FT-IR Investigation of the Structural Changes of Sulcis and South Africa Coals under Progressive Heating in Vacuum: Correlation with Volatile Matter
Figure 6
FT-IR spectra in the 2000–400 cm−1 region of gases obtained at different temperatures from Sulcis (—) and South Africa (- - -) coals sampled in the cooling trap (c). E = ethers, K = ketones, H = aliphatic hydrocarbons (saturated and unsaturated).
