초록

DTA에 衣한 國産無煙炭의 燃燒反應過程을 速度論的으로 解析할 수 있는 아래의 關係式을 導出하였다. $K=\frac{C_3{\cdot}W_0}{{\Delta}H{\cdot}{\Delta}C{\cdot}M{\cdot}S_A}(\frac{dy}{dt}+A(y-y_3))$ 이 式을 利用하여 各炭種에 對한 活性化 energy값을 求한 結果 非黑鉛性炭種은 40Kcal/mole, 黑鉛性炭種은 45Kcal/mole로서 炭化度가 增加되면 活性化 energy값이 增加된다는 것을 알았다. 無煙炭을 空氣中에서 燃燒시킬때 溫度에 衣하여 d_{(002)}$ X-線回折强度가 점차적으로 커지는 現象으로부터 無煙産中의 一部가 層構造(黑鉛化)로 變化됨을 알았으며 이 變化된 層構造에 生成된 $CO_2$의 一部가 接觸分解되어 다시 CO로 환원됨을 알았다. 그리고 無煙炭의 反應性을 左右하는 活性基의 種類는 -OH, -SH, -NH, -$CH_2-CH_3,$ 및 -CO, -COC-, -COOH가 存在하며 IR 로서 炭化度를 測定할 수 있었다

The rate Constants and energies of activation for the Combustion reaction of Korean anthracites have obtained by DTA method using the following rate equation derived by authors. $K=\frac{C_3{\cdot}W_0}{{\Delta}H{\cdot}{\Delta}C{\cdot}M{\cdot}S_A}(\frac{dy}{dt}+A(y-y_3))$ The anthracites of various ranks were treated at the different temperatures in the furnace. The probable combustion reaction mechanisms have discussed with the results obtained by the X-ray diffraction method, IR spectroscophic analysis, and gas chromatography. By the intensity of d(002) Values, it was confirmed that a parts of the amorphous carbon was converted to graphite form by heat treatment. The appreciable amounts of CO gas were expelled in the combustion process and it appeared that a little amount of the gas came from the catalytic decomposition of anthracites, The functional groups such as -OH, -SH, -NH, $-CH_2-CH_3,$ -CO, -COC-. and polycondensed aromatic rings in anthracites have observed by IR spectrophotometric analysis.
