51.石炭チャーのCO_2ガス化反応性におけるチャーの活性点数の評価

抄録

At the most fundamental level gasification reactivity of carbon in char depends greatly on fraction of active sites in carbon. A CO_2 chemisorption's temperature-programmed desorption (TPD) method was used to estimate the number of active sites of the chars at several levels of carbon conversion. The experimental results gave the reasonable relationship between CO_2 gasification reactivity of the char and the number of active sites in char.
