摘要: Abstract The Mossbauer effect is used to study in-situ transformations of pyrite under conditions coal liquefaction based on Illinois No. 6 from St. Clair County. A marked reduction observed at high temperatures in the isomer shift iron sulphides during liquefactions. By contrast pure do not show such a strong presence solvent and hydrogen. This may result covalent bonding between pyrrhotite surfaces coalderived liquid gases. Marked broadening linewidth Fe 1 − x S occurs above 300 °C stoichiometries pyrrhotites formed different runs were determined correlation was total amount sulphur deficiency . Coal-derived liquids are more active enhancing decomposition than tetralin. Both H 2 seem be actively involved process.
