An activated carbon with high micro and mesoporosity, as well as a high bulk density, was fabricated by activating the extrusion-molded precursor made from carbonized rice husk (RH) and beet sugar (BS) at 850℃ in CO_2. The pore structure of this RH-based activated carbon (RHAC) was analyzed in relation to the bulk density. The extrusion molding and the use of BS syrup were useful to attain those superior properties. RHAC which was first activated for 1 h was immersed again in the BS syrup and then activated in CO_2 for 2 h. This two-step activation process provided both a high bulk density (0.93 g/cm^3) and a highly textured structure (micropore volume: 0.29 cm^3/g, mesopore volume:0.19 cm^3/g, BET specific surface area: 844 m^2/g).
