Dry gas cleaning was performed using four different commercial activated carbons at 150℃. Phenol and naphthalene were employed as a model compound of light tar produced from biomass gasification. The effect of physical characteristics of activated carbons was investigated on the adsorption behavior such as breakthrough curve and adsorption capacity using a fixed bed reactor. The breakthrough curve and adsorption capacity were largely dependent on the type of activated carbons. The adsorption capacities for phenol and naphthalene were 6.7-11.9 g/100g-AC, 19.9-23.7 g/100g-AC, respectively. For highly adsorption capacity, larger specific surface area was needed and appropriate ratio of average pore diameter to tar molecular diameter would exist while the particle size hardly affected adsorption capacity.
