OSTI ID:504591
It has been shown that the mineral matter contained in Victorian brown coal is released to some extent during rapid pyrolysis. The fate of four inorganic species: sodium, calcium, magnesium, and iron, has been investigated. As expected, sodium is released from the coal during heating. However, the divalent species calcium, magnesium and iron, are all released during pyrolysis, with losses of between 35 and 40% where the total mass loss from the coal reaches at least 70%. A mechanism has been postulated for the loss: these elements are believed to be retained within the large molecular weight tar fraction which makes up between 30 and 40% of the mass loss from the coal during rapid pyrolysis.
