This study aimed to clarify the behavior of closed pores in coal chars during pyrolysis and gasification process. Closed pore volume was calculated in terms of helium density and ash fraction. Closed pore surface area was calculated based on Small-Angle X-ray Scattering (SAXS). Closed pore volume of caking model sample chars was larger than that of non-caking model sample chars. The caking probably influences the generation of closed pores at pyrolysis as well as coal chars. Also, closed pore surface area, number of closed pores and closed pore volume are rapidly decreased at an initial stage of char gasification. They might be indicated that closed pore was opened at an initial reaction, and degree of contribution for gasification can be calculated.
