A set of seven bituminous coal chars has been characterised by IR spectroscopy (FTIR), thermogravimetry (TG) and elemental analysis. FTIR study provided suitable information to establish differences between coal samples according to their chemical compositions. The reactivity of these samples was also studied and correlated with the coal parameters of mean vitrinite reflectance, fuel ratio and H/C ratio. The data suggest that reactivity as determined can be correlated with the mean vitrinite reflectance, fuel ratio and H/C ratio (0.90). The order of reactivity of samples were; Amasra (S1) (R-m=0.65)>Azdavay (S4) (R-m=0.99)approximate toArmutcuk (S2) (R-m=0.81)approximate toAcenta (S3) (R-m=0.92)>Ac2l2k (S6) (R-m=1.11)Cay(S5)(R-m=1.03)>Sogutozu(S7)(R-m=2.14).
