摘要: Abstract Transformation of various sulphur forms, including inherent and added pyrite, sulphates (CaSO 4 FeSO ) organic sulphur, during pyrolysis an Australian lignite was studied using TGA, TGA-MS a fixed bed reactor, supplemented by form analysis. It shown that hydrogen sulphide (H 2 S) small quantity dioxide (SO were released the pyrite-lignite blend. However, only SO detected with high pyrite content. Inorganic matter found to help retaining some inorganic in char. Inherent decomposed at much lower temperatures than sulphates, releasing rather H S. The dominated iron which started decompose release around 500 K all sulphate had been 1073 K. retention higher its acid washed sample, due interaction between solid phase. gas produced lignite. A comprehensive mechanism transformation proposed.
