    In general, a high level of fixed carbon in the coal is always preferable and desirable. it should be noted that fixed carbon and total carbon are usually not the same. total carbon represents the carbon present in the coal under normal conditions. fixed carbon is determined by heating the coal to 900c in the absence of air, thus burning away all volatiles including carbon in hydrocarbons. the carbon remaining after this treatment is called fixed carbon. when it comes to using coal as a solid reductant, fixed carbon is more important than total carbon.

  • A look at the process of pelletizing iron ore for steel

    Volatiles are basically the material present in coal that is burnt away when coal is heated to 900c without air being present. coal with low volatile matter is preferred since any chemical or calorific value in the volatiles is typically wasted, though it is sometimes possible to capture some of that value. rk-based processes can handle coal with higher volatile matter ranging from 6 to 40 as volatiles are already burnt away before they enter the kiln. rhf-based processes prefer coal with less than 25 volatiles 38,39.

    Free swelling index is a measurement of increase in volume when coal is heated under specified conditions. a standard method astm d720-91 2010 can be used to measure this characteristic. although it is still not completely clear what affects the free swelling index of coal, it is believed to relate to the coals plastic properties. the free swelling index tends to be higher if coal exhibits plastic properties and contains high volatiles. anthracite coal typically has a low free swelling index, which makes it preferable in most instances over typical bituminous coal 42.
