Black coal equivalent to around 5800 kcal/kg; and creating a ‘densified coal’ product that is hydrophobic, no longer prone to spontaneous combustion, and readily transportable. The performance characteristics of black coal equivalent densified coal derived from brown coal is benchmarked against the comparative burning properties of black coal mined and exported from mining regions in Tarong, Queensland and Newcastle, New South Wales, Australia. Black coal sourced from Tarong and Newcastle constitute the bulk of black coal currently exported by Australia. Black coal equivalent has become an attractive option to coal importers from countries with no or few reserves of domestic of black coal.
Cannel coal the Drake Oil Well in 1859, made petroleum a cheaper raw material for making kerosene and drove the American oil shale industry out of business. Cannel coal is brown to black oil shale. It comes from resins, spores, waxes, and cutinaceous and corky materials of terrestrial vascular plants, in part from Lycopsid (scale tree). Cannel coal was accumulated in ponds and shallow lakes in peat-forming swamps and bogs of the Carboniferous age under oxygen-deficient conditions. Thus cannel coal seams are shallow and often found above other deposits, while the coal itself, being rich in oils, burns long, with a bright
