The objectives of this study are to evaluate char component from pyrolysis of MSW as an applicable solid fuel and to research the mechanism of dechlorination during the pyrolysis not only by establishing the material balance but also by understanding the Cl behavior into pyrolysis products.<BR>The pyrolysis experiments have been performed with a RDF (Refuse Derived Fuel) obtained from actual MSW as a model sample. The RDF is pyrolyzed by an externally indirect heat source for an hour under nitrogen gas stream (7×10<SUP>-2</SUP>cm/s) at 250-800°C.<BR>The results show that; (1) The pyrolysis temperature of 500-600°C may be optimal to pyrolyze the RDF.(2) The char obtained by the pyrolysis can be used as a substitute for bituminous-class coals, meeting the following process targets: (1) Calorific value (d.a.f.), 32000-34000kJ/kg; Fuel ratio (ratio of fixed carbon to volatile matter), about 2 (-); (3) Degree of carbonization (H/C atomic ratio), 0.5 (-).(3) Provided the char formed by the pyrolysis below 600°C is subjected to be washed with water, the chlorine content in it could be reduced to the target (0.3-0.5wt%).
