Reaction of CO2 with Korean Anthracites at Temperature of 850℃ to 1100℃

무연탄의 반응성 (제2보) 국산무연탄의 반응성과 온도
Tae Hee Hahn

The rates of reaction of various Korean anthracites with carbon dioxide were measured at temperatures ranging from 850℃ to 1100℃ with coal -6, +8 sieve size and the residence time of reactant gas in the fixed coal bed 14.0 to 15.0 seconds. The primary variables studied were the coal sources and temperature. The reactivity was considerably varies with the coal sources and the general trends show that the reactivity sharply increases with increasing reaction temperature except the Yongwoll coal where the increase is not so sharp, which is considered to be due to high reactivity and high-pore structure of the coal. It was also found that a straight line was produced when a logarithm of the rate constant is plotted against the reciprocal of the absolute temperature up to 1000℃, but above that temperature it deviates from linearity. The information obtained will be of value in the design of the coal gasifier using Korean anthracites.
