Read More1998-6-25 · Coal is an organic rock (as opposed to most other rocks in the earth's crust, such as clays and sandstone, which are inorganic); it contains mostly carbon (C), but it also has hydrogen (H), oxygen (O), sulfur (S) and nitrogen (N), as well as some inorganic constituents (minerals) and water (H2O).
Read MoreWhy is coal composition and quality important to gas analysis? To begin with, the chemical composition of coal is analyzed by proximate and ultimate analyses (ASTM, 1993).Proximate analysis determines by using set procedures regarding moisture, volatile matter, fixed carbon, and ash content (Figure 5.21).Proximate analysis is reported by percent on as-received, moisture-free, and moist- and ...
