Abstract

Coal pyrolysis

coke

Mössbauer

pyrite

sulfur

Well characterized, an Egyptian coal sample (EM-87) has been carbonized in an Argon atmosphere of pressure 10 5 Pa at different temperatures from 700-1000 K. The analysis of the Mössbauer spectra collected at room temperature for the produced semi-cokes, showed that pyrite FeS 2 was starting to be transformed to pyrrhotite Fe 1-x S at 700 K. This transformation was found to be increased when the pyrolysis temperature was increased.
