Columnar activated carbons (ACs) were prepared from the bituminous coal/poplar blends using KOH as an activation agent by varying the mass ratio (bituminous coal/poplar and KOH/carbon materials). The specific 2D-NLDFT surface area and total pore volume of the prepared ACs are in the range of 436–825 m2/g and of 0.193–0.360 cm3/g, respectively. The pore size distribution of ACs show that most of the pores are in the range from large micropores to small mesopore and their distribution can be controlled by the both mass ratio. And the obvious differences in surface morphology between wood and coal phase, as expected from the intrinsic property of the two materials, were observed from SEM images, the former was irregular, heterogeneous, and highly porous, while the latter shown a smooth, regular surface.
