Black coal equivalent (BCE) is an export coal product derived from the
Overview
Densified coal as a black coal equivalent product derived from brown coal was first discovered by R. B. Johns and colleagues at the Organic Chemistry laboratory at Melbourne University following observations made at the
Characteristics
The performance characteristics of black coal equivalent densified coal derived from brown coal is benchmarked[2] 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 black coal.
