Thermal Decomposition of Coal - EOLSS

2017-1-16  The thermal decomposition of coal by slow heating rate is generally used to investigate carbonization of bituminous coal for coke making. It means that the thermal decomposition of coal under non-oxidizing conditions produces a residue (coke), which consists of carbon and mineral matter. During this process the coal passes through several stages.
