Activated carbon ceramics were prepared by using diatomite and three different types of activated carbon powder as main materials followed by shaping and calcining processes. The properties such as bulk density, compressive strength, porosity and iodine absorption were tested and thus the optimal technical conditions were determined. The inlfuences of sintering temperatures, activated ambient temperatures and adsorption time on benzene absorption capacity were characterized. The results show that the optimal ratio (by mass) for diatomite to coal activated carbon was 7:3, and the best sintering temperature was 800℃. Benzene absorption capacity of the materials made under the conditions was up 12.68% at 30℃for 24h. Activated carbon ceramics exhibit a maximum capacity at ambient temperatures at 30℃for72h.
