Hyper-coal (HPC) is produced by coal extracted and separating insoluble component (residue-Coal; RC) from soluble component. HPC has an excellent thermoplastic property and a large potential for coke additive to make a strong coke. The thermoplasticity of Hyper-coal depends on the separation efficiency in the solid-liquid separation processes. The process adapts the gravity settling velocity to separate RC from liquid. Therefore the settling velocity of RC is the most important factor to design the separation process for the plant. On the other hand, the actual settling velocity is not cleared in the high temperature and high pressure conditions. In this research, we measured the actual RC settling velocity in the high temperature and high pressure conditions on batch settling tank. That enables to design the separation process as designing thickener.
