摘要：

Four coals of different rank (one anthracite, one bituminous and two lignites) were flash-pyrolysed temperatures between 700 and 1200 degrees C in a heated wire mesh reactor at atmospheric pressure. The yields of Volatile sulfur-containing products (H2S, COS, CS2 and thiophenic compounds) were determined as a function of pyrolysis temperature by gas chromatography with flame photometric detection. A single reaction model was used to describe the sulfur release and pre-exponential factors and activation energies were determined for each coal. The results showed a relation between coal rank and the kinetic parameters. The activation energy varied between 20 and 100 kJ mol(-1), the lowest values corresponding to the lignites.
