摘要: Abstract Transformation of pyrite in an Australian lignite during pyrolysis was studied using a thermogravimetric analyser (TGA) and fixed-bed reactor. Samples with high content, pyrite-free lignite, acid-washed mineral, blended various amounts the minerals were employed experimentation. It shown that nitrogen mineral (S/Fe = 2) decomposes to troilite (S/Fe = 1) at ca. 1200 K above this temperature, some further form elemental iron (S/Fe
