
