FT-IR Investigation of the Structural Changes of Sulcis and South Africa Coals under Progressive Heating in Vacuum: Correlation with Volatile Matter
Figure 7
(a) Plots of the pressure values of noncondensable gases against temperatures for Sulcis and South Africa coals. (b) FT-IR spectra in 3500–400 cm−1 region of noncondensable gases obtained at various temperatures by Sulcis (—) and South Africa coals (- - -). A = acetylene.
