Abstract: Xinjiang Hutubi coal was selected to prepare activated carbon, in order to study the influence of activation process on
properties of activated carbon. The highly qualified char were prepared by carbonization process which was designed according to
the thermogravimetric analysis result of the coal, and activated carbon was prepared by activating the char in different activation
processes. The results indicated that activated carbons prepared from Hutubi coal showed good adsorption performance and pore
structure; by activating with H2O(g), activated carbon prepared at lower activation temperature had better adsorption performance,
pore volume and specific surface area, and activated carbon prepared at higher activation temperature had smaller size of
micropore; compared with activating with H2O(g), activated carbon prepared by activating with CO2 had better comprehensive
performance. The activation time of KNO₃ catalytic activation could be significantly reduced, but the activated carbon has poorer
pore structure and adsorption performance.

Key words: Hutubi coal; activated carbon; adsorption performance; pore structure
