34.各種石炭のガス化進行に伴う反応性変化とチャーの基礎物性

抄録

Chars prepared from 35 raw coals and their demineralized coals were gasified under atmospheric pressure of CO_2 at 1173K. In order to clarify the reason of various gasified profiles with conversion, some physical and chemical properties of residual chars with diffrent conversions were measured. The results indicated that modification of some mineral matters in the chars and clystallinity of carbon would have close relation to the gasification rate.
