90.各種石炭炭化物のガス化反応速度の評価

抄録

The CO_2 gasification reactivity of chars produced under a relatively mild condition was investigated after identifying the pore structures and surface oxygen-containing functional groups of the standard coal samples. The reactivity was evaluated by measuring the rate of thermogravimetric loss at the. Burn-off 10%. Attempts were made to predict the reactivity of chars produced under a condition of high temperature and pressure using the data. These data allowed estimation formula to be obtained by using ultimate analyses. It was expected that the reaction of coal chars in a severe condition could be predicted from the RP data.
