• INTERACTIONS OF CHLORINE AND SULPHUR COMPOUNDS IN .

    In the processes of coal carbonisation both chlorine and sulphur show high thermal mobility. During combustion of coal about 95% of sulphur contained in coal and about 90÷99% of chlorine are emitted to the atmosphere. Sulphur evolves mainly in form of sulphur dioxide (SO2) and chlorine as hydrogen chloride (HCl) (Osborn, 1992, Łucoś, 1995;). During coking process of .

  • Variable coalifiion; the processes involved in coal ...

    Materials contributing to coal differ in their response to diagenetic and metamorphic agencies and the three essential processes of coalifiion are called incorporation, vitrinization, and fusinization. The processes are defined on the basis of important petrographic characteristics. A diagram is given illustrating the extent of change in the plant material, in comparison with .
