摘要: 本文用红外光谱检出了我国河北峰峰煤矿黄沙肥煤中的主要官能团, 定量地研究了该煤在裂解过程中主要官能团, OH、CH_2、C—O—C、芳香族稠环等的反应动力学。求出各种官的团在不同裂解温度下的反应速率常数、反应级数及表观活化能。

Abstract: The groups, OH, CH_2, CH_3, C—O—C etc. in fat coal from Feng-Feng in He-Bei province has been examined. The disappearance kinetics of these groups were also determined by IR method. The results showed that the disappearance reactions for these groups followed first-order reaction.The rate constants and corresponding activation energies to each reaction are:
