66 ハイパーコール配合炭のコークス化機構(コークス品質,抽出物添加)

抄録

Thermal extraction using industrial solvents has been applied to produce ash-free coal called HyperCoal. HPCs have wide thermoplastic temperature ranges, in addition to the high thermoplasticity itself. Thus, HPC was tried as a thermoplasticity accelerator for cokemaking. When the HPC was mixed instead of a caking coal in coal blends, a significant improvement in the thermoplasticity of coal blends was observed. In the present work, HPCs produced from various coals of ranks were blended with standard coal blends, and the effect of HPC adding on the caking and coking properties of the coal blends was investigated.
