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:
---------------------------------------------------------------------
v/cm~(-1) group 10~2 k/s~(-1) E_a/kJ mol~(-1)
----------------------------
500 ℃ 550 ℃ 600 ℃
---------------------------------------------------------------------
3690 OH 2.92 9.05 9.26 68.1
2920 CH 5.16 9.47 12.8 53.5
1600 Aromatic 1.85 2.03 6.22 71.9
C=C
1035 Asymmetric 2.05 4.21 8.31 81.1
