Abstract

In order to produce charcoal with a high specific surface area, the effects of temperature and carbon dioxide in carbonizing atmospheres on the specific surface areas of charcoal carbonized from waste wood were examined. The results were as follows :<br>(1) The specific surface area of charcoal carbonized at 1173 K in N₂+CO₂ atmosphere from waste wood is 1124 m²/g, which is comparable to that of activated carbon.<br>(2) The specific surface areas of charcoal carbonized at temperatures of 1073 and 1173 K in N₂+CO₂ atmospheres increase as the yields of the charcoals decrease.<br>(3) The experimental results revealed that the reaction of C+CO₂ = 2CO promotes and enlarges the specific surface area of the charcoal. Carbon dioxide in carbonizing atmospheres is effective in enlarging the specific surface area of charcoal made from waste wood.
