摘要
Thermal analysis data on the oxidation reaction between air and active carbons obtained during activation by carbon dioxide are presented. The correlation between the modified DTA curves and the TG curves leads to the conclusion that the oxidation of active carbons in the temperature range from 20 to 1000° is a two-step process. It is pointed out that the oxidation reactions in the low-temperature region (450-550°) are governed by the oxygen content of the samples, whereas the reactions in the higher temperature region (550-850°) are controlled by the diffusion process. © 1979 Wiley Heyden Ltd., Chichester and Akadémiai Kiadó, Budapest.
