抄録

The development of pore structure of char during gasification was evaluated using TG gasification profiles and Raman spectroscopy of KZ char. The pore structure of char during CO₂ gasification reflected the initial one because CO₂ gasification proceeds on the pore surface. In contrast, the pore structure during steam gasification was developed probably owning to the growth of aromatic structures by H radicals and selective small aromatic consumption. These different mechanisms of pore structure development imply the difference of gasification reaction mechanisms.
