WebWhy 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 ). WebThe fixed carbon content of the coal is the carbon found in the material which is left after volatile materials are driven off. This differs from the ultimate carbon content of the coal because some carbon is lost in hydrocarbons with the volatiles.
