Micro and mesoporous carbon/silica composite (CSC) materials were fabricated from rice husk and beet sugar. The pore structure of CSC activated at 875℃ in CO_2 for 0.5-2.5 h was analyzed in relation to bulk density. The activation time of 2.0 h provided the largest total pore volume and BET specific surface area (0.68 cm^3/g and 1027 m^3/g), but low bulk density (0.54 g/cm^3). CSC of which activation time was 1 h was once again immersed in the beet sugar syrup and then activated in CO_2 for 1 h. This two-steps activation provided high bulk density (0.69 g/cm^3) and high micro and mesoporous structure (BET specific surface area: 943 m^2/g, total pore volume: 0.56 cm^3/g, micropore volume: 0.32 cm^3/g, mesopore volume: 0.19 cm^3/g).
