"HyperCoal" (ash-free coal) is produced by thermal extraction using cost-effective industrial solvents below 400℃ in an inert atmosphere. It has originally a wide thermoplastic temperature range, in addition to a high thermoplasticity itself. HyperCoal was used as a thermoplasticity accelerator for coal blends containing a significant amount of slightly-caking coals. When HyperCoal was mixed in coal blends instead of a caking coal, a significant improvement in the thermoplasticity of the coal blends was observed. In the semicoke strength test, the addition of HyperCoals produced from a low-rank Pasir coal gave higher strengths than the standard blend; the same occurred with the HyperCoal from a caking coal. Furthermore, on adding the same amount of HyperCoal, a smaller weight loss occurred during carbonization, and higher tensile strength was achieved.
